Purpose and audience

Year 9
Identify the purpose and audience of a non-fiction source, and how the form shapes them (KS3 reading, R1)
Video lesson: Purpose and audienceComing soon
Context. Four sources discuss one question: should secondary school start later in the day? Each is written for a different reader and with a different purpose. Before you judge any source, ask who it is for, and what it wants the reader to do.

Source A: a newspaper comment column (original, fictional paper)

1Every parent knows what happens when the alarm goes off at eight. The children are still in bed, and the school gates are full of yawns.

2Our pupils deserve a proper day, and the answer is simple: start earlier and finish earlier, as we always did.

3The Eastfield survey proves it. Ninety per cent of pupils said they would rather finish by three.

4Teachers already know the truth. A later start is a fashion, and fashions do not teach maths.

Source B: a leaflet from a sleep charity (original, fictional charity)

1Teenagers need around eight to ten hours of sleep each night.

2Their body clocks shift later during adolescence, so many are alert late at night and tired early in the morning.

3A later start can help. In one trial at a school in another county, attendance rose by four per cent after the start moved from 8.30 to 9.15 a.m.

4That trial had 180 pupils and ran for one term, so the results may differ elsewhere.

Source C: a letter to the editor (original, fictional writer)

1Dear Editor,

2My son's school has moved to a later start, and I now see him leave the house at a quarter past eight with his breakfast in his hand.

3I am sure it is good for him, but I worry about the traffic outside the gates and how he will get home in the dark in winter.

4Perhaps the answer is a trial, with parents asked first. Anita Shah, Northmoor.

Source D: a summary of a school trial (original, fictional school)

1Summary of the trial at Brackenfield School.

2From September, the start for Years 7 to 9 moved from 8.30 a.m. to 9.15 a.m. for one term.

3Attendance for these years rose from 92.1 per cent to 93.0 per cent, and lateness fell by 14 per cent.

4Staff reported no change in exam marks over the term. The governing body will review the trial in July.

Key ideas

  • Purpose is what the writer wants to achieve: to persuade, inform, report, or express a view.
  • Audience is who the writer expects to read the text, and how that shapes the language.
  • Form (comment, leaflet, letter, report) gives clues about purpose and audience.
Worked example 5.1.1
What is the main purpose of Source A?

Method. Look at the verbs and claims, then say what the writer wants the reader to do.

  1. Read the claims. It says the answer is to start earlier and finish earlier.
    start earlier and finish earlier
  2. Look at the tone. It uses a confident, firm tone, with a clear call to action.
    firm
  3. Name the purpose. The writer wants readers to agree that the start should be earlier.
    to persuade readers that schools should start earlier
  4. Write the answer.
    to persuade readers that schools should start earlier

Check. The purpose is supported by the claim and tone. ✓

Worked example 5.1.2
Who is the audience of Source B? Choose one: parents and young people, to inform them about sleep, teachers only or government ministers only.

Method. Test each choice against the sentence or the text.

  1. Read what the question asks for. Decide what the sentence or the text needs.
  2. Test the choice. A leaflet from a sleep charity is written for families, to explain sleep and what a trial found.
    parents and young people, to inform them about sleep fits
  3. Reject the other choices. The leaflet does not address teachers only or ministers only.
    teachers only and government ministers only do not fit
  4. Write the answer.
    parents and young people, to inform them about sleep

Check. The choice fits the sentence or the text. ✓

Worked example 5.1.3
Which source is most like a formal report?

Method. Compare the form and the language of each source.

  1. Look at the title. Source D is titled as a summary of a trial.
    Summary of the trial
  2. Look at the language. It gives dates, numbers and staff reports, without a call to action.
    staff reported
  3. Decide. Source D is the most like a formal report.
    Source D
  4. Write the answer.
    Source D

Check. The form and the language match a report. ✓

Watch out

Watch out: purpose and audience are not the same. A text can inform one audience and persuade another.

Exam tip

Exam tip. Name the purpose, the audience, and one piece of form or language that shows it.

Exercise 5A  Practice: purpose and audience

1
FCopy the words that describe the school gates in Source A.
2
FIn which paragraph does Source A make its call to start earlier? Write the number.
3

4
FWhich word in Source D shows the writer is reporting facts? Choose one: rose, proves or fashion.
5
FWho is the audience of Source C?
6
FWhat does lateness mean in the phrase "lateness fell by 14 per cent"? Write the meaning in your own words.

8
FIn which paragraph of Source B is the trial first mentioned? Write the number.
9
FName the form of Source A, and say how the form suits its purpose.
10
FCopy the phrase in Source C that says the writer is worried.
11
RExplain how the tone of Source A differs from the tone of Source D.
12
RWhy might the same question produce such different sources?
5.2

Rhetoric: ethos, pathos and logos

Year 9
Identify and evaluate ethos, pathos and logos, and rhetorical language, in several sources (KS3 reading, R4)
Video lesson: Rhetoric: ethos, pathos and logosComing soon
Context. Writers persuade with three main appeals. Ethos is trust in the writer: their credibility. Pathos is emotion: fear, pity or hope. Logos is logic and evidence: facts, numbers and reasons. Good writers mix them, and the reader must judge which appeal works best.

Source A: a newspaper comment column (original, fictional paper)

1Every parent knows what happens when the alarm goes off at eight. The children are still in bed, and the school gates are full of yawns.

2Our pupils deserve a proper day, and the answer is simple: start earlier and finish earlier, as we always did.

3The Eastfield survey proves it. Ninety per cent of pupils said they would rather finish by three.

4Teachers already know the truth. A later start is a fashion, and fashions do not teach maths.

Source B: a leaflet from a sleep charity (original, fictional charity)

1Teenagers need around eight to ten hours of sleep each night.

2Their body clocks shift later during adolescence, so many are alert late at night and tired early in the morning.

3A later start can help. In one trial at a school in another county, attendance rose by four per cent after the start moved from 8.30 to 9.15 a.m.

4That trial had 180 pupils and ran for one term, so the results may differ elsewhere.

Key ideas

  • Ethos: the writer's credibility or authority, such as a charity's expertise or a teacher's experience.
  • Pathos: appeals to emotion, such as "the school gates are full of yawns".
  • Logos: appeals to logic and evidence, such as numbers, facts and reasons.
Worked example 5.2.1
Identify one example of pathos in Source A. Quote it.

Method. Find the emotional or vivid detail, then name the appeal.

  1. Look for an image. The gates are described as full of yawns.
    full of yawns
  2. Name the appeal. The image appeals to the reader's sense of tiredness and sympathy.
    tiredness and sympathy
  3. Quote it. The exact quotation is the school gates are full of yawns.
    the school gates are full of yawns
  4. Write the answer.
    the school gates are full of yawns

Check. The appeal is named with a quotation. ✓

Worked example 5.2.2
Which appeal does "Teenagers need around eight to ten hours of sleep each night" mainly use? Choose one: logos (facts), pathos (emotion) or ethos (trust in the speaker).

Method. Test each choice against the sentence or the text.

  1. Read what the question asks for. Decide what the sentence or the text needs.
  2. Test the choice. A specific range of hours is a factual claim, which appeals to logic.
    logos (facts) fits
  3. Reject the other choices. It does not describe feelings, and it does not say who the writer is.
    pathos (emotion) and ethos (trust in the speaker) do not fit
  4. Write the answer.
    logos (facts)

Check. The choice fits the sentence or the text. ✓

Worked example 5.2.3
What is the ethos of Source B?

Method. Think about who the writer is and why the reader might trust them.

  1. Find the author. The leaflet comes from a sleep charity.
    a sleep charity
  2. Judge the trust. A charity with a focus on sleep appears expert.
    appears expert
  3. Explain the effect. So the reader is likely to trust its advice.
    the reader is likely to trust its advice
  4. Write the answer.
    a charity with expertise, which makes the reader trust its advice

Check. The ethos is supported by the authorship. ✓

Watch out

Watch out: do not call an appeal "logos" just because it has a number. A number needs a clear source and a reason to be relevant.

Exam tip

Exam tip. Name the appeal (ethos, pathos or logos), quote the words, and say how far the appeal works on this reader.

Exercise 5B  Practice: ethos, pathos and logos

1
FWhich appeal does "Every parent knows what happens when the alarm goes off at eight" mainly use? Choose one: pathos, logos or ethos.
2
FWhich appeal does "Ninety per cent of pupils said they would rather finish by three" mainly use? Choose one: logos, pathos or ethos.
3
FWhich phrase in Source A most clearly uses ethos? Choose one: Teachers already know the truth, the school gates are full of yawns or A later start is a fashion.
4
FCopy the phrase in Source A that dismisses the later start as a passing trend.
5
FWhat does fashion mean in the phrase "A later start is a fashion"? Write the meaning in your own words.
6
FIdentify one example of logos in Source B, and quote it exactly.
7
FIdentify one example of pathos in Source C, and explain its effect.
8
FWhich is the most persuasive appeal in Source B? Choose one: logos, because the leaflet uses facts about sleep, pathos, because the leaflet is sad or ethos, because the leaflet is funny.
9
RJudge how far the ethos of Source A works. Give one reason.
10
RCompare the appeals of Source A and Source B. Which is more likely to convince a sceptical reader? Give one reason.
11
RExplain why Source B mentions the trial "in another county".
5.3

Reliability: evidence, sample and selection

Year 9
Evaluate the reliability of evidence, including sample size and selective use of data (KS3 reading, R4 and R7)
Video lesson: Reliability: evidence, sample and selectionComing soon
Context. A source can use evidence well, or badly. Ask what the evidence measured, how many people or events it covers, and whether the writer has selected only the results that support the argument.

Source A: a newspaper comment column (original, fictional paper)

1Every parent knows what happens when the alarm goes off at eight. The children are still in bed, and the school gates are full of yawns.

2Our pupils deserve a proper day, and the answer is simple: start earlier and finish earlier, as we always did.

3The Eastfield survey proves it. Ninety per cent of pupils said they would rather finish by three.

4Teachers already know the truth. A later start is a fashion, and fashions do not teach maths.

Source B: a leaflet from a sleep charity (original, fictional charity)

1Teenagers need around eight to ten hours of sleep each night.

2Their body clocks shift later during adolescence, so many are alert late at night and tired early in the morning.

3A later start can help. In one trial at a school in another county, attendance rose by four per cent after the start moved from 8.30 to 9.15 a.m.

4That trial had 180 pupils and ran for one term, so the results may differ elsewhere.

Source D: a summary of a school trial (original, fictional school)

1Summary of the trial at Brackenfield School.

2From September, the start for Years 7 to 9 moved from 8.30 a.m. to 9.15 a.m. for one term.

3Attendance for these years rose from 92.1 per cent to 93.0 per cent, and lateness fell by 14 per cent.

4Staff reported no change in exam marks over the term. The governing body will review the trial in July.

Key ideas

  • Sample size: a small sample, such as 180 pupils for one term, is less reliable than a large, long study.
  • Selection: a writer may quote a finding that supports the case and leave out the rest.
  • Relevance: check that the evidence measures the thing the writer claims it measures.
Worked example 5.3.1
Why is "The Eastfield survey" in Source A not good evidence that schools should start earlier?

Method. Read what the survey measured, then compare it with the claim.

  1. Read the survey finding. Ninety per cent said they would rather finish by three.
    Ninety per cent of pupils said they would rather finish by three
  2. Read the claim. The writer says the answer is to start earlier.
    start earlier and finish earlier
  3. Compare. The survey does not measure start time, so it does not prove the claim.
    the survey asked about finishing time, not start time
  4. Write the answer.
    the survey asked about finishing time, not start time

Check. The evidence and the claim are compared. ✓

Worked example 5.3.2
Which factor most limits the reliability of the trial in Source B? Choose one: it included only 180 pupils for one term, it used a famous author or it had a large budget.

Method. Test each choice against the sentence or the text.

  1. Read what the question asks for. Decide what the sentence or the text needs.
  2. Test the choice. A small sample over a short time may not apply to other schools.
    it included only 180 pupils for one term fits
  3. Reject the other choices. The author and the budget do not affect the sample size, and they are not in the trial description.
    it used a famous author and it had a large budget do not fit
  4. Write the answer.
    it included only 180 pupils for one term

Check. The choice fits the sentence or the text. ✓

Worked example 5.3.3
Which source is most likely to be biased toward one answer?

Method. Look for one-sided claims and selective evidence.

  1. Check the argument. Source A argues only for an earlier start.
    start earlier and finish earlier
  2. Check the evidence. It uses a survey about finishing time, which it presents as proof.
    The Eastfield survey proves it
  3. Decide. Source A is the most biased, because its evidence is selective.
    Source A is the most biased
  4. Write the answer.
    Source A, because it argues one view and uses a selective survey

Check. The bias is supported by two details. ✓

Watch out

Watch out: a large sample is not always reliable if it measures the wrong thing. Ask both how many and what.

Exam tip

Exam tip. Say what the evidence measures, how big it is, and whether it supports the exact claim.

Exercise 5C  Practice: reliability and selective evidence

1
FHow many pupils were in the trial in Source B? Write the number.
2
FHow many terms did the trial in Source B last? Write the number.
3
FWhat does the Eastfield survey in Source A measure? Choose one: the time pupils would like to finish, the time pupils would like to start or the exam results.
4
RGive one reason the trial in Source B may not apply to a school in your area.
5
FCopy the figure for attendance before the trial in Source D, with its unit.
6
FCopy the figure for attendance after the trial in Source D, with its unit.
7
FBy how many percentage points did attendance rise in Source D? Write the number.
8
PSCompare the size of the rise in attendance in Source B with the rise in Source D.
9
FWhich statement is best supported by Source D? Choose one: attendance rose a little, attendance rose by four per cent or exam marks rose.
10
RExplain why Source D is a more cautious source than Source A.
11
RJudge whether the claim "Teachers already know the truth" is supported by any evidence in the sources. Give one reason.
12
RExplain why a writer might leave out the rest of a survey, as Source A does.

Provenance: who wrote it, when, and why

Year 9
Consider the origin, date and purpose of a source when judging how far to trust it (KS3 reading, R4)
Video lesson: Provenance: who wrote it, when, and whyComing soon
Context. Provenance means the origin of a source: who made it, when, for whom, and why. A source written by a person with a stake in the result may be biased. A source that reports a measured result, written by someone who did the trial, may be more reliable.

Source C: a letter to the editor (original, fictional writer)

1Dear Editor,

2My son's school has moved to a later start, and I now see him leave the house at a quarter past eight with his breakfast in his hand.

3I am sure it is good for him, but I worry about the traffic outside the gates and how he will get home in the dark in winter.

4Perhaps the answer is a trial, with parents asked first. Anita Shah, Northmoor.

Source D: a summary of a school trial (original, fictional school)

1Summary of the trial at Brackenfield School.

2From September, the start for Years 7 to 9 moved from 8.30 a.m. to 9.15 a.m. for one term.

3Attendance for these years rose from 92.1 per cent to 93.0 per cent, and lateness fell by 14 per cent.

4Staff reported no change in exam marks over the term. The governing body will review the trial in July.

Key ideas

  • Provenance asks who wrote the source, when, and why, and whether they gain from the result.
  • A letter is one person's experience and is not a survey of many people.
  • A report of a trial is more reliable for what it measured, but limited to its own school and term.
Worked example 5.4.1
What is the provenance of Source C, and what does it tell the reader?

Method. Find who wrote it, then say what kind of evidence it is.

  1. Find the writer. The letter is signed by Anita Shah.
    Anita Shah
  2. Name the kind of evidence. It is one parent's experience, not a survey.
    one parent's experience
  3. Explain the limit. So it cannot show what most parents think.
    cannot show what most parents think
  4. Write the answer.
    a parent's personal letter, so it reports one family's experience

Check. The provenance and its limit are explained. ✓

Worked example 5.4.2
Which is the most reliable kind of evidence for the effect of a later start? Choose one: a measured trial with attendance figures, a single letter from one parent or a newspaper comment with no figures.

Method. Test each choice against the sentence or the text.

  1. Read what the question asks for. Decide what the sentence or the text needs.
  2. Test the choice. A measured trial gives figures from the school, which can be checked.
    a measured trial with attendance figures fits
  3. Reject the other choices. A single letter and a comment with no figures give only one view.
    a single letter from one parent and a newspaper comment with no figures do not fit
  4. Write the answer.
    a measured trial with attendance figures

Check. The choice fits the sentence or the text. ✓

Worked example 5.4.3
Why might the writer of Source D be more reliable than the writer of Source A?

Method. Compare the purpose and the evidence of each writer.

  1. Check the purpose of D. Source D summarises a trial for the governors.
    summarises a trial
  2. Check the purpose of A. Source A wants to persuade readers.
    to persuade readers
  3. Judge. A summary of measured results is less biased than a persuasive comment.
    Source D reports measured results and staff views, without a call to action
  4. Write the answer.
    Source D reports measured results and staff views, without a call to action

Check. The judgement compares purpose and evidence. ✓

Watch out

Watch out: a source is not false just because it has a purpose. Ask whether the purpose has shaped the evidence.

Exam tip

Exam tip. Name who wrote the source and why, then say what that means for the evidence.

Exercise 5D  Practice: provenance

1
FCopy the name of the writer of Source C.
2
FIn which paragraph of Source C does the writer suggest a trial? Write the number.
3
FWhat kind of text is Source D? Choose one: a summary of a school trial, a newspaper comment or a letter to the editor.
4
FCopy the phrase in Source D that says when the governors will review the trial.
5
FExplain how the provenance of Source C limits its reliability.
6
RInfer the writer's attitude to a trial in Source C. Quote one phrase.
7
FWhat does traffic mean in the phrase "the traffic outside the gates"? Write the meaning in your own words.
8
FWhich concern does Source C raise that Source B does not? Choose one: traffic and getting home in the dark, sleep hours or attendance rates.
9
RExplain why the writer of Source D might be more careful about the results than the writer of Source A.
10
FSummarise Source C in one sentence.
11
RWhy does the provenance of a source matter when you judge its evidence?
12
FWhich is the best reason to trust the figures in Source D more than the claim in Source A? Choose one: Source D reports measured results with dates and numbers, Source D is longer or Source D uses more emotive words.
5.5

Summarising one source

Year 9
Summarise the main points of one source in your own words, keeping the main point and dropping detail (KS3 reading, R6)
Video lesson: Summarising one sourceComing soon
Context. A summary of one source keeps its main point, its key evidence, and its purpose. It leaves out the small details and does not copy whole sentences. It is written in your own words.

Source B: a leaflet from a sleep charity (original, fictional charity)

1Teenagers need around eight to ten hours of sleep each night.

2Their body clocks shift later during adolescence, so many are alert late at night and tired early in the morning.

3A later start can help. In one trial at a school in another county, attendance rose by four per cent after the start moved from 8.30 to 9.15 a.m.

4That trial had 180 pupils and ran for one term, so the results may differ elsewhere.

Key ideas

  • A summary keeps the main claim and the main evidence, and drops minor detail.
  • Use your own words. Do not copy whole sentences.
  • A good summary is shorter than the source and accurate.
Worked example 5.5.1
Summarise Source B in one sentence.

Method. Find the main claim and the main evidence, then write one sentence.

  1. Find the main claim. A later start can help teenagers.
    A later start can help
  2. Find the main evidence. A trial showed attendance rose by four per cent.
    attendance rose by four per cent
  3. Write one sentence. Combine the claim and evidence in your own words.
    a later start may help teenagers
  4. Write the answer.
    Sleep experts say a later start may help teenagers, because their body clocks shift later and a trial showed higher attendance.

Check. The summary keeps the claim and the evidence. ✓

Worked example 5.5.2
Which detail in Source B is least important to a summary? Choose one: the trial had 180 pupils, teenagers need eight to ten hours of sleep or a later start can help.

Method. Test each choice against the sentence or the text.

  1. Read what the question asks for. Decide what the sentence or the text needs.
  2. Test the choice. The number is a useful detail, but the main point is the claim about sleep and start time.
    the trial had 180 pupils fits
  3. Reject the other choices. The sleep range and the claim are the main points of the leaflet.
    teenagers need eight to ten hours of sleep and a later start can help do not fit
  4. Write the answer.
    the trial had 180 pupils

Check. The choice fits the sentence or the text. ✓

Worked example 5.5.3
Why must a summary of Source B include the words "may differ"?

Method. Decide whether a limit is part of the main point.

  1. Find the limit. The leaflet says the results may differ elsewhere.
    the results may differ elsewhere
  2. Decide if it matters. The limit changes how far the claim can be trusted.
    how far the claim can be trusted
  3. Include it. A fair summary keeps the limit.
    to keep the limit on the results
  4. Write the answer.
    to keep the limit on the results

Check. The limit is kept in the summary. ✓

Watch out

Watch out: a summary that leaves out a limit is unfair. Keep the caveats the writer gives.

Exam tip

Exam tip. One sentence: the main claim, the main evidence, and any limit the writer admits.

Exercise 5E  Practice: summarising one source

1
FSummarise the first paragraph of Source B in one sentence.
2
FSummarise the second paragraph of Source B in one sentence.
3
FSummarise Source D in one sentence.
4
FWhich is the main point of Source B? Choose one: a later start can help teenagers sleep and attend, sleep does not matter or alarm clocks are the answer.
5
FCopy the phrase that gives the trial's size.
6
FIn which paragraph does Source B state its limit on the results? Write the number.
7
FWhat does adolescence mean in the phrase "during adolescence"? Write the meaning in your own words.
8
FSummarise Source B in one sentence, keeping its limit.
9
FSummarise Source A in one sentence, keeping its purpose.
10
RExplain why a summary should not copy whole sentences from a source.
11
FWhich sentence is a fair summary of Source D? Choose one: The trial moved the start to 9.15 a.m., attendance rose slightly, and exam marks did not change., The trial was a complete failure. or The school is ending its start times..

Synthesising several sources into one account

Year 9
Synthesise the main ideas of several sources into one account, weighing their reliability (KS3 reading, R6 and R7)
Video lesson: Synthesising several sources into one accountComing soon
Context. A synthesis combines several sources into one account. It does not list them one by one. It says what they agree on, where they differ, and which evidence is strongest. Use exact figures, and say which source each one comes from.

Source B: a leaflet from a sleep charity (original, fictional charity)

1Teenagers need around eight to ten hours of sleep each night.

2Their body clocks shift later during adolescence, so many are alert late at night and tired early in the morning.

3A later start can help. In one trial at a school in another county, attendance rose by four per cent after the start moved from 8.30 to 9.15 a.m.

4That trial had 180 pupils and ran for one term, so the results may differ elsewhere.

Source D: a summary of a school trial (original, fictional school)

1Summary of the trial at Brackenfield School.

2From September, the start for Years 7 to 9 moved from 8.30 a.m. to 9.15 a.m. for one term.

3Attendance for these years rose from 92.1 per cent to 93.0 per cent, and lateness fell by 14 per cent.

4Staff reported no change in exam marks over the term. The governing body will review the trial in July.

Key ideas

  • Synthesis combines main ideas from several sources into one account.
  • Name the source for each piece of evidence, and use exact figures.
  • Weigh the sources: say which evidence is most reliable, and why.
Worked example 5.6.1
Write one sentence that synthesises Sources B and D on attendance.

Method. Find the attendance point in each source, then combine them.

  1. Find B. Source B reports a rise of four per cent in another county.
    attendance rose by four per cent
  2. Find D. Source D reports a rise from 92.1 to 93.0 per cent.
    from 92.1 per cent to 93.0 per cent
  3. Combine. Both show a rise, but the size and the school differ.
    the size and the school differ
  4. Write the answer.
    Both report a rise in attendance, but Source B's rise is four per cent in another school and Source D's is 0.9 points at Brackenfield.

Check. Both attendance figures are used accurately. ✓

Worked example 5.6.2
Which is the best synthesis of Sources B and D on the trial? Choose one: both trials suggest a later start may help, but the evidence is small and the results vary, both trials prove that a later start is always better or both trials show exam marks rose.

Method. Test each choice against the sentence or the text.

  1. Read what the question asks for. Decide what the sentence or the text needs.
  2. Test the choice. The two sources agree on a possible benefit, but they show different sizes of effect and small samples.
    both trials suggest a later start may help, but the evidence is small and the results vary fits
  3. Reject the other choices. Proof of always better is not in either source, and exam marks did not rise in Source D.
    both trials prove that a later start is always better and both trials show exam marks rose do not fit
  4. Write the answer.
    both trials suggest a later start may help, but the evidence is small and the results vary

Check. The choice fits the sentence or the text. ✓

Worked example 5.6.3
Which source gives the more reliable figure on attendance, and why?

Method. Compare what each source measured and how.

  1. Compare the measures. Source D gives two dated figures from one school.
    92.1 per cent
  2. Compare the evidence in B. Source B gives a rise of four per cent in a trial of 180 pupils elsewhere.
    180 pupils
  3. Judge. Source D's measured figures are more reliable for the school it describes.
    Source D
  4. Write the answer.
    Source D, because it reports a measured figure from the school with dates

Check. The judgement compares the two measures. ✓

Watch out

Watch out: a synthesis is not a list. Say what the sources agree on and where they differ.

Exam tip

Exam tip. Start with what the sources agree on, then say where they differ, then judge which evidence is strongest.
