What this dot point is asking
The "how far do the sources support" question is the final and highest-mark part of the case study. It gives you a statement (a view) and asks how far the whole set of sources backs it up. The examiner is testing whether you can use every source, sort them into those that support the view and those that challenge it, weigh how trustworthy they are, and reach a balanced overall judgement. This is the question where all your other skills (inference, comparison, reliability) come together.
The answer
What how far means
"How far" is not a yes or no question. It asks you to measure the degree of support: fully, largely, partly, or hardly. The word "far" is a signal that you must weigh the sources against each other and give a graded answer, not pick a side.
Group the sources: support and challenge
The clearest structure is two groups:
- Sources that support the view. For each, name the source, quote a detail, and explain how it backs the statement.
- Sources that challenge the view. For each, name the source, quote a detail, and explain how it goes against the statement.
Work through every source. Leaving a source out is one of the easiest ways to lose marks, because the question usually says "use all the sources".
Use evidence from each source
Just as in inference, every point needs a specific detail. A table shows numbers; a photograph shows a scene; a written source gives a quote. Pull the exact detail from each source and say what it shows about the statement. Vague claims with no source detail score little.
Weigh reliability where it matters
You do not need to check every source's reliability, but you should comment where it changes the picture. If a source that seems to support the view is actually an advert or a one-sided account, say so: it looks like support, but its purpose makes it less trustworthy. This shows mature handling of evidence.
Reach a balanced judgement
End with a clear "how far" verdict. Count the supporting and challenging sources, but also weigh their quality. A measurable table may count for more than a single complaint. Say whether the sources largely support, partly support, or hardly support the view, and give the reason. Avoid a flat "yes" or "no".
Examples in context
Example 1. How far do sources support that a policy improved racial harmony. A set might mix a positive resident account, a table of mixed-race friendships rising, a complaint about a tense incident, and a glowing government brochure. You would group support (resident, table) against challenge (the incident), discount the brochure as one-sided, and judge that the sources largely support the view with a noted exception. This sits in the managing diversity and cohesion Issue.
Example 2. How far do sources support that globalisation has benefited Singapore. Sources might include a worker praising new jobs, a chart of rising trade, a complaint about higher living costs, and an advert from a multinational. You would weigh the measurable trade chart and the worker's account against the cost-of-living complaint, treat the advert with caution, and reach a balanced how-far verdict. This links to the economic impacts of globalisation.
Try this
Q1. A set of three sources is about whether a new MRT line has reduced traffic. Two sources (a commuter and a table of falling car use) support it; one (a driver complaining roads are still jammed) challenges it. How far do the sources support the view that traffic has fallen? [5 marks]
- Cue. Support group: commuter plus the measurable table. Challenge group: the driver. Judgement: largely supported, because the table gives measurable evidence and only one source disagrees, though some congestion remains.
Q2. Explain why you should comment on the reliability of a source when answering a how-far question. [2 marks]
- Cue. Because a source that looks like support may be one-sided (an advert or a biased account), so noting its purpose stops it from counting fully and makes your judgement more balanced.
Q3. A view states that "the neighbourhood feels safer since the new lighting was installed". One source agrees, one disagrees, and one is a flyer from the company that sold the lights. How would you handle the flyer? [3 marks]
- Cue. Treat it as support in appearance but unreliable in fact: its purpose is to sell the lights, so its praise is one-sided and should be discounted, not counted as strong support.

Original8 marksHow far do the sources support the view that the new park has been good for the neighbourhood? Use all the sources and your own knowledge in your answer. (Assume four sources: Source A, a resident, praises the park as a place where families gather; Source B, a table, shows visitor numbers rising sharply; Source C, an elderly resident, complains about noise late at night; Source D, an advert by the developer, calls the park a complete success.)Show worked answer →
Sources that support the view: Source A supports it, describing the park as a place where "families gather", which shows a social benefit. Source B, the table, supports it too, showing visitor numbers "rising sharply", which suggests the park is popular and well used.
Sources that challenge the view: Source C challenges it, complaining about "noise late at night", which shows the park has created a problem for some residents. Source D appears to support the view by calling the park "a complete success", but as it is an advert by the developer its purpose is to sell, so it is one-sided and should be treated with caution.
Weighing and judgement: most of the trustworthy sources (A and B) support the view that the park has been good, with B giving measurable evidence. The main challenge (C) is genuine but limited to noise affecting some people, and the strongest supporting-sounding source (D) is unreliable. Overall, the sources largely support the view that the park has been good for the neighbourhood, with the qualification that it has caused some noise problems.
What markers reward: clear grouping into support and challenge, evidence from EVERY source, a comment on the reliability of at least one source (the advert), and a balanced final judgement that says how far, not just yes or no.
Original7 marksHow far do the sources support the view that young people in Singapore care about their community? Use all the sources. (Assume three sources: Source E, a student, describes regular volunteering with friends; Source F, a community leader, says many young people stop volunteering after one event; Source G, a photograph, shows a large youth clean-up team at a beach.)Show worked answer →
Sources that support the view: Source E supports it, describing "regular volunteering with friends", which shows commitment to the community. Source G supports it too, showing "a large youth clean-up team", which suggests many young people are willing to give their time.
Sources that challenge the view: Source F challenges it, saying many young people "stop volunteering after one event", which suggests the care is shallow or short-lived for some.
Weighing and judgement: two sources (E and G) suggest young people do care and act, while one (F) warns that the commitment does not always last. The photograph in G is strong evidence of a real event, though it captures only one moment. Overall, the sources mostly support the view that young people care about their community, but with the qualification that this care is not always sustained.
What markers reward: grouping for and against, evidence from all three sources, a note on what a single photograph can and cannot prove, and a clear how-far judgement rather than a flat yes or no.
