Strong comparison answers do more than place two things side by side. They identify a clear comparison point, select relevant information about both sides and explain the similarity, difference or contrast.

1. Unit Purpose

R13: Comparing Information and Ideas develops the ability to compare information, ideas, experiences, people, places and viewpoints accurately and selectively.

EDUSAMBAM principle

Compare the same point. Choose relevant information about both sides, then make the relationship between them clear.

2. Learning Outcomes

3. What Is Comparison?

To compare is to examine two or more things in relation to the same feature or purpose. A comparison may show that things are similar, different or both.

Example

Person A: stays calm during difficulties.

Person B: becomes frustrated when difficulties arise.

Comparison: Both face difficulties, but A responds calmly whereas B reacts with frustration.

4. Comparison vs. Separate Description

Separate descriptionDirect comparison
A enjoys working outdoors. B enjoys working indoors.A prefers outdoor work, whereas B prefers indoor work.
A travelled by train. B travelled by car.A travelled by train, while B travelled by car.

A strong comparison makes the relationship between the two sides visible.

5. Read the Comparison Question Carefully

Before searching for evidence, identify:

Exam focus

If the question asks how two people responded to difficulty, do not compare their clothing, backgrounds or occupations unless those details directly affect their responses.

6. Find the Comparison Point

The comparison point is the feature that both sides have in common as a topic of comparison.

Two thingsPossible comparison point
Two journeysDifficulty, preparation, duration or experience
Two leadersLeadership style, decisions or attitude to problems
Two placesEnvironment, facilities, atmosphere or accessibility
Two projectsAims, methods, results or challenges

7. Similarities

A similarity shows how two things are alike in a relevant way.

Example

Both communities experienced a shortage of water, and both introduced conservation measures to reduce waste.

The comparison is effective because the same issue — water shortage and response — is considered for both communities.

8. Differences

A difference shows how two things are unlike one another in a relevant way.

Example

The first school relied mainly on printed resources, whereas the second used digital materials and online activities.

The difference is focused on the same comparison point: the type of learning resources used.

9. Balanced Comparison

A balanced answer gives attention to both sides. Avoid writing several details about one side and only one vague statement about the other.

UnbalancedBalanced
Three detailed points about A, followed by “B was different.”A is described with relevant evidence and B is described on the same comparison points.

10. Use Comparison Language

Useful language helps make the relationship explicit.

PurposeUseful language
Similarityboth, similarly, likewise, in the same way
Differencewhereas, while, unlike, in contrast
Degreemore, less, greater, lower, considerably
Qualificationalthough, however, despite this

Do not use comparison words mechanically. The information must genuinely show the relationship claimed.

11. Comparing Evidence

When a question requires textual evidence, select details that can be placed meaningfully against each other.

Example

Question: How did the two travellers respond to the unexpected delay?

Traveller A: reorganised the timetable and remained calm.

Traveller B: became impatient and complained.

Comparison: Both were affected by the delay, but A responded by finding a practical solution, whereas B reacted negatively.

12. Compare Ideas, Not Just Facts

Comparison can involve ideas or viewpoints rather than physical details.

Example

One writer presents technology as a tool that increases access to education. Another accepts its benefits but warns that unequal access may create new disadvantages.

The comparison concerns the writers' ideas about the role and effects of technology.

13. Comparing Attitudes

Two people or writers may respond to the same subject differently.

SubjectPerson APerson B
Changewelcomes it as an opportunityviews it cautiously
Riskaccepts some risktries to avoid risk

The strongest answer explains the contrast rather than simply labelling one person “positive” and the other “negative.”

14. Comparing Experiences

When comparing experiences, consider what happened, how each person responded and what the outcome was.

Example

Both hikers became tired during the final stage of the journey. However, one rested before continuing, while the other pushed on without stopping and later struggled to finish.

15. Comparing Causes and Effects

Two situations may have similar outcomes but different causes, or similar causes but different outcomes.

ComparisonExample
Same cause, different effectBoth experienced heavy rain, but one journey was delayed while the other was cancelled.
Different causes, same effectOne school had poor attendance because of distance; another had poor attendance because of unsuitable timings.

16. Comparing Advantages and Disadvantages

When comparing two choices, use the same criteria for each.

Example

Option A: cheaper but slower.

Option B: more expensive but faster.

Comparison: A has a financial advantage, whereas B has a time advantage.

17. Information from Different Paragraphs

A comparison answer may require you to gather evidence from several parts of a passage. Track where each relevant detail appears.

Reading strategy

As you read, mentally mark information for Side A and Side B. Then group details according to comparison points rather than simply following the order in which they appear.

18. Avoid False Comparisons

Do not claim a similarity or difference that the evidence does not support.

Example

If the text says that both people arrived early, it is incorrect to write that one arrived early and the other arrived late simply because their other behaviours were different.

19. Avoid “One-Sided” Answers

A common mistake is to explain one side carefully and then add a short, unsupported statement about the other.

Better approach

For every important comparison point, ask: What does the text show about A? What does it show about B? What is the relationship between them?

20. Worked Cambridge-Style Example

Read and analyse

Text A: “The town park was redesigned with new walking paths, shaded seating and a children's play area. Families began visiting more frequently.”

Text B: “The riverside park kept its original layout but added better lighting and extended its opening hours. Local residents reported using it more often in the evening.”

Question: How were the two parks improved in different ways?

Strong response: Both parks became more useful to visitors, but the improvements were different. The town park was physically redesigned with new paths, shaded seating and a play area, whereas the riverside park kept its original layout and instead improved lighting and extended its opening hours.

Why it works: The answer identifies the common comparison point — improvement for users — then selects relevant details from both texts and directly explains the difference.

21. Common R13 Mistakes

22. Exam Strategy: SAME POINT → BOTH SIDES → RELATIONSHIP

Three-step R13 method

1. SAME POINT: Identify the feature being compared.

2. BOTH SIDES: Select relevant information about each side.

3. RELATIONSHIP: State clearly whether the information shows a similarity, difference or contrast.

23. Practice Task

Read and analyse

Passage A: “The first community garden depended on volunteers who visited every weekend. The gardeners grew vegetables and shared the produce with nearby families.”

Passage B: “The second garden employed a small team of workers during the week. It concentrated on flowers and created a public space where visitors could relax.”

Task: Compare how the two community gardens were organised and used.

24. Final R13 Checklist

Key takeaway

Good comparison is purposeful. Identify the same point, select evidence from both sides, and clearly explain how they are similar or different.
