A focused Cambridge O Level English Language 1123 unit on identifying similarities, differences and contrasts between information, ideas, experiences and viewpoints in texts.
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.
R13: Comparing Information and Ideas develops the ability to compare information, ideas, experiences, people, places and viewpoints accurately and selectively.
Compare the same point. Choose relevant information about both sides, then make the relationship between them clear.
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.
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.
| Separate description | Direct 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.
Before searching for evidence, identify:
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.
The comparison point is the feature that both sides have in common as a topic of comparison.
| Two things | Possible comparison point |
|---|---|
| Two journeys | Difficulty, preparation, duration or experience |
| Two leaders | Leadership style, decisions or attitude to problems |
| Two places | Environment, facilities, atmosphere or accessibility |
| Two projects | Aims, methods, results or challenges |
A similarity shows how two things are alike in a relevant way.
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.
A difference shows how two things are unlike one another in a relevant way.
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.
A balanced answer gives attention to both sides. Avoid writing several details about one side and only one vague statement about the other.
| Unbalanced | Balanced |
|---|---|
| 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. |
Useful language helps make the relationship explicit.
| Purpose | Useful language |
|---|---|
| Similarity | both, similarly, likewise, in the same way |
| Difference | whereas, while, unlike, in contrast |
| Degree | more, less, greater, lower, considerably |
| Qualification | although, however, despite this |
Do not use comparison words mechanically. The information must genuinely show the relationship claimed.
When a question requires textual evidence, select details that can be placed meaningfully against each other.
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.
Comparison can involve ideas or viewpoints rather than physical details.
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.
Two people or writers may respond to the same subject differently.
| Subject | Person A | Person B |
|---|---|---|
| Change | welcomes it as an opportunity | views it cautiously |
| Risk | accepts some risk | tries to avoid risk |
The strongest answer explains the contrast rather than simply labelling one person “positive” and the other “negative.”
When comparing experiences, consider what happened, how each person responded and what the outcome was.
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.
Two situations may have similar outcomes but different causes, or similar causes but different outcomes.
| Comparison | Example |
|---|---|
| Same cause, different effect | Both experienced heavy rain, but one journey was delayed while the other was cancelled. |
| Different causes, same effect | One school had poor attendance because of distance; another had poor attendance because of unsuitable timings. |
When comparing two choices, use the same criteria for each.
Option A: cheaper but slower.
Option B: more expensive but faster.
Comparison: A has a financial advantage, whereas B has a time advantage.
A comparison answer may require you to gather evidence from several parts of a passage. Track where each relevant detail appears.
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.
Do not claim a similarity or difference that the evidence does not support.
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.
A common mistake is to explain one side carefully and then add a short, unsupported statement about the other.
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?
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.
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.
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.
Planning prompts:
Good comparison is purposeful. Identify the same point, select evidence from both sides, and clearly explain how they are similar or different.
