How to compare the themes and ideas of two texts
TEAS 7 outline: Compare and contrast themes within or across texts
- A topic is a word or short phrase; a theme is a full sentence.
- Two texts can share a topic but have different themes or opinions.
- Sort ideas into three groups: both say, only Passage 1, only Passage 2.
- A both-agree answer must be supported by both passages, not just one.
- Who wrote each text often explains why their views differ.
Key facts
- A topic is the subject in a word or short phrase; a theme is the idea a text develops about that subject, stated as a full sentence.
- Two texts can share a topic and still have different themes or opinions.
- Comparing means finding similarities; contrasting means finding differences on the same point.

- An answer about what both authors agree on must be supported by both passages, not just one.
- Compare signals include similarly, likewise, both and also; contrast signals include however, in contrast, on the other hand, but and unlike.
- Check perspective too: who wrote each text (a manager, a worker, a parent) often explains why their views differ.

Passage 1: From a clinic manager's newsletter column
Last March, our family clinic let staff choose four 10-hour shifts instead of five 8-hour shifts. Nine of our twelve medical assistants signed up. Since then, sick calls have dropped, and two people who had planned to leave told me they are staying. A full extra day off each week gives people time to rest, see their own doctors, and come back ready to work. I believe more clinics should offer this schedule.
Passage 2: From a letter by a medical assistant at the same clinic
I was glad to try the four-day schedule, and I do love my Fridays. But a 10-hour shift that starts at 7 a.m. means I leave home before my son's day care opens, so I pay a neighbor to cover the gap. By the last hour of a long day, I also notice that I am slower and less patient. The schedule works well for some of my coworkers, and I am grateful that it was optional. Any clinic that copies our plan should keep it a choice, not a requirement.
Which choice states a theme of Passage 1 rather than only its topic or a detail?
Correct answer: B.
A topic names a subject in a word or phrase, while a theme is the idea the text develops about that subject, stated as a full sentence. Passage 1's details (fewer sick calls, staff staying, time to rest) all build toward the idea that extra days off make for healthier, steadier staff. A single fact is too narrow to be a theme, and an idea from the other passage does not describe Passage 1.
A This is the topic: it names the subject but makes no point about it.
B Correct: this full-sentence idea is what Passage 1's details about rest, sick calls, and staff staying all support.
C This is a single supporting detail from Passage 1, too narrow to be its central message.
D This idea comes from Passage 2, where the author describes leaving before day care opens.

Each part starts with its main idea. Open a part when you want the details.
The short answer: A topic is what a text is about, in a word or short phrase. A theme is the idea the text develops about that topic, stated as a full sentence. To compare two passages, note each one's gist and stance, then sort ideas into three groups: what both say, what only Passage 1 says, and what only Passage 2 says.
1 What is the difference between a topic and a theme?A topic names what a text is about, while a theme says something about it. 1 min
A topic names what a text is about, while a theme says something about it. The topic fits in a word or short phrase. The theme is the idea the text develops about that topic, so it needs a full sentence.
| Topic (a label) | A theme a text might develop (a full sentence) |
|---|---|
| Night shifts | Working nights can strain sleep and family life. |
| Patient handoffs | Clear handoffs protect patients from small errors. |
| Exercise | Staying active is easier when it fits into daily routines. |
Quick test: if your answer has no verb and makes no point, it is a topic, not a theme.
2 How do you compare two passages quickly?Give each passage a short gist and stance before you look at any answer choices. 1 min
Give each passage a short gist and stance before you look at any answer choices. Then sort the ideas into three groups.
- Passage 1: write its gist and stance in a few words (for example, "four-day week, for it").
- Passage 2: do the same.
- Shared topic: confirm both are about the same subject.
- Overlap test: list what both say, what only Passage 1 says, and what only Passage 2 says.
- Match the question: "both agree" answers come from the overlap; "differ" answers need two different views on the same point.
3 What does that look like on a real pair?Work the overlap test on two short original texts about the same change at work. 1 min
Work the overlap test on two short original texts about the same change at work.
Passage 1 (a hospital wellness director): Our new standing desks have been a hit. Staff say they feel less stiff by the end of the day, and I hope every office will have them soon.
Passage 2 (a medical coder): I like having the option to stand, and my back aches less in the afternoon. Standing all day, though, made my feet sore, so I now switch back and forth every hour.
| Both say | Only Passage 1 | Only Passage 2 |
|---|---|---|
| Standing desks ease some aches | Wants them in every office | Standing all day has a cost |
| Having the desks is positive | Speaks for staff as a group | Recommends switching hourly |
A both-agree answer is "standing desks can ease some physical discomfort." A difference is that Passage 2 names a drawback that Passage 1 never mentions.
4 Which signal words help?Signal words tell you whether an author is adding a similar idea or turning to a different one. 1 min
Signal words tell you whether an author is adding a similar idea or turning to a different one.
| Similar | Different |
|---|---|
| similarly, likewise, both, also, in the same way | however, in contrast, on the other hand, but, unlike, though |
Also notice who wrote each passage. A manager and a worker can watch the same change and weigh it differently.
5 Which wrong answers look most tempting?The most tempting trap is a choice that is true for one passage but not the other. 1 min
The most tempting trap is a choice that is true for one passage but not the other.
- Half right: fits Passage 1 only, but the question asks what both believe.
- Swapped sides: gives one author's point to the other author.
- Topic, not theme: a bare label like "standing desks."
- Detail, not theme: one fact, too narrow to be the main message.
Common mistakes
The traps students fall into most. Read these before you practice.
Watch out: Half right: a choice that is true of one passage but not the other is wrong for a both-agree question.
Watch out: Same topic, not same view: two texts about the same subject do not automatically agree.
Watch out: A topic, not a theme: a word or phrase such as "workplace stress" names the subject but says nothing about it.
Watch out: A detail, not a theme: one fact from the passage is too narrow to be its central message.
Watch out: Swapped sides: a choice that gives Passage 1's point to Passage 2, or the reverse.
How to remember it
Think of two overlapping circles, with the shared ideas in the middle and each passage's own ideas on its side. "Both" questions live in the middle, and "differ" questions live on the sides.
Self-check:
- Turn the topic "hand hygiene" into a theme sentence.
- In the standing-desk pair, name one idea that belongs only to Passage 2.
- Write one both-agree statement for the pair, then check it against each passage separately.
