CAEL Reading: Identifying Main Ideas 2 — Questions and Answers
Question 1: A paragraph begins: 'Urban green spaces provide numerous psychological benefits to city residents.' The rest of the paragraph lists research studies on stress reduction, mood improvement, and cognitive restoration. What is the main idea?
- Urban green spaces improve the psychological well-being of city residents. (Correct answer)
- Research studies are the best way to measure mood improvement.
- Cities need more parks to reduce overcrowding.
- Cognitive restoration is the most important benefit of nature.
Correct answer: Urban green spaces improve the psychological well-being of city residents.
The opening sentence states the central claim, and all supporting details reinforce it.
Question 2: Which strategy best helps a CAEL reader distinguish the main idea from supporting details?
- Identifying the idea that all other sentences explain or justify. (Correct answer)
- Choosing the sentence with the most statistics.
- Selecting the longest sentence in the paragraph.
- Focusing on transitional words like 'however' and 'therefore'.
Correct answer: Identifying the idea that all other sentences explain or justify.
The main idea is the claim that supporting sentences elaborate on, not necessarily the longest or most data-rich sentence.
Question 3: A passage discusses how climate change affects Arctic ice, sea levels, and global weather patterns. The concluding sentence states: 'These cascading effects illustrate the far-reaching consequences of climate change.' Where is the main idea located?
- In the concluding sentence, which synthesizes the passage's content. (Correct answer)
- In the sentence about Arctic ice, as it is mentioned first.
- In the sentence about sea levels, as it is the most measurable effect.
- There is no main idea because the passage covers multiple topics.
Correct answer: In the concluding sentence, which synthesizes the passage's content.
A concluding main idea sentence wraps up all supporting details into one overarching claim.
Question 4: An academic article's abstract states: 'This study examines the impact of sleep deprivation on university students' academic performance.' The body discusses memory, concentration, and grades. What is the main idea of the article?
- Sleep deprivation negatively affects how well university students perform academically. (Correct answer)
- University students do not get enough sleep during exam periods.
- Memory is the cognitive function most harmed by lack of sleep.
- Grades are the best measure of a student's academic performance.
Correct answer: Sleep deprivation negatively affects how well university students perform academically.
The abstract's thesis sentence frames the entire article's central argument.
Question 5: A passage contains these sentences: (1) Volunteers built 20 new homes. (2) Food banks received record donations. (3) Community members organized free tutoring programs. (4) The disaster brought out remarkable generosity in the town. Which sentence is the main idea?
- Sentence 4, because it makes a general claim the others support. (Correct answer)
- Sentence 1, because it gives the most concrete fact.
- Sentence 2, because donations are the most significant response.
- Sentence 3, because education has long-term value.
Correct answer: Sentence 4, because it makes a general claim the others support.
The most general statement that summarizes what the specific examples illustrate is the main idea.
Question 6: In a CAEL reading passage, a student finds one idea repeated in different words across multiple paragraphs. What does this repetition most likely signal?
- That repeated idea is probably the text's central main idea. (Correct answer)
- The author made an error by being redundant.
- Each repeated version is a separate, equally important main idea.
- The passage has no clear main idea because it is repetitive.
Correct answer: That repeated idea is probably the text's central main idea.
Authors often restate the main idea in different forms to reinforce and develop their central argument.
Question 7: A paragraph reads: 'Although some critics argue that social media harms teen mental health, others point to its role in building supportive communities, enabling activism, and reducing isolation for marginalized youth.' What is the main idea?

- Social media is harmful to teen mental health according to critics.
- Teenagers use social media primarily for activism.
- Marginalized youth are the only group who benefit from social media.
Correct answer: Social media can benefit teenagers by fostering community, activism, and connection.
The paragraph concedes criticism but pivots to argue for social media's positive roles, making that the main point.
A paragraph begins: 'Urban green spaces provide numerous psychological benefits to city residents.' The rest of the paragraph lists research studies on stress reduction, mood improvement, and cognitive restoration.
