Reading Comprehension Practice Test 2 — Questions and Answers
Question 1: Read the following passage: 'The Amazon rainforest produces approximately 20% of the world's oxygen. However, due to deforestation, an area the size of a football field is lost every minute.' What is the author's primary purpose?
- To describe the types of trees in the Amazon
- To highlight the importance of the Amazon and the threat it faces (Correct answer)
- To encourage tourism to the Amazon region
- To compare the Amazon to other forests
Correct answer: To highlight the importance of the Amazon and the threat it faces
The passage establishes the Amazon's importance (20% of oxygen) and then presents the threat (rapid deforestation), making the purpose to highlight both its value and the danger it faces.
The passage has a two-part structure: first establishing significance (20% of oxygen production) and then revealing a threat (deforestation at an alarming rate). Together, these create urgency — the purpose is to inform readers about both the Amazon's critical importance and the serious threat of deforestation. The 'However' signals a contrast between value and destruction.
Question 2: In the sentence 'The committee reached a consensus after hours of deliberation,' what does 'consensus' most likely mean?
- A heated argument
- A general agreement among all members (Correct answer)
- A decision made by one person
- A postponement of the discussion
Correct answer: A general agreement among all members
After 'hours of deliberation' (discussion), the committee 'reached' something — a consensus is a general agreement that emerges from extended discussion.
Context clues include 'committee' (group decision-making), 'hours of deliberation' (extended discussion), and 'reached' (arrived at an outcome). A consensus is a general agreement among all or most members of a group, typically achieved through discussion and compromise. It's not an argument (A), which would be a problem rather than something 'reached.' It's not one person's decision (C) — that contradicts 'committee.' And it's not a postponement (D) — 'reached' implies a conclusion.
Question 3: A passage describes how a scientist observed that birds near airports had shorter, more rapid alarm calls compared to birds in quiet forests. Which inference is best supported?
- Birds near airports are more intelligent than forest birds
- Urban noise may cause birds to modify their communication patterns (Correct answer)
- Airport birds are a different species than forest birds
- The scientist made an error in their observations
Correct answer: Urban noise may cause birds to modify their communication patterns
The difference in alarm calls between noisy (airport) and quiet (forest) environments suggests that birds adapt their communication to be heard above ambient noise.
The key variable is environmental noise: airports are loud, forests are quiet. The observed difference is in bird calls: shorter and more rapid near airports. The most logical inference connects these: birds near airports have modified their calls to be heard over ambient noise. This is consistent with known research on urban bird song adaptation. Intelligence differences (A) are unsupported. Different species (C) isn't indicated — the comparison implies the same or similar species in different environments. Observer error (D) has no textual support.
Question 4: Read the passage: 'Although Thomas Edison is often credited with inventing the light bulb, he actually improved upon designs by over twenty earlier inventors. His contribution was making the bulb practical and long-lasting enough for commercial use.' What is the main idea?
- Thomas Edison stole other people's ideas
- Edison's main achievement was perfecting the light bulb for practical use, not inventing it from scratch (Correct answer)
- Light bulbs were already perfect before Edison
- Edison was the only person working on electric lighting
Correct answer: Edison's main achievement was perfecting the light bulb for practical use, not inventing it from scratch
The passage corrects a misconception: Edison didn't invent the bulb but improved it for practical use. The main idea is about his real contribution — perfecting existing technology.
The passage uses a corrective structure: 'Although [common belief]... he actually [reality].' The common belief is that Edison invented the light bulb. The reality is that he improved upon twenty earlier designs to make the bulb commercially viable. The main idea is about Edison's true contribution — practical improvement, not original invention. He didn't steal ideas (A) — improving is different from stealing. Bulbs weren't perfect before him (C) — they weren't 'practical' or 'long-lasting.' And he wasn't alone (D) — twenty earlier inventors are mentioned.
Question 5: A passage reads: 'The school cafeteria introduced a salad bar, replaced fried foods with baked alternatives, and added fresh fruit options. Within one semester, student visits to the nurse for stomach complaints decreased by 40%.' What conclusion is best supported?
- Students stopped eating at the cafeteria entirely
- The healthier food options likely contributed to improved student digestive health (Correct answer)
- The school hired a new nurse who diagnosed fewer problems
- Stomach complaints are always caused by fried food
Correct answer: The healthier food options likely contributed to improved student digestive health
The healthier menu changes (salad bar, baked instead of fried, fresh fruit) preceded a decrease in stomach complaints, suggesting the dietary improvements contributed to better digestive health.
The passage establishes a timeline: dietary changes came first, then stomach complaints decreased 40%. The most logical connection is that healthier food options improved digestive health. The word 'likely' in Option B is appropriately cautious — correlation doesn't prove causation, but the temporal relationship supports the contribution. Students didn't stop eating (A) — the passage implies they used the new options. A new nurse (C) is unsupported. And 'always' (D) is too absolute — the passage shows correlation, not universal causation.
Question 6: In the sentence 'The musician's performance was so captivating that the audience sat in complete silence, not wanting to miss a single note,' what does 'captivating' mean?
- Boring and uninteresting
- Extremely attractive and holding attention completely (Correct answer)
- Confusing and difficult to follow
- Loud and overwhelming
Correct answer: Extremely attractive and holding attention completely
The audience's response — sitting in complete silence, not wanting to miss anything — demonstrates they were completely absorbed, which is what captivating means.
The audience's behavior provides the context clue: complete silence and not wanting to miss a single note. This describes total absorption — the performance held their attention completely. 'Captivating' means holding someone's attention irresistibly, as if captured by the experience. A boring performance (A) would produce restlessness, not attentive silence. A confusing one (C) might produce murmuring or distraction. An overwhelming one (D) might cause discomfort. Only a captivating performance produces willing, focused silence.
