- The passage explains the feeling of déjà vu by stating that the brain...
Answer: misidentifies a new experience as a past one.
The correct answer is B. The passage says, "a new, incoming experience is incorrectly marked by the brain as an old memory," which directly supports this choice. A is a common folk belief but is not mentioned in the passage. C is directly contradicted by the statement that it is "not a sign of a serious problem." D is incorrect; the brain is processing information incorrectly, not stopping.
- According to the passage, which detail specifically explains why urban farming helps reduce environmental impact beyond just producing food locally?
Answer: Urban farms create green spaces that filter air pollution and reduce urban heat islands
The correct answer is B. The passage states that urban farms 'create green spaces that help filter air pollution and reduce urban heat islands,' which describes an environmental benefit beyond food production. While A and D mention environmental benefits, they relate directly to food production efficiency. C describes techniques but not their environmental impact.
- The passage explains that cities experience higher temperatures than rural areas due to which combination of urban characteristics?
Answer: Heat-absorbing surfaces, reduced plant-based cooling, and architectural barriers to air circulation
The correct answer is A. The passage identifies three main structural factors: dark surfaces that absorb/retain heat, lack of vegetation reducing evapotranspiration cooling, and urban geometry that traps heat and reduces wind circulation. B focuses mainly on human activities rather than urban structure. C mentions mitigation strategies rather than causes. D mixes causes with solutions and doesn't capture the circulation/geometry aspect.
- What is one detail the passage provides to show the importance of photosynthesis?
Answer: It generates the oxygen that many animals need to live.
The correct answer is C. The passage highlights the importance of photosynthesis by stating it "produces the air we breathe." A and D describe parts of the process but not its importance to other life. B describes the importance to the plant itself, but C describes its broader importance, which is the focus of the sentence about its significance.
- Based on the passage, what factor determined the fluctuation in Silk Road trade activity over time?
Answer: The level of political stability and taxation policies imposed by controlling empires
The correct answer is B. The passage explicitly states that 'the route's success depended heavily on political stability, and trade declined significantly during periods of warfare or when empires imposed heavy taxes on merchants.' A focuses only on goods availability, which isn't mentioned as a limiting factor. C mentions weather, which isn't discussed. D refers to religious texts, but these were consequences of trade, not determinants of trade volume.
- According to the passage, scientists use wading bird populations as an ecosystem health indicator because these birds have what specific requirement?
Answer: They require specific water depths and timing conditions for successful breeding cycles
When you encounter reading questions that ask "according to the passage," you need to find the exact information stated in the text, not make inferences or draw from outside knowledge. These questions test your ability to locate and identify specific details.
The passage explicitly states that scientists use wading bird populations as ecosystem health indicators "because these birds require specific water depths and timing for successful breeding." This directly supports answer C, which captures both the water depth requirement and the timing element mentioned in the text.
Let's examine why the other options are incorrect. Answer A mentions phosphorus contamination and algae growth, which the passage does discuss as water quality issues, but these aren't given as the reason scientists monitor wading birds specifically. Answer B refers to seasonal sheet flow patterns and dry periods, which are important to the overall ecosystem but again aren't cited as the specific reason for monitoring bird populations. Answer D mentions undisturbed wetland habitats, which sounds reasonable but isn't the explanation provided in the passage for why these birds serve as indicators.
Each wrong answer contains information that appears elsewhere in the passage, making them tempting distractors. However, they don't answer the specific question about why scientists use wading birds as indicators.
For reading comprehension success, always return to the passage to verify your answer. Look for signal words like "because," "since," or "due to" that indicate cause-and-effect relationships, and match the exact reasoning provided in the text rather than choosing answers that seem generally related to the topic.
- The passage identifies which specific concern related to how AI diagnostic systems are developed and trained?
Answer: The possibility of algorithmic bias when training data lacks sufficient diversity across demographic groups
The correct answer is B. The passage specifically mentions 'algorithmic bias, where AI systems may perform less accurately for certain demographic groups if the training data was not sufficiently diverse.' A refers to over-reliance concerns but not training issues. C mentions integration but not training-specific problems. D contradicts the passage, which states AI often exceeds human accuracy.
- What is one detail the passage gives to show Silas's dedication to his job?
Answer: He cleaned the lighthouse's main lens every day.
The correct answer is C. The passage gives the specific, daily action: "He polished the great lens daily." This is a direct detail showing his dedication. A shows experience, but not necessarily active dedication. B is not stated in the passage. D describes the result of his work, not the action that demonstrates his dedication.
- What detail from the passage supports the idea that the market was a lively place?
Answer: Many different languages could be heard at once.
The correct answer is B. The phrase "the sound of a dozen languages mingling" is a specific detail that contributes to the overall sense of a busy, energetic, and lively market. A, C, and D are all details from the passage, but they describe a specific stall, the narrator's actions, or an object, not the overall atmosphere of the market.
- The passage supports the idea that cities are attractive by stating that they...
Answer: provide access to services that are hard to find elsewhere.
The correct answer is B. The passage says cities provide "superior access to specialized services...which can be scarce in rural regions." A and C are not mentioned. D is an overstatement; the passage says cities offer "more jobs," not that they "guarantee" a job for everyone.
- The passage explains that echolocation helps bats to...
Answer: find their way and catch food at night.
The correct answer is C. The passage states that echolocation allows bats to "navigate and locate insects," which directly corresponds to finding their way and catching food. A is incorrect because echolocation is based on sound, not sight. B and D are not mentioned as functions of echolocation in this passage.
- The passage indicates that code-switching behavior is influenced by which combination of factors?
Answer: Linguistic rules, social context, and the formality level of the communication setting
The correct answer is A. The passage states that code-switching 'follows specific linguistic and social rules' and provides examples showing how it varies based on formality (informal family settings vs. formal professional environments). B incorrectly suggests cognitive development drives the behavior. C and D mention some relevant factors but miss the key linguistic rules component.
- According to the passage, one reason people procrastinate is to...
Answer: avoid feeling unpleasant emotions for a short time.
The correct answer is C. The passage explains that procrastination is a "coping mechanism for dealing with negative feelings" and that it provides "temporary relief from these unpleasant emotions." A, B, and D are common excuses for procrastination, but they are not the psychological reason provided in the text.
- The passage indicates that developing practical biomimetic technologies is challenging because natural systems possess which characteristic?
Answer: They involve multiple interacting factors that scientists must isolate and simplify for engineering applications
Reading comprehension questions about supporting details require you to identify specific information that directly answers the question based on what's explicitly stated in the passage.
The passage clearly explains why biomimetic technology development is challenging in its final sentence: "translating biological mechanisms into practical applications often requires years of research, as natural systems are typically much more complex than their engineering applications, involving multiple interacting factors that scientists must isolate and simplify." This directly supports answer choice C, which captures the core difficulty—natural systems have multiple interacting factors that must be isolated and simplified for engineering use.
Choice A focuses on manufacturing difficulties with microscopic structures, but the passage doesn't emphasize manufacturing challenges as the primary obstacle. While some examples mention microscopic features, this isn't identified as the main challenge. Choice B mentions research time and molecular attractions, but the passage indicates the time requirement stems from complexity, not specifically from understanding molecular mechanisms. Choice D suggests environmental conditions are the issue, but the passage doesn't discuss environmental limitations or replication problems.
The key distinction is that C identifies the fundamental nature of the challenge (complexity requiring simplification), while the other choices focus on more specific technical aspects that aren't highlighted as the primary difficulty.
When answering reading comprehension questions about why something is challenging or difficult, look for statements that directly explain the cause of the problem. Often these appear near the end of passages as concluding observations, and they typically use words like "because," "as," or "since" to signal causal relationships.
- According to the passage, the clownfish contributes to the anemone's health through which specific mechanisms mentioned?
Answer: Providing fertilizer through waste, defending against harmful fish, and improving oxygen circulation through movement
The correct answer is A. The passage explicitly states that clownfish provide fertilizer through waste products, defend anemones from fish that might damage tentacles, and that their movements help circulate water for oxygen flow. B incorrectly suggests clownfish share their mucus coating. C mentions attracting other species and maintaining stinging ability, which aren't mentioned. D incorrectly includes helping with reproduction.
- The passage supports the idea that Gothic buildings were tall by mentioning the use of...
Answer: arches that directed building weight downwards effectively.
The correct answer is B. The passage states that the "pointed arch...could support more weight," which allowed for taller walls. This is a way of saying it directed weight more effectively. A and C are directly contradicted; the passage says innovations allowed for THINNER walls and LARGER windows. D is also contradicted, as the pointed arch is presented as an improvement over the rounded arch.
- According to the passage, the placebo effect provides evidence for the idea that...
Answer: a person's thoughts can influence their physical health.
The correct answer is B. The passage says the placebo effect "demonstrates the powerful connection between the mind and body," which supports the idea that thoughts (belief) can influence health. A is an exaggeration not supported by the text. C is a possible outcome of a trial but not what the effect itself demonstrates. D is a conclusion not supported by the passage.
- According to the passage, one reason a chameleon changes its color is to...
Answer: control its internal body temperature.
The correct answer is C. The passage states that color change is used for "regulating body temperature" and gives the example of turning "darker to absorb more heat." A is incorrect because the passage says camouflage is a "secondary benefit, not the primary driver." B and D are not mentioned in the passage as reasons for color change.
- The author supports the claim that the printing press was a revolutionary invention by noting that it...
Answer: enabled information to be shared widely and rapidly.
The correct answer is D. The passage supports this by stating books could be produced "quickly" and that ideas could "spread...with unprecedented speed." A is a fact but doesn't explain the revolutionary impact. B is an exaggeration; the passage says books were made "cheaply," not free. C is a possible inference but not explicitly stated as the main use.
- What is one specific method mentioned in the passage that Impressionist painters used?
Answer: Using noticeable, short strokes of paint.
The correct answer is C. The passage states that a key technique was "applying paint in small, thin, yet visible brushstrokes," which is paraphrased in this option. B is the opposite of what the passage states Impressionists did. A and D are not mentioned in the passage as techniques used by Impressionists.
