1. What is the author's purpose in discussing aquatic insects in relation to those that spend their entire lives in the air?

• A. To emphasize the adaptability and complexity of insect life cycles.
• B. To compare aquatic insects with those that remain airborne.
• C. To highlight the unique features of insects that live in both environments.
• D. To question the validity of studying insects that live in only one environment.

Correct answer: A

Rationale: The author's purpose in discussing aquatic insects in relation to those that spend their entire lives in the air is to emphasize the adaptability and complexity of insect life cycles. The author highlights how some insects transition between aquatic and aerial environments, showcasing the diverse strategies and features these insects possess to thrive in different habitats. Choice B is incorrect because the author is not solely comparing aquatic insects with those that remain airborne, but rather exploring their adaptability. Choice C is incorrect as the focus is not on highlighting unique features but on showcasing the transition between environments. Choice D is incorrect as the author is not questioning the validity of studying insects in only one environment but rather demonstrating the fascinating dual-life cycles of certain insects.

2. Which of the following evidence from the passage supports the inference that providing nap rooms at work can improve employee productivity?

• A. In the recent company-wide audits, many employees have reported fatigue at work.
• B. According to a 2008 study, napping for 60 minutes helped improve verbal memory, motor skills, and perceptual learning better than caffeine.
• C. Many successful companies have adopted the practice of work naps, in industries like tech, manufacturing - even NASA!
• D. Starting today, we will be providing a designated nap room in each office building near the gym and cafeteria to help employees take care of their bodies and minds, so they can be happier, healthier, and more productive.

Correct answer: B

Rationale: The correct answer is B because the evidence from the 2008 study mentioned in the passage supports the inference that napping for 60 minutes can improve verbal memory, motor skills, and perceptual learning better than caffeine. This indicates that providing nap rooms at work can lead to improved productivity by enhancing cognitive functions. Choice A talks about the fatigue reported by employees but does not directly link it to productivity improvement. Choice C mentions that many successful companies have adopted the practice of work naps but does not specifically tie it to productivity enhancement. Choice D states the intention to provide nap rooms for employees but does not provide direct evidence of productivity improvement.

3. Which of the following words could most logically replace the underlined word without altering the intent of the sentence?

• A. Shouted
• B. Expressed
• C. Persuaded
• D. Whispered

Correct answer: B

Rationale: In the context provided, the word 'propagated' indicates that Xavier conveyed or expressed his belief to his friends. 'Expressed' is the most suitable synonym here as it aligns with the idea of communicating a belief clearly. The other options, 'shouted,' 'persuaded,' and 'whispered,' do not capture the essence of spreading or communicating an idea, making them incorrect choices.

4. What is the best summary of this passage?

• A. Humans can use coloration and markings on snakes to determine whether they’re venomous.
• B. Animals use coloration to hide from predators.
• C. The scarlet kingsnake and the coral snake have nearly identical markings.
• D. Venomous snakes often have bright markings, although nonvenomous snakes can also mimic those colors.

Correct answer: A

Rationale: The best summary of the passage is that humans can use coloration and markings on snakes to determine whether they're venomous. The passage discusses how snake markings serve the purpose of warning predators and helping humans identify venomous snakes by their bright coloration. Choice B is incorrect because the passage focuses on how coloration helps snakes evade predators rather than hide from them. Choice C is incorrect as it only mentions two specific snakes with similar markings, which is a minor detail compared to the main point of identifying venomous snakes. Choice D is incorrect because it only partially reflects the passage, focusing solely on the relationship between markings and venom in snakes, missing the crucial aspect of human ability to discern venomous snakes based on their coloration.

5. Which statement best details the central idea in this passage?

• A. It discusses insects that transition from water to air during their life cycle.
• B. It explores the field of entomology, particularly focusing on gills.
• C. It explains the mechanism of insects' respiration.
• D. It encourages readers to contribute to insect conservation efforts.

Correct answer: A

Rationale: The correct answer is A because the passage primarily discusses certain insects that spend time in water during their early stages and then transition to an aerial life when they reach adulthood. It highlights how these insects, such as Stoneflies, May-flies, and Dragon-flies, live in water initially and then in the air during their adult stage. This central idea is best captured by choice A. <br> Choice B is incorrect because while the passage mentions gills as a part of the respiratory system of aquatic insects, it does not delve into entomology as a field. Choice C is incorrect as it does not solely focus on defining insect respiration but rather on the transition of certain insects between aquatic and aerial environments. Choice D is incorrect as the passage does not explicitly invite readers to participate in insect preservation efforts; it mainly focuses on describing the life cycle of specific insects.
