1. Which statement is not a detail from the passage?

• A. Promoters of dietary supplements can make any claims that are supported by research.
• B. GMP requirements for large manufacturers went into effect in 2008.
• C. The FDA regulates dietary supplements in the same way as prescription medications.
• D. Consumers should research supplement claims before making a purchase.

Correct answer: A

Rationale: The statement "Promoters of dietary supplements can make any claims that are supported by research" is not a detail from the passage. The passage mentions that manufacturers, not promoters, can make claims supported by research. The primary focus is on the regulations and manufacturing standards for dietary supplements. Choice B is a detail from the passage as it mentions the GMP requirements for large manufacturers going into effect in 2008. Choice C is incorrect as the passage states that FDA regulations for dietary supplements are not the same as those for prescription medications. Choice D is also supported by the passage, emphasizing that consumers should research supplement claims before making a purchase to ensure accuracy and safety.

2. Which of the following sentences indicates the end of a sequence?

• A. Our ultimate objective was to find a quality coat at an affordable price.
• B. We chose this particular restaurant because of its outdoor seating.
• C. Finally, we were able to settle in to enjoy the movie.
• D. Initially, it seemed unlikely that we’d be able to keep the puppy.

Correct answer: C

Rationale: The sentence 'Finally, we were able to settle in to enjoy the movie.' indicates the completion or conclusion of a sequence of events. The word 'finally' signals that something has been achieved or reached at the end of a series of actions or events. Choices A, B, and D do not indicate the end of a sequence but rather express different points within a series of events or actions.

3. Which of the following events occurred fourth on the timeline?

• A. Helped found the National Geographic Society
• B. Developed a metal detector
• C. Moved to Canada
• D. Started a school for the deaf

Correct answer: D

Rationale: The event that occurred fourth on the timeline was starting a school for the deaf. Looking at the provided extract, we can see that the order is significant when discussing a timeline. Out of the given events, founding a school for the deaf would come fourth in chronological order. 'Helped found National Geographic Society,' 'Developed a metal detector,' and 'Moved to Canada' would precede starting a school for the deaf in a chronological timeline, making them incorrect choices.

4. Which neurotransmitter is associated with mood, sleep, and memory?

• A. Dopamine
• B. Serotonin
• C. Acetylcholine
• D. Glutamate

Correct answer: B

Rationale: Serotonin is a neurotransmitter that is associated with regulating mood, sleep, and memory. It plays a crucial role in maintaining emotional balance and is often a target in treating mood disorders like depression and anxiety. Serotonin also helps regulate sleep patterns and is connected to memory function. Dopamine (choice A) is more commonly linked to reward, motivation, and movement. Acetylcholine (choice C) is involved in muscle control and memory. Glutamate (choice D) is a major excitatory neurotransmitter in the brain but is not primarily associated with mood, sleep, and memory.

5. As a water wave approaches a shallow beach, what happens to its speed, wavelength, and frequency?

• A. Speed increases, wavelength decreases, frequency increases.
• B. Speed decreases, wavelength decreases, frequency remains the same.
• C. Speed increases, wavelength increases, frequency decreases.
• D. Speed, wavelength, and frequency remain the same.

Correct answer: B

Rationale: As a water wave approaches a shallow beach, the speed of the wave decreases due to the change in medium from deep to shallow water. According to the wave equation (speed = frequency x wavelength), if the speed decreases and the frequency remains the same, the wavelength must also decrease to maintain the equation balanced. This phenomenon occurs due to the wavefronts being slowed down by the shallower water, causing the wavelength to decrease while the frequency remains constant. Choice A is incorrect as the speed of the wave decreases in shallow water. Choice C is incorrect because the speed increases in deep water, not in shallow water. Choice D is incorrect as all the wave characteristics change when moving from deep to shallow water.
