1. What is the definition of the word 'fry' as it appears in the passage?

• A. Fry eggs that have been fertilized.
• B. Young fish capable of feeding themselves.
• C. A place where larvae are kept safe from predators.
• D. Fish prepared to be fried in oil.

Correct answer: B

Rationale: The correct answer is B: 'Young fish capable of feeding themselves.' In the provided extract, 'fry' refers to the young fish that are hatched out and are old enough to take charge of themselves. Choice A is incorrect as it refers to a different context of 'fry.' Choice C is incorrect as it describes a location rather than the meaning of 'fry.' Choice D is also incorrect as it provides a definition of 'fry' related to cooking, which is not the intended meaning in the passage.

2. What term describes the phenomenon of two waves canceling each other out when they meet?

• A. Refraction
• B. Diffraction
• C. Destructive interference
• D. Constructive interference

Correct answer: C

Rationale: Destructive interference is the term used to describe the phenomenon when two waves meet and their amplitudes are such that they cancel each other out, resulting in a wave with a smaller amplitude or no wave at all. This cancellation effect occurs due to the waves being out of phase. This is in contrast to constructive interference, where two waves combine to produce a wave with a larger amplitude. Refraction is the bending of waves as they pass through different mediums, such as light passing through glass, while diffraction is the bending of waves around obstacles or through openings. In this case, the concept described in the question specifically aligns with destructive interference, making it the correct answer.

3. Which of these descriptions provides the most detailed and objective support for the claim that drinking and driving is unsafe?

• A. A dramatized television commercial reenacting a fatal accident.
• B. The Department of Transportation's press release noting the deployment of additional patrol units.
• C. Congressional written testimony on drinking incidents.
• D. A highway bulletin warning of penalties for drinking and driving.

Correct answer: C

Rationale: Congressional written testimony on drinking incidents provides the most detailed and factual data on the subject, making it the most objective support for the claim that drinking and driving is unsafe. Choice A, the dramatized television commercial, may be emotionally impactful but lacks detailed data. Choice B, the Department of Transportation's press release, focuses on enforcement actions rather than detailed information on the dangers. Choice D, the highway bulletin warning of penalties, emphasizes consequences rather than providing detailed support for the claim.

4. Express 18/5 as a reduced mixed number.

• A. 3 3/5
• B. 3 1/15
• C. 3 1/18
• D. 3 1/54

Correct answer: A

Rationale: 18/5 = 3 with a remainder of 3, so it is 3 3/5. 3 1/15 is equivalent to 46/15 which is greater than 18/5 3 1/18 converts to 55/18 which is also greater than 18/5 3 1/54 converts to 163/54

5. Which hormone stimulates the release of calcium from bones and increases blood calcium levels?

• A. Parathyroid hormone (PTH)
• B. Calcitonin
• C. Growth hormone
• D. Testosterone

Correct answer: A

Rationale: Parathyroid hormone (PTH) is the correct answer. PTH stimulates the release of calcium from bones, leading to increased blood calcium levels. It acts on the bones to release calcium into the bloodstream, facilitates the kidneys' reabsorption of calcium, and triggers vitamin D activation to boost calcium absorption from the intestines. Choice B, Calcitonin, is incorrect as it works in opposition to PTH by decreasing blood calcium levels through inhibiting calcium release from bones. Choices C and D, Growth hormone and Testosterone, are not directly involved in calcium homeostasis and do not regulate blood calcium levels through bone calcium release mechanisms.
