1. Which hormone is produced by the thyroid gland?

• A. Insulin
• B. Thyroxine
• C. Adrenaline
• D. Cortisol

Correct answer: B

Rationale: The correct answer is B: Thyroxine. The thyroid gland produces thyroxine, a hormone essential for regulating metabolism. Insulin is produced by the pancreas to regulate blood sugar levels. Adrenaline is produced by the adrenal glands to prepare the body for the 'fight or flight' response. Cortisol is produced by the adrenal cortex in response to stress, not by the thyroid gland.

2. Which of the following sets of words correctly fill in the blanks in the sentence below: We cannot allow the budget cuts to _______ the plans to improve education; the futures of _______ children are at stake.

• A. effect; your
• B. affect; you're
• C. affect; your
• D. effect; you're

Correct answer: C

Rationale: In this sentence, 'affect' is the correct verb meaning 'to influence,' and 'your' is the correct possessive pronoun. Therefore, the sentence should read, 'We cannot allow the budget cuts to affect the plans to improve education; the futures of your children are at stake.' Choice A is incorrect because 'effect' is a noun, not a verb, and 'your' is the correct possessive pronoun. Choice B is incorrect because 'you're' is a contraction for 'you are,' which does not make sense in this context. Choice D is incorrect because 'effect' should be 'affect' as the verb is needed to show influence.

3. Where can you typically find the thesis statement of an essay?

• A. Conclusion
• B. Introduction
• C. Body paragraph
• D. Bibliography

Correct answer: B

Rationale: The thesis statement of an essay is usually located in the introduction. This is where the author establishes the main idea or argument that will be developed throughout the essay. The conclusion (Choice A) summarizes the main points and restates the thesis but does not introduce it. Body paragraphs (Choice C) provide supporting details and arguments, while the bibliography (Choice D) lists the sources used in the essay, not the thesis statement.

4. What is the main idea of the passage?

• A. Manufacturers of dietary supplements must adhere to good manufacturing practices.
• B. The FDA has a specialized program for regulating dietary supplements.
• C. The federal government prosecutes individuals who deceive the public.
• D. The FDA operates under the federal government.

Correct answer: B

Rationale: The main idea of the passage is that the FDA has a specialized program for regulating dietary supplements. The passage explains how the FDA regulates dietary supplements differently from drugs, focusing on the requirements for marketing, good manufacturing practices, monitoring safety, and taking action against unsafe products. Choice A is incorrect because while it mentions good manufacturing practices, it's not the central idea of the passage. Choice C is incorrect as there is no emphasis on prosecuting individuals in the passage. Choice D is incorrect because stating that the FDA is part of the federal government is not the main idea discussed in the passage.

5. Which respiratory structure is responsible for vocalization and sound production?

• A. Trachea
• B. Larynx
• C. Bronchi
• D. Alveoli

Correct answer: B

Rationale: The correct answer is B: Larynx. The larynx, also known as the voice box, is the respiratory structure responsible for vocalization and sound production. It contains the vocal cords, which vibrate as air passes through, producing sound. The trachea (A) connects the larynx to the bronchi. While the trachea serves as the windpipe, it is not directly involved in sound production. Bronchi (C) are airway passages that branch off from the trachea and lead to the lungs, but they are not responsible for vocalization. Alveoli (D) are tiny air sacs in the lungs where gas exchange occurs, but they are not involved in sound production.
