1. What is the main idea of the second paragraph?

Correct answer: C

Rationale: The main idea of the second paragraph is that confirming and disconfirming evidence can affect hypotheses differently, as stated in the passage - 'Single pieces of evidence then, seem to affect a given hypothesis in radically different ways.' Choice A is incorrect because the paragraph discusses how single pieces of evidence affect hypotheses, not that one hairy monkey proves a hypothesis. Choice B is incorrect as the paragraph focuses on the different effects of evidence on hypotheses, rather than its ability to confirm and disconfirm simultaneously. Choice D is incorrect as the paragraph does not primarily discuss the scientific method's failings but rather the impact of evidence on hypotheses.

2. Which sentence demonstrates correct use of the apostrophe?

Correct answer: C

Rationale: Choice C, 'The dog's tail wagged,' is the correct use of the apostrophe to show possession. In this sentence, the apostrophe is used correctly to indicate that the tail belongs to the dog. Choice A is incorrect as 'it's' is a contraction of 'it is' or 'it has,' not possessive. Choice B is also incorrect as 'Its' should be 'It's' to mean 'It is' or 'It has.' Choice D is incorrect as 'Its'' is grammatically incorrect; the correct form would be 'It's' if it were a contraction or 'Its' if it indicated possession without an apostrophe.

3. A scientist wants to measure how far a person can run in 30 minutes. Which of the following units should be used to record this measurement as a small number?

Correct answer: B

Rationale: Kilometers are commonly used for shorter distances and would provide a small and practical number to measure distance in this context. Gigameters, Megameters, and Terameters are much larger units of measurement and would result in very large numbers, making them impractical for measuring the distance a person can run in 30 minutes. Therefore, the correct choice is Kilometers as it is a suitable unit for measuring such distances within a reasonable range.

4. Which vitamin plays a vital role in immune function?

Correct answer: C

Rationale: Vitamin D is the correct answer. It plays a vital role in immune function by regulating the immune system and enhancing the pathogen-fighting effects of monocytes and macrophages. Deficiency in Vitamin D has been linked to increased susceptibility to infections and autoimmune diseases, highlighting its importance in maintaining a healthy immune response. Vitamin A (Choice A) is essential for vision and skin health but is not primarily known for its role in immune function. Vitamin B12 (Choice B) is important for red blood cell formation and neurological function, not specifically immune function. Vitamin E (Choice D) acts as an antioxidant and is beneficial for skin health and cell function, but it is not primarily associated with immune system support.

5. What is the part of speech of the word 'exhaustive' in the sentence: 'Investigators conducted an exhaustive inquiry into the accusations of corruption'?

Correct answer: D

Rationale: The word 'exhaustive' is an adjective in this sentence. Adjectives modify nouns, and in this case, 'exhaustive' is describing the noun 'inquiry.' A noun, verb, or adverb would not be appropriate here. A noun is a person, place, thing, or idea, which 'exhaustive' is not. A verb is an action word, and 'exhaustive' is not functioning as a verb in this sentence. An adverb typically modifies a verb, adjective, or another adverb, but 'exhaustive' is not serving this function in the sentence provided. Therefore, the correct answer is 'D: Adjective.'
