Correct Answer: A

Rationale: The correct answer is A: 'To inform, entertain, or persuade readers.' Nonfiction writing aims to provide factual information (inform), engage the audience (entertain), or influence their opinions (persuade). Choice B is incorrect because informing usually takes precedence over entertaining in nonfiction. Choice C is incorrect as the primary goal is not to convince readers they're wrong but rather to present information or arguments. Choice D is incorrect as there are clear purposes for nonfiction writing.

Correct Answer: D

Rationale: Jorgen should go to the 500 section of the library, which is dedicated to science and mathematics. The sieve of Eratosthenes is a mathematical concept, so current applications and research related to it would be found in this section. Choice A (0) is incorrect as it is for general works. Choice B (100) is for philosophy and psychology, which are unrelated to mathematics. Choice C (400) is for languages, not mathematics.

Correct Answer: A

Rationale: The correct answer is 'Plebeian' as it represents the common people, which aligns closely with the definition of a 'working man.' 'Viscount' refers to a nobleman ranking above a baron but below an earl. 'Entrepreneur' is a person who organizes and operates a business, typically taking financial risks in the hope of profit. 'Bourgeois' relates to the middle class, typically with reference to its perceived materialistic values or conventional attitudes.

Correct Answer: A

Rationale: The passage uses a cause and effect order to explain the reasons for the cafe's lack of success. It presents causes (higher prices and early closure) first, followed by their effects (students unable to afford food and beverages, students going elsewhere). This structure helps readers understand the relationship between the causes and their resulting effects. Choice B, 'Compare and contrast order,' is incorrect as the passage does not focus on comparing different aspects or contrasting ideas. Choice C, 'Spatial order,' is incorrect as it does not describe physical locations or arrangements. Choice D, 'Time order,' is incorrect as the passage does not primarily follow a chronological sequence of events.

Correct Answer: D

Rationale: The final comment in the passage indicates that Mr. Utterson intends to keep searching for Mr. Hyde, showing his determination. The passage describes how Mr. Utterson is troubled by questions about Hyde, engaging not just his intellect but also his imagination. Despite the lack of information obtained from Lanyon, Mr. Utterson continues to ponder the problem late into the night, suggesting his commitment to uncovering the mystery. Choices A, B, and C are incorrect because there is no indication in the passage that the speaker is considering a name change, experiencing an identity crisis, or mistakenly looking for the wrong person. The passage focuses on Mr. Utterson's persistent search for Hyde, emphasizing his unwavering resolve.
