Correct Answer: D

Rationale: The 900 section contains works on history, geography, and biography, which is where Jorgen is likely to find early maps by Eratosthenes. Eratosthenes was not only a mathematician but also a geographer, so his maps would be classified under history and geography, making Section 900 the most appropriate choice. Sections 100, 300, and 600 do not specifically cater to history, geography, or biography where Eratosthenes' early maps would be located.

Correct Answer: D

Rationale: The best advice for the student would be to locate texts in the library related to World War II in America and look for references to internment camps. This choice is the most appropriate as it focuses on accessing specific and credible sources directly related to the research topic. Choices A and C are too broad and may not provide in-depth information on the internment camps. Choice B, while related to American history, may not offer the specific details needed for the research assignment on Japanese-American internment camps during World War II.

Correct Answer: B

Rationale: Jorgen should go to section 400 in the library to learn more about the Greek alphabet and the meaning of the word 'beta'. Section 400 is dedicated to languages, which makes it the most appropriate place for this specific inquiry. Choices A, C, and D are incorrect because section 200 is dedicated to religion, section 700 covers arts and recreation, and section 900 focuses on history, geography, and biography, none of which would provide information about the Greek alphabet or the word 'beta'.

Correct Answer: C

Rationale: The central idea of the passage is to highlight the significance of understanding insects in ecosystems, not just focusing on their adaptability or life transitions. Choice A is incorrect as the passage does not introduce specific insects transitioning from water to air. Choice B is incorrect as the main focus is not solely on how insects adapt to their environment, but on their broader role in ecosystems. Choice D is incorrect as the passage does not discuss the duality of insect life, but rather their importance in the ecosystem.

Correct Answer: B

Rationale: The correct answer is B. Juggernaut is used to describe something that is powerful and overwhelming, instilling fear. In the passage, Mr. Utterson's mind is toiling and besieged by questions, engaging his imagination and leaving him restless in the darkness of the night. This conveys a sense of fear and being overwhelmed, aligning with the meaning of 'Juggernaut.' Choices A, C, and D are incorrect as they do not relate to the context provided in the passage. The passage does not mention any apparition appearing at daybreak, association with space travel, or Mr. Utterson finding it soothing.
