Correct Answer: A

Rationale: An essay by a historian about the lasting effects of the war is an example of a secondary source as it provides analysis and interpretation of primary sources like official documents, photographs, and letters. It offers a perspective that is based on research and not directly involved in the events, making it a valuable resource for understanding the historical context of World War I. Choice B, photographs of military equipment, is a primary source as it provides direct visual evidence from the time period. Choice C, a recorded interview with a veteran, is also a primary source as it offers firsthand accounts from someone directly involved in the events. Choice D, letters written by soldiers, are primary sources that offer insights into the personal experiences of individuals during the war.

Correct Answer: B

Rationale: In the context provided, the word 'move' is used to indicate that the vehicles are 'marked to move quickly,' which implies that they are intended to be sold rapidly. Therefore, the correct meaning of 'move' in this context is 'sell.' Options A, C, and D do not accurately capture the intention of the word as it is used in the passage. While 'advance forward' (Option C) might seem plausible, the context of a sales event and the urgency to buy due to low prices indicate that 'sell' is the most fitting interpretation.

Correct Answer: C

Rationale: The author's main purpose in the passage is to explain the influence of idealism on American social and political discourse. The passage discusses how idealistic viewpoints shape the discourse in America, advocating for specific ideals and beliefs (A) rather than explaining the beliefs of an idealist (B) or examining the impact of snake behavior on the ecosystem (D).

Correct Answer: C

Rationale: The passage uses specific evidence to support its claims. It presents factual information about the impact of private tutoring on students' grades, including a comparison of GPAs between students who had different types of tutoring. This specific evidence strengthens the argument by providing concrete data and examples. Emotional evidence, appeal to authority, and rhetorical questioning are not used in this passage, as it primarily relies on data and analysis to make its case.

Correct Answer: B

Rationale: The final sentence of the passage mentioning that Julia set a course for home indicates that Julia is making a deliberate decision to head towards her residence. This implies that she is planning to go home, suggesting that option B is the most accurate interpretation. Options A, C, and D are incorrect as they do not align with the context provided. Option A is incorrect as there is no indication that Julia cannot go directly home. Option C is incorrect as there is no mention of Julia returning to work. Option D is incorrect as there is no evidence in the passage to suggest that Julia is worried about the fire at her office spreading to her home.
