Correct Answer: D

Rationale: The kind of sources different audiences value can indeed influence the credibility of a source for them. Different audiences may place varying levels of trust in different types of sources, such as peer-reviewed journals, government reports, or mainstream media outlets. Understanding the preferences of the target audience is essential for establishing credibility when presenting information. Choices A, B, and C are incorrect. The author's reputation is important but not more critical than citing sources, as proper citations contribute to transparency and reliability. The recency of a source is essential but not always the most crucial factor; relevance to the subject matter is also significant. The author's point of view and purpose are indeed relevant to assessing credibility; understanding their biases and intentions is vital in evaluating the reliability of a source.

Correct Answer: C

Rationale: In the context of the article describing the assassination of President Lincoln, the word 'mortal' is used to describe a wound that will cause death. The sentence 'The wound is mortal' indicates that the wound is fatal and will result in the President's death. Therefore, the correct synonym for 'mortal' in this context is 'fatal,' meaning causing death. Choice A, 'deadly,' is the best synonym as it directly relates to causing death. Choices B and D, 'recoverable' and 'dangerous,' do not accurately reflect the meaning of 'mortal' in this context.

Correct Answer: C

Rationale: Choice C correctly matches the samples with incompletely met criteria. It states that sample 1's evidence is not relevant, sample 2's evidence is not factual, and sample 3's evidence is not sufficient. This aligns with the criteria mentioned, indicating a lack of relevance, factual accuracy, and sufficiency in each sample, respectively. Choices A, B, and D do not accurately match the samples with the given criteria, making them incorrect. In choice A, while sample 1's evidence is not sufficient, sample 2's evidence is not relevant, and sample 3's evidence is not factual, the order in which these aspects are mentioned is not aligned with the criteria provided. Choice B has the correct order but mismatches the criteria with the samples. Choice D incorrectly assesses the evidence of the samples, focusing on sufficiency and relevance but not aligning with the specified criteria for each sample.

Correct Answer: C

Rationale: The university determined the lunch schedule by considering when the most faculty members from each department usually enter the canteen. This information is provided in the announcement where it states that the schedules were recommended based on when members of each department should visit the canteen for lunch. Choice A is incorrect because the schedule was not arranged solely based on the department with the most faculty members. Choice B is incorrect as it implies checking with departments about the majority of faculty members entering the canteen, which is not explicitly mentioned. Choice D is incorrect as it simplifies the university's decision-making process, which involved considering the timing of faculty members from different departments entering the canteen.

Correct Answer: A

Rationale: The correct answer is A. The passage mentions that explorers like Lewis and Clark were sent to the newly acquired Louisiana Territory immediately after the Louisiana Purchase. This indicates that explorers were already on their way to the region following the purchase. Choice B is incorrect as there is no direct mention of the government wanting to increase its power right after the purchase. Choice C is incorrect as the passage does not state that government officials would specifically ensure explorers were dispatched to the region. Choice D is incorrect because there is no information provided in the passage about explorers expecting payment for their work.
