When evaluating the credibility of a source during research, which statement is true?

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: D

Rationale: The destruction of barrier islands and coastal wetlands has left the mainland exposed, leading to increased damage and expenses from hurricanes. This implies a direct reason for the increased cost of recent hurricane seasons. The other choices do not directly address the reason for the increased expenses. Choice A talks about the intensity of Hurricane Katrina but does not explain the overall trend of increased expenses. Choice B mentions buildings being destroyed, which is a consequence rather than a reason for increased expenses. Choice C discusses an active period in the Atlantic Basin but does not connect it to the increased costs of hurricane seasons.

Correct Answer: A

Rationale: The passage provides factual information and details about the loss of barrier islands due to erosion and its impact on coastal communities. It focuses on defining and describing the issue rather than analyzing causes and effects, making it best classified as a definition essay. Choice B, cause/effect essay, would require a deeper exploration into the causes and effects of the erosion. Choice C, comparison essay, would involve comparing different aspects or scenarios, which is not the focus here. Choice D, persuasive essay, aims to convince the reader of a particular viewpoint, which is not the purpose of this passage.

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: A

Rationale: Including multiple headlines at the start of an article allows for the quick conveyance of the most important information about a significant event. In the case of the article about the assassination of Abraham Lincoln, the headlines serve as brief summaries of key details, such as the event itself, the perpetrator, the status of the President, and related incidents like the attempted assassination of Secretary Seward. These headlines help readers grasp the main points efficiently without having to read through the entire article. The purpose is to summarize the key details and attract readers' attention to engage them in the content. Choice B is incorrect because the purpose is not to sensationalize the story but to inform. Choice C is incorrect as the intention is not to incite panic but to provide essential information. Choice D is incorrect because the headlines serve a meaningful purpose and are not included just to fill empty space on the page.
