Which of the following is true of hypotheses of the form 'All x are y'?

Correct Answer: D

Rationale: In hypotheses of the form 'All x are y,' the hypothesis is making a claim that all instances of x also fall under y. Therefore, if something is y but not x, it disproves the hypothesis because it contradicts the assertion that all x are y. Choice A is incorrect because something that is neither x nor y doesn't provide evidence against the hypothesis. Choice B is incorrect because if something is both x and y, it actually supports the hypothesis. Choice C is incorrect as something that is x but not y doesn't disprove the hypothesis, as it could still be consistent with the claim that all x are y.

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: Encountering an automobile with eighteen wheels contradicts the hypothesis that all automobiles have only four wheels. This contradicts the initial hypothesis, proving it to be false. The passage explains that when evidence disproves a hypothesis, it directly contradicts the hypothesis, leading to its disproof. In the context of the monkey example provided, encountering a hairless monkey out of many hairy monkeys disproved the hypothesis 'All monkeys are hairy.' Therefore, the presence of an automobile with eighteen wheels disproves the hypothesis that all automobiles have only four wheels. Other choices are incorrect because encountering such an automobile directly contradicts the initial hypothesis, leading to its disproof, rather than proving it, raising its probability, or decreasing its probability.

Correct Answer: D

Rationale: The guide words degressive and delectation are given, suggesting that the word on the next page would start with 'dei.' In alphabetical order, 'deity' comes after 'delectation' and 'degressive,' making it the most likely word to appear on the following page of the dictionary. Choices A, B, and C do not follow the alphabetical progression based on the guide words provided.

Correct Answer: D

Rationale: The writer uses description as a structural pattern to show readers something instead of telling them. By vividly describing Thomas Jefferson, his life, achievements, and significance, the reader can form a mental image and understanding of who he was without being explicitly told. Description allows for a more engaging and immersive experience for the reader compared to being told facts directly. Choice A, 'Division,' involves breaking down a subject into parts for analysis and understanding, not necessarily showing something instead of telling it. Choice B, 'Narration,' is the act of telling a story or recounting events, which involves direct communication rather than showing through vivid details. Choice C, 'Definition,' is providing the meaning of something, which is informative but does not create a visual or immersive experience like description does.

Correct Answer: C

Rationale: The correct answer is "C: conserve." In a dictionary page where the guide words are "considerable" and "conspicuous," the word "conserve" would be an entry as it falls alphabetically within those guide words. Choice A, "consonantal," starts with a different letter, so it would not be located between the guide words. Choice B, "consumption," also starts with a different letter and would not be between the guide words. Choice D, "conquistador," starts with a different letter and is also far from the guide words alphabetically, making it an incorrect entry on this particular page.

Correct Answer: C

Rationale: Based on the provided water schedule for addresses in the town of Audley, odd-numbered addresses ending in 7 and 3, like 5487 South Elm Street, are allowed to water their lawns on Thursdays. Therefore, the Morgan family will be able to water their lawn on Thursday. Choice A (Tuesday), Choice B (Wednesday), and Choice D (Saturday) are incorrect as they do not align with the watering schedule for odd-numbered addresses as per the town's guidelines.

Correct Answer: C

Rationale: The type of writing used in the passage is expository. Expository writing aims to provide information, explain concepts or ideas, and present factual details without trying to persuade or tell a story. In the passage, the text focuses on providing factual information about 'The Five,' their backgrounds, and their influence on classical music without any persuasive elements or narrative storytelling. The passage educates and informs the reader about the topic, which aligns with the characteristics of expository writing. Therefore, 'expository' is the correct description. Choice A (narrative) is incorrect as the passage does not tell a story but rather presents factual information. Choice B (persuasive) is incorrect because there is no attempt to persuade the reader in the passage. Choice D (technical) is also incorrect as the passage does not involve technical instructions or specialized technical details, but rather general information about the subject matter.

Correct Answer: A

Rationale: It can be inferred from the advertisement that a person staffing this position may work independently and/or as part of a team. The job description mentions the requirement for the ability to work both self-directed and as part of a team, indicating flexibility in working styles. Choice B is incorrect as Veronica Smith is mentioned as the contact for application submission, not the hiring decision-maker. Choice C is incorrect as there is no mention of caseload sizes for new hires. Choice D is incorrect as the advertisement does not specify part-time work as an option.
