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: B

Rationale: The main idea of the passage is that the FDA has a specialized program for regulating dietary supplements. The passage explains how the FDA regulates dietary supplements differently from drugs, focusing on the requirements for marketing, good manufacturing practices, monitoring safety, and taking action against unsafe products. Choice A is incorrect because while it mentions good manufacturing practices, it's not the central idea of the passage. Choice C is incorrect as there is no emphasis on prosecuting individuals in the passage. Choice D is incorrect because stating that the FDA is part of the federal government is not the main idea discussed in the passage.

Correct Answer: B

Rationale: The librarian's best course of action in this situation is to direct the student to the biography section of the library because the assignment specifically requires the student to read a biography. By helping the student select a biography at his reading level, the librarian ensures that the student is staying on task and fulfilling the assignment requirements. This approach also encourages the student to engage with physical books rather than relying solely on the Internet for research. Choice A is incorrect because it deviates from the assignment's requirement of reading a biography. Choice C is not the best option as it overlooks the specificity of the assignment and may lead the student away from the required task. Choice D is not ideal as it involves a lengthy process of inter-library loan which may not be necessary if suitable biographies are available in the library.
