Which of the following would be a useful source of information to determine the validity of the argument presented in the passage?

Correct Answer: D

Rationale: The passage emphasizes the importance of studying a foreign language in high school for future success, including college acceptance rates and job market demand. To evaluate the argument's validity, it is crucial to examine the direct impact of studying a foreign language on college acceptance rates. Choice D is the correct answer because it directly addresses this aspect by comparing the correlation between high school students' study of a foreign language and subsequent college acceptance rates. This comparison would provide concrete evidence supporting or refuting the argument presented in the passage. Choices A, B, and C, though related to language education, do not directly assess the specific relationship between studying a foreign language in high school and college acceptance rates, making them less relevant for evaluating the argument's validity.

Correct Answer: B

Rationale: Clothilde should look for more information on how to prune her elderberry plant and utilize the elderflowers for tea and homemade wine in Chapter 4: Herbs in Food. This chapter typically covers information on using herbs in various culinary and beverage preparations, which aligns with Clothilde's goals. Choices A, C, and D are incorrect because Chapter 4, specifically focusing on herbs in food, is the most relevant chapter for Clothilde's inquiry on utilizing elderflowers for tea and wine.

Correct Answer: C

Rationale: The logical conclusion that can be derived from the announcement is that the library has added the fee to discourage patrons from spending too long on the computers. This conclusion is supported by the fact that the library is limiting computer usage to 30 minutes and implementing a fee for extended use. Choice A is incorrect because there is no indication in the announcement that the library plans to purchase more computers. Choice B is incorrect as there is no mention of budget cuts or using the fee to compensate for them in the announcement. Choice D is incorrect as there is no information in the announcement about the library covering its Internet service costs by passing on the fee to patrons.

Correct Answer: C

Rationale: The passage provides detailed instructions on how to take care of a little girl, indicating that the intended audience is someone other than the child's parents. A babysitter is the most likely recipient of these instructions, as they are typically hired to care for children when the parents are away. The specific guidance on feeding, naptime routine, and other care tasks align with what a babysitter would need to know to care for a child in place of the parents. Choices A, B, and D are incorrect because the passage does not address the child's parents directly. It focuses on providing guidance to someone temporarily responsible for the child's care, such as a babysitter.

Correct Answer: D

Rationale: Based on the extract provided, a volleyball game can involve an entire class participating. The passage mentions that with just one net and one ball, an entire class can play volleyball. While the number of participants in a volleyball game can vary, the specific reference to a whole class in the passage indicates that a significant number of people can take part. Therefore, the correct answer is 'an entire class.' Choice A, '14,' is incorrect because the passage explicitly mentions that an entire class can participate, which typically involves more than 14 individuals. Choice B, '15,' is incorrect as it does not account for the flexibility of the number of participants in a volleyball game as stated in the passage. Choice C, 'half of a class,' is incorrect as the passage clearly states that an entire class can participate, not just half.
