Correct Answer: C

Rationale: The correct answer is C: Nikolai Rimsky-Korsakov. The passage highlights Rimsky-Korsakov's significant influence by mentioning that composers such as Alexander Glazunov, Sergei Prokofiev, and Igor Stravinsky studied under him. This demonstrates that Rimsky-Korsakov had a lasting impact on the development of these renowned composers. Choice A, Alexander Glazunov, is incorrect because the passage states that Glazunov studied under Rimsky-Korsakov, indicating he was influenced by him rather than being the most influential among The Five. Choice B, Modest Mussorgsky, is incorrect as the passage mainly focuses on his works and contributions but does not mention his influence on other composers. Choice D, Cesar Cui, is incorrect as he is considered one of the founders of the movement but is not highlighted for influencing other significant composers as Rimsky-Korsakov is. Therefore, based on the information provided, the author would likely agree that Nikolai Rimsky-Korsakov was the most influential among The Five.

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.

Correct Answer: B

Rationale: The correct answer is B. The passage extensively details the destructive nature of smoking tobacco products, highlighting the numerous harmful chemicals, addictive properties of nicotine, increased risk of various cancers, serious health conditions, and premature deaths associated with smoking. It also mentions the high costs due to government taxation on tobacco products, alongside the negative social aspects like the smell and staining effects. Choice A is incorrect as the passage emphasizes the severe dangers rather than comparing the healthiness of tobacco to other alternatives. Choice C is incorrect as it focuses solely on the financial aspect of tobacco taxation, omitting the broader health and social consequences discussed in the passage. Choice D is partially correct but not as comprehensive as choice B, which encapsulates the deadly, expensive, and socially unappealing nature of tobacco use as portrayed in the passage.

Correct Answer: B

Rationale: Answer choice B is the correct summary of the instructor's motive in sending the email to the students. The passage mentions that the instructor acknowledged the low exam scores, including a high failure rate and the need to reconsider the grading plan for the semester. This indicates that the instructor wants to adjust the grading plan to provide students with an opportunity to improve their scores. Choice A is incorrect as it focuses on expressing concern rather than on adjusting the grading plan. Choice C is unrelated as it discusses the purpose of a group project. Choice D is also incorrect as it mentions the strict grading policy set at the beginning of the semester, which is not the main focus of the email sent by the instructor.

Correct Answer: D

Rationale: The correct answer is D. Frost's poem emphasizes that opting for less conventional paths in life adds depth and meaning. Choices A, B, and C are incorrect because the poem specifically focuses on the importance of selecting uncommon routes rather than love, loss, general life decisions, or life's journey.
