Correct Answer: B

Rationale: The main idea of the passage is that studying a foreign language should be a compulsory requirement for high school graduation. This is emphasized due to its increasing importance for the global economy, college acceptance rates, and job market competitiveness. The passage argues for states to amend their requirements to reflect this necessity, highlighting the benefits of studying a foreign language. Choice A is incorrect because while the passage mentions job market competitiveness, the main focus is on the requirement for high school graduation. Choice C is incorrect as while understanding other cultures is a benefit of studying a foreign language, it is not the primary message of the passage. Choice D is incorrect as the passage does not solely focus on the necessity of studying a foreign language for college acceptance; rather, it advocates for its inclusion as a high school graduation requirement.

Correct Answer: D

Rationale: The focus of the passage is on Malory and Tennyson and their interpretations of the Arthurian legends. The mention of Charles Dickens in choice D is irrelevant and distracts the reader from the main discussion. While the other choices discuss Malory's prose style, his focus on moral elements, and Tennyson's approach to the Arthurian stories, choice D brings in a comparison to Charles Dickens and his novels about lower-class children in Victorian England. This mention of Dickens does not directly relate to the main theme of the passage, making it the correct answer as the distracting sentence.

Correct Answer: B

Rationale: The correct answer is B: '200.' According to the Dewey Decimal System, religion falls under section 200. Traditional Judaism research aligns with religious studies, making section 200 the most suitable for finding relevant information. Choices A, C, and D do not directly relate to religious topics and are therefore less likely to contain information on traditional Judaism.

Correct Answer: B

Rationale: The correct answer is B, Cobra. In the food chain diagram, cobras are often considered apex predators, meaning they are at the top of the food chain and do not have natural predators. Vultures (choice A), although scavengers, may face competition but not direct predators. Mongooses (choice C) are known for preying on snakes, including cobras, and aardvarks (choice D) are part of the food chain and have predators like lions and hyenas.

Correct Answer: B

Rationale: Answer choice B best summarizes the main point of the passage by highlighting the significant influence of The Five, a group of Russian musicians who diverged from traditional classical training, on classical music in Russia and beyond. The passage emphasizes how despite their unconventional methods and lack of formal training, The Five had a lasting impact that extended far beyond their era. It showcases the group's influence on classical music history, making choice B the most appropriate summary. Choices A, C, and D do not capture the central theme of the passage, which revolves around The Five's unique approach and lasting impact, unlike choice B.
