Correct Answer: B

Rationale: The statement that rested people have better impulse control supports the claim that napping during the workday can lead to employees being happier, healthier, and more productive. Improved impulse control can result in better decision-making, including choosing nutritious food over junk food, which contributes to overall well-being and productivity. Choices A, C, and D do not directly address the relationship between napping and improved well-being or productivity, making them less relevant to supporting the claim.

Correct Answer: D

Rationale: The main idea conveyed in the extract is that Shia encounters a terrifying situation in the CFO's office. The passage describes Shia hearing strange noises, feeling fear, and encountering alarming events like crashes and howls. This builds tension and indicates a dangerous situation unfolding. Choices A, B, and C are incorrect as they do not capture the central theme of Shia facing a frightening encounter in the CFO's office.

Correct Answer: B

Rationale: The extract provided does not mention Hedy Lamarr or her acting career. Therefore, we cannot draw any conclusions about her from this text. Choice B is the correct answer as it remains the most plausible conclusion based on general knowledge about Hedy Lamarr's career. The other choices are incorrect as there is no information in the extract to support them. Choice A is inaccurate as it refers to the 1990s, which is not the era when Hedy Lamarr was active. Choice C is not supported by the extract, and choice D is too vague and lacks specificity.

Correct Answer: C

Rationale: The author's tone in the passage is informal. The passage provides a narrative about Hedy Lamarr's life and inventions, offering insights into her challenges and achievements in a conversational manner. The use of phrases like 'To relieve this boredom' and 'Just think, we might not have any of those things' indicates a casual and engaging tone, suitable for storytelling. Choice A, 'Sarcastic,' is incorrect as there is no evident use of sarcasm or irony in the passage. Choice B, 'Formal,' is incorrect because the tone is not stiff or ceremonious; instead, it is relaxed and personal. Choice D, 'Scientific,' is also incorrect as the tone is not focused on presenting technical information or research findings but rather on sharing a personal story.

Correct Answer: A

Rationale: The correct answer is A: 'Witty.' The tone of the passage is light-hearted and humorous, characterized by amusing details like the eccentric birthday party with zebras, monster trucks, and a limited buffet of boiled asparagus and pickled carrots. The mention of Dr. Creekstone planning an even bigger party with more zebras adds to the whimsical and humorous tone. Choices B, C, and D are incorrect as there is no indication of disbelief, hostility, or anxiety in the passage; instead, it conveys a sense of fun and amusement.
