Correct Answer: A

Rationale: In this context, 'lethargy' refers to a state of sluggishness or lack of energy. The passage mentions that people with seasonal affective disorder (SAD) struggle with lethargy and chronic fatigue, impairing their daily lives. Therefore, the correct definition of 'lethargy' in this context is 'sluggishness.' Choice B, 'Irritability,' is incorrect as lethargy refers more to a lack of energy than to being irritable. Choice C, 'Energy,' is the opposite of lethargy. Choice D, 'Starvation,' is unrelated to the definition of lethargy in this context.

Correct Answer: C

Correct Answer: A

Rationale: The correct answer is A. The passage mentions a previous study by the same team on the connection between exercise and energy, indicating that the lab had conducted such research before. Choice B is incorrect because the passage actually states that low-impact exercise can help reduce fatigue in patients with serious health conditions. Choice C is incorrect as the passage indicates that an increase in energy levels does correspond to a reduction in fatigue. Choice D is incorrect as the passage does not provide information on the exact number of participants in each group.

Correct Answer: A

Rationale: In this context, 'shifts' refers to changes or alterations in brain chemistry and electrophysiology. The word 'alterations' best captures the idea that significant changes are occurring in the brain. 'Stints' (choice B) refer to short periods of time or work, which is not the meaning intended here. 'Removals' (choice C) and 'transfers' (choice D) do not fit the context of the sentence and are not related to the changes happening in the brain as described in the extract.

Correct Answer: D

Rationale: In the context of the passage, 'track' refers to a 'paved, circular path' for running or walking. The last sentence of the passage encourages people to get off the couch and onto the track, indicating a physical path for exercise. Choice A, 'Keep a record of,' is incorrect as the context does not suggest any relation to recording information. Choice B, 'A new attitude,' is unrelated to the context of exercise and fatigue reduction. Choice C, 'Follow carefully,' does not fit the context of physical activity and energy levels discussed in the passage.

Correct Answer: D

Rationale: The correct answer is D: 'Incontinence.' The passage discusses the negative consequences of spanking in childhood, such as increased aggression, delinquent behavior, and future sexual problems like coercive sex. However, incontinence is not mentioned as a possible result of being spanked. Therefore, it is the correct choice. Choices A, B, and C are all supported by the passage, making them incorrect answers.

Correct Answer: B

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: C

Rationale: In this context, 'established' means 'founded' or set up for a long time. The word is used to indicate that phototherapy has been a recognized and in place form of medicine for over a century. 'Created' (choice A) is incorrect as it implies the initial invention of phototherapy, which is not the intended meaning here. 'Ascertained' (choice B) means to find out for certain, which does not match the context of how phototherapy has been practiced. 'Reputable' (choice D) means having a good reputation, which is not the same as being long-standing or founded.
