A vegetarian diet is said to lower all of the following EXCEPT ___________.

Correct Answer: A

Rationale: The passage suggests that a vegetarian diet can provide sufficient protein and lower body fat, heart disease risk, and cholesterol, but it does not suggest that it lowers the need for protein.

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: A

Rationale: Cancer is not mentioned as a risk associated with inadequate sleep in the passage.

Correct Answer: D

Rationale: Based on the provided extract, sleeping helps with fatigue, memory, and learning. The passage mentions how a nap can refresh the brain, improve the ability to learn and remember, and enhance memory. However, the extract does not mention anything about sleeping helping with appetite. Therefore, the correct answer is D. Choices A, B, and C are supported by the content of the passage, emphasizing the positive effects of sleep on fatigue, memory, and learning.

Correct Answer: D

Rationale: The main idea of the passage is that lack of adequate sleep is becoming a major national health problem.

Correct Answer: A

Rationale: The passage suggests that a vegetarian diet can provide sufficient protein and lower body fat, heart disease risk, and cholesterol, but it does not suggest that it lowers the need for protein.

Correct Answer: B

Rationale: The correct answer is B: 'Untreated jaundice may cause brain damage.' This statement is a fact supported by the passage. Neonatal jaundice, if left untreated, can lead to brain damage due to excess bilirubin levels in the blood. Choice A is not a fact but a general guideline for nurses. Choice C is an opinion as it describes phototherapy blankets as valuable without citing a specific fact. Choice D is not a fact but a recommendation, advising to avoid neonatal units lacking phototherapy.

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: 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.
