Which of the following is a primary source that would contain the most useful information for a research paper on the effects different family structures have on children?

Correct Answer: C

Rationale: A study that examines the mental health of children from various family structures would provide the most comprehensive and relevant information for a research paper on the effects different family structures have on children. This type of study would offer insights based on empirical data and analysis, making it a reliable primary source. Choices A, B, and D might provide valuable perspectives, but a research study specifically focusing on the mental health outcomes of children from different family structures would offer more in-depth and specific information for the research paper.

Correct Answer: D

Rationale: The final comment in the passage indicates that Mr. Utterson intends to keep searching for Mr. Hyde, showing his determination. The passage describes how Mr. Utterson is troubled by questions about Hyde, engaging not just his intellect but also his imagination. Despite the lack of information obtained from Lanyon, Mr. Utterson continues to ponder the problem late into the night, suggesting his commitment to uncovering the mystery. Choices A, B, and C are incorrect because there is no indication in the passage that the speaker is considering a name change, experiencing an identity crisis, or mistakenly looking for the wrong person. The passage focuses on Mr. Utterson's persistent search for Hyde, emphasizing his unwavering resolve.

Correct Answer: C

Rationale: Option C is subjective and personal, making it less suitable for a formal essay about Salvador Dal­. In formal writing, it is important to maintain objectivity and focus on factual information rather than personal opinions. Choices A, B, and D provide relevant information about Dal­, his artwork, and his collaborations, which are more appropriate for inclusion in a formal essay.

Correct Answer: C

Rationale: The correct answer is C. The author specifically mentions in the passage that individuals should unplug appliances and chargers when not in use to reduce energy consumption. Choices A, B, and D are incorrect because they do not directly address the action of being aware of water and energy consumption. Choice A discusses food waste, choice B focuses on sustainable products and locally grown food, and choice D talks about participation in general without focusing on energy or water consumption.

Correct Answer: A

Rationale: The correct answer is 'Plebeian' as it represents the common people, which aligns closely with the definition of a 'working man.' 'Viscount' refers to a nobleman ranking above a baron but below an earl. 'Entrepreneur' is a person who organizes and operates a business, typically taking financial risks in the hope of profit. 'Bourgeois' relates to the middle class, typically with reference to its perceived materialistic values or conventional attitudes.

Correct Answer: D

Rationale: In this context, 'consumption' refers to the use or depletion of resources like water and energy. It is not about using the greatest amount (choice A) or the least amount (choice C) but about being mindful of how much you use to avoid depletion. 'Illness of the lungs' (choice B) is completely unrelated to the context of resource conservation discussed in the passage.

Correct Answer: D

Rationale: In this context, 'cajole' means to persuade someone by using flattery or promises, which is best represented by 'coax.' 'Prevent' (choice A) means to stop something from happening, 'threaten' (choice B) means to communicate an intention to harm, and 'insist' (choice C) means to demand something forcefully, so these choices do not fit the context of persuading with flattery or promises.

Correct Answer: C

Rationale: The author implies that neglecting the recommended actions will lead to the continued degradation of the environment and depletion of resources. The passage emphasizes the importance of being proactive in conserving resources to combat global warming and the depletion of natural resources. Choice A is incorrect because the author doesn't specify a timeframe for running out of resources. Choice B is incorrect as the focus is on environmental impact rather than economic consequences. Choice D is incorrect as the passage does not specifically mention the impact on local farmers.

Correct Answer: A

Rationale: In the provided text, 'principal' is referring to the primary or chief individual. The principal secretary for private affairs is considered second only to the treasurer, indicating a position of high importance. The term 'acolyte' (Choice B) refers to a ceremonial assistant, which does not fit the context. 'An individual who provides nurturing' (Choice C) and 'One in a subordinate position' (Choice D) do not accurately describe the role of the 'principal' in the text.
