Correct Answer: B

Rationale: In this context, 'haunt' means to constantly visit a place. Mr. Utterson is repeatedly going over the details of the situation in his mind, engaging with the problem persistently, as seen in the passage. The word does not imply levitation, terrorizing, or daunting in this context, making choices A, C, and D incorrect.

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: 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: C

Rationale: The central idea of the passage is to highlight the significance of understanding insects in ecosystems, not just focusing on their adaptability or life transitions. Choice A is incorrect as the passage does not introduce specific insects transitioning from water to air. Choice B is incorrect as the main focus is not solely on how insects adapt to their environment, but on their broader role in ecosystems. Choice D is incorrect as the passage does not discuss the duality of insect life, but rather their importance in the ecosystem.

Correct Answer: D

Rationale: The correct answer is D, Alliteration. Alliteration is used with the repeating 'l' sound in 'labyrinths of lamplighted city.' This phrase emphasizes the visual and auditory imagery through the repetition of the 'l' sound. Choices A, B, and C are incorrect. Hyperbole would be an exaggeration not present in the phrase, simile would involve a comparison using 'like' or 'as,' and a metaphor would imply a direct comparison without the use of 'like' or 'as,' which is not found in the given phrase.
