Correct Answer: C

Rationale: The sentence is describing the life cycle of certain insects where their preparatory instars occur in the water, while the adult instar lives in the air. This means that the stage of preparation between molting or shedding of the exoskeleton happens in the water, but the final stage as adults is in the air. Choice A is incorrect as it misinterprets the meaning of the aquatic and aerial environments for the insect's life stages. Choice B is incorrect as it introduces a concept of the insect's abdomen being shaped like a star, which is not mentioned or relevant to the sentence. Choice D is incorrect as it introduces information about the insects' breathing organs, which is not directly related to the sentence's meaning about their life stages.

Correct Answer: C

Rationale: Alexander Graham Bell moved to Canada early in his life, before inventing the telephone and developing other technologies. Choice A is incorrect because Bell did not help found the National Geographic Society; this happened years after his major inventions. Choice B is incorrect because Bell developed a metal detector after inventing the telephone. Choice D is incorrect because Bell invented the telephone after moving to Canada.

Correct Answer: D

Rationale: Eczema is a topical condition, so Chapter 12 (section D) would be the most appropriate place to look for information on herbal remedies to combat it. Chapter 8 focuses on herbs for adult needs, and while it may contain some relevant information, it is not specific to topical conditions like eczema. Chapters 10 and 11 cover respiratory and digestive conditions respectively, which are not relevant to treating eczema. Therefore, Chapter 12 is the best choice for Clothilde to find herbal remedies to combat eczema.

Correct Answer: D

Rationale: The author should include information on the definition of lactose intolerance to help readers understand the need for lactose-free alternatives within the milk group. This clarification would provide context for why lactose-free options are recommended and help individuals make informed choices based on their dietary needs. Choices A, B, and C, although related to the topic of calcium-rich foods, do not directly address the issue of lactose intolerance and its implications for choosing suitable dairy alternatives.

Correct Answer: D

Rationale: The passage explicitly mentions that Malory included chapters on knights such as Lancelot and Gareth, and he discussed the relationships between Tristan and Isolde, and Lancelot and Guinevere. This shows that Malory did focus on a wider range of characters beyond just Arthur, Lancelot, and Guinevere. Therefore, the difference mentioned in option D is not accurate as it is identified in the passage that Malory did write stories about Gareth, Tristan, and Isolde. Choices A, B, and C are all correctly identified as differences between the two authors based on the passage provided.
