What does the following sentence most nearly mean? The preparatory instars of such insects are aquatic; the adult instar is aerial.

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: A

Rationale: The correct answer is A, 'skull.' The skull is part of the axial skeleton, not the appendicular skeleton. The axial skeleton, which includes the skull, vertebrae, and ribs, is located down the center of the body and protects vital organs such as the brain and heart. On the other hand, the appendicular skeleton consists of bones of the arms, legs, and the bones that attach these limbs to the axial skeleton. Choices B, C, and D (clavicle, scapula, pelvic bone) are part of the appendicular skeleton as they form the bones of the limbs and girdles that connect the limbs to the axial skeleton.

Correct Answer: B

Rationale: The correct answer is B. The passage mentions that after the death of Princess Charlotte Augusta, the remaining princes considered marrying and starting families since her death left the succession undetermined. Choice A is incorrect because the passage does not provide information about Victoria's reign bringing balance or righting any wrongs during her uncles' reigns. Choice C is incorrect as there is no mention of the Duke of Kent having a preference for a male heir or being disappointed with a female heir. Choice D is incorrect as the passage does not give details about King William IV's suspicions towards the Duchess of Kent or her motivations.

Correct Answer: D

Rationale: The information provided in the passage about the skeleton's structure and divisions, along with specific details like the number of bones and their functions, is characteristic of content found in a biography or a reference work focusing on anatomy. Biographies often include detailed factual information about historical figures, their lives, and aspects related to them, such as physical characteristics. A scholarly paper would delve deeper into analysis and research, rather than presenting basic factual information. The content in the passage is purely informative and factual, ruling out the possibility of it being part of a mystery or fictional story, which require narrative and plot elements rather than straightforward facts.

Correct Answer: C

Rationale: The passage indicates that Charles I's beheading had less to do with religion than with other political problems that England was facing. The author specifically states, 'Charles's own political that religion was less involved in this situation than in other situations.' This information supports the logical conclusion that the reasons for Charles I's beheading were more related to political issues rather than religious factors. Choice A is incorrect as the passage does not mention Charles II never marrying or having children. Choice B is incorrect as the passage focuses on the concerns regarding the Catholic succession, not the relief of losing children. Choice D is incorrect as the passage mainly discusses James II's Catholic leaning and the events related to the Catholic succession, but does not provide specific information about King James I's religious beliefs.
