How does the author distinguish between different groups of insects mentioned in the passage?

Correct Answer: B

Rationale: The author distinguishes between different groups of insects based on their habitat, categorizing them into aquatic and aerial categories. The passage mentions how some insects spend time under water while others live in the air, emphasizing the distinction between aquatic and aerial habitats. Therefore, choice B is correct. Choices A, C, and D are incorrect because the passage does not focus on describing the specific characteristics, adaptations, stages of development, or environments of the insects, but rather on their habitat and lifestyle.

Correct Answer: A

Rationale: The spiracles in insects serve the crucial function of allowing them to breathe atmospheric air even when submerged. The passage explains that insects have a system of branching air-tubes that carry atmospheric air with oxygen to all tissues. The air enters these tubes through paired air-holes or spiracles, enabling insects to respire even when they are underwater. Choices B, C, and D are incorrect because the spiracles do not protect internal organs from water pressure, filter oxygen from water for underwater breathing, or expel carbon dioxide from the body. The primary role of spiracles is to facilitate respiration by allowing insects to access atmospheric air.

Correct Answer: D

Rationale: The correct answer is D because the life cycle of insects is divided between water and air to demonstrate the evolutionary advantages of this adaptation. Insects have evolved to inhabit both aquatic and aerial environments, allowing them to thrive in diverse conditions. Choice A is incorrect because the division between water and air in the life cycle does not solely highlight adaptability but also evolutionary strategies. Choice B is incorrect because the question focuses on the reason for the specific division in the life cycle, not on environmental challenges. Choice C is incorrect because while metamorphosis is part of the life cycle, it does not directly explain why it is divided between water and air.

Correct Answer: A

Rationale: The correct answer is A: 'The absurdity of the British aristocracy and its social conventions.' The central theme of Wilde's play, as revealed through satire, is the critique of the absurdities and trivialities of the British aristocracy. Wilde uses clever dialogue, puns, and irony to expose the superficiality and hypocrisy of the upper classes. While sincerity and honesty in personal relationships are explored in the play, they are not the central theme. Choice C, the dual nature of social standing and resulting conflicts, is a partial theme but not the central one. Choice D, the challenges of maintaining personal integrity in a hypocritical society, touches on a theme present in the play, but it is not as central as the critique of the British aristocracy's absurdities and social conventions.

Correct Answer: A

Rationale: 'Bunburying' is significant in the play because it emphasizes the characters' desire to lead double lives and avoid the strict societal expectations placed upon them. The term highlights their need to escape the confines of social obligations through deception and subterfuge. By maintaining a fictional persona like Bunbury, the characters can freely navigate between different social spheres, allowing them to explore personal freedom and evade the constraints of their social status. This escapade showcases their yearning for independence and autonomy, contrasting with the societal norms they are expected to conform to. Choices B, C, and D are incorrect because 'Bunburying' in the context of the play is more about evading social duties through a dual identity, rather than reflecting indifference, willingness to deceive, or struggling to meet societal expectations.
