Correct Answer: D

Rationale: The correct answer is D, 'Alliteration.' The phrase 'labyrinths of lamplighted city' uses alliteration by repeating the 'l' sound, creating a rhythmic and vivid image of a city illuminated by lamps. Alliteration is the repetition of initial consonant sounds in neighboring words, and in this case, it enhances the description of the city in the reader's mind. Choices A, B, and C are incorrect because there is no exaggeration (hyperbole), comparison using 'like' or 'as' (simile), or direct comparison without using 'like' or 'as' (metaphor) present in the phrase.

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: B

Rationale: The correct answer is B. In Wilde's play, 'The Importance of Being Earnest,' the characters' practice of leading double lives serves to reveal their hypocrisy and superficiality. This aligns with the central theme of the play, which satirizes the absurdities and trivialities of the British aristocracy. By showcasing the characters' dual nature through their double lives, the play effectively critiques the shallow social roles they inhabit. Choice A is incorrect because the concept of leading double lives does not necessarily show the characters' true personalities but rather their deceptive and hypocritical behaviors. Choice C is incorrect as while leading double lives may deepen the complexity of the characters, the primary focus is on exposing their hypocrisy and shallowness. Choice D is also incorrect as the concept of double lives does add layers of deception, but the key message lies in revealing the characters' superficiality and hypocrisy.

Correct Answer: A

Rationale: According to the table, one Heather Gray T-shirt in size small was ordered in January. The other choices are incorrect as they do not align with the information provided in the table, which clearly states that only one T-shirt of that description was ordered.

Correct Answer: A

Rationale: The correct answer is A because the passage primarily discusses certain insects that spend time in water during their early stages and then transition to an aerial life when they reach adulthood. It highlights how these insects, such as Stoneflies, May-flies, and Dragon-flies, live in water initially and then in the air during their adult stage. This central idea is best captured by choice A. <br> Choice B is incorrect because while the passage mentions gills as a part of the respiratory system of aquatic insects, it does not delve into entomology as a field. Choice C is incorrect as it does not solely focus on defining insect respiration but rather on the transition of certain insects between aquatic and aerial environments. Choice D is incorrect as the passage does not explicitly invite readers to participate in insect preservation efforts; it mainly focuses on describing the life cycle of specific insects.
