Correct Answer: A

Rationale: The correct answer is 'Plebeian.' In the given extract, the term 'working man' is associated with individuals who are part of the working class. Historically, plebeians were common working-class citizens. The passage emphasizes the dedication, patience, and support of the working man towards an enterprise, aligning with the characteristics attributed to plebeians in society. 'Viscount' is a noble title and not related to the working class. 'Entrepreneur' refers to a business person who takes risks to start a business, which is not the focus of the passage. 'Bourgeois' typically refers to the middle class, not specifically the working class like the term 'Plebeian.'

Correct Answer: A

Rationale: 'Enterprise' here refers to a company or organization, particularly one that requires effort and initiative. In the passage, the term 'enterprise' is used in the context of establishing a Mechanic's Institution, emphasizing the involvement and support of the working man in such an organization. Choice B, 'Courage,' is incorrect as the term refers more to determination and initiative in creating and supporting the institution rather than bravery. Choice C, 'Game,' and choice D, 'Cause,' are also incorrect as they do not align with the context provided in the passage.

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: C

Rationale: The correct answer is C, 'Third person omniscient.' The passage is written from a third person omniscient perspective, where the narrator knows the thoughts of multiple characters. This is evident as the narrator describes the thoughts and actions of various characters, such as the emperor, the treasurer, and the principal secretary. The narrator's knowledge extends beyond the main character, Gulliver, providing insights into the perspectives of others. Therefore, choices A, B, and D are incorrect. Choice A, 'First person,' would imply that the narrator is a character within the story, which is not the case here. Choice B, 'Third person limited,' would restrict the narrator's knowledge to only one character's thoughts and feelings, which is not the situation in this passage. Choice D, 'Objective,' would indicate a neutral and unbiased narration without delving into characters' thoughts, which is not the perspective used in this excerpt.

Correct Answer: C

Rationale: The sentence indicates that the insects undergo different stages of development, with the preparatory instars being aquatic and the adult instar being aerial. This highlights the adaptability of these insects to different environments. Choice A is incorrect as it focuses on the volume of water and air rather than the stages of development in different environments. Choice B is unrelated to the content of the sentence and does not capture the meaning accurately. Choice D is incorrect as it specifically mentions breathing through gills, which is not explicitly stated in the sentence. Therefore, choice C is the best interpretation of the sentence.
