Correct Answer: C

Rationale: 'Moult' refers to the act of shedding the outer shell, which is part of the insect's development. In the passage, it mentions insects that remain continually under water until they are ready to undergo their final moult and attain the winged state. This process of shedding the outer shell is crucial for insects transitioning from their aquatic larval stage to their aerial adult stage. Choices A, B, and D do not align with the specific context provided in the passage about the term 'moult.'

Correct Answer: B

Rationale: 'Haunt' in this context means to visit a place frequently or persistently, which aligns with Mr. Utterson's actions of regularly going to the door in the by street of shops. The other choices are incorrect because 'levitate' means to rise or float in the air, 'terrorize' means to cause extreme fear, and 'daunt' means to make someone feel intimidated or apprehensive, none of which accurately reflect the meaning of 'haunt' in this context.

Correct Answer: C

Rationale: The subtitle 'A Trivial Comedy for Serious People' in Oscar Wilde's play 'The Importance of Being Earnest' serves to reflect the trivial concerns of the characters and the superficiality of their lives. Wilde uses this subtitle to highlight the irony in portraying seemingly serious people who are preoccupied with trivial matters and appearances. Choice A is incorrect because the subtitle does not aim to emphasize the seriousness of the social critique but rather the triviality of the characters' lives. Choice B is incorrect as the subtitle doesn't downplay the seriousness of the play; instead, it juxtaposes the trivial with the serious. Choice D is incorrect because the subtitle does not aim to highlight the absurdity of taking serious matters lightly, but rather to underscore the triviality of the characters' concerns and behaviors.

Correct Answer: A

Rationale: The correct answer is A: 'The main sequence of events or the storyline.' The plot of a fiction story refers to the series of events that make up the storyline, including the rising action, climax, and resolution. It focuses on what happens in the story rather than the development of characters (choice B), the time and place setting (choice C), or events that are factually true (choice D), which are elements distinct from the plot.

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.'
