Correct Answer: A

Rationale: First-hand accounts, like the speech by Charles Dickens, are considered primary sources as they provide direct evidence or original data from the event or time period. Primary sources offer firsthand information, such as diaries, speeches, letters, autobiographies, or original research reports. Secondary sources interpret and analyze primary sources, making them one step removed from the original event or period. Direct and indirect sources are not commonly used terms in the context of primary and secondary sources.

Correct Answer: A

Rationale: The first paragraph introduces the general characteristics of insects and their ability to live both on land and in the air, setting the stage for discussing specific examples in the second paragraph. The second paragraph then delves into examples of insects that transition from living underwater to the aerial phase, establishing a cause-and-effect relationship between the general concept introduced in the first paragraph and the specific examples in the second paragraph. Choice A is correct because the first paragraph gives the cause (insects being creatures of land and air) and the second paragraph provides the effect (specific examples of insects transitioning between water and air). Choices B, C, and D are incorrect because they do not accurately describe the relationship between the two paragraphs as cause and effect.

Correct Answer: A

Rationale: In this context, the word 'principal' refers to the primary or chief role that Reldresal holds as the principal secretary for private affairs. This term signifies his significant position and authority within the hierarchy. The other choices are incorrect because 'principal' does not mean 'an acolyte' (a follower or assistant), 'an individual who provides nurturing,' or 'one in a subordinate position.'

Correct Answer: C

Rationale: According to the extract, the term 'working man' refers to individuals who are actively employed and earn wages in a traditional sense. Charles Dickens emphasizes the importance of the working man having a share in the management of institutions designed for their benefit. This aligns with choice C, making it the correct answer. Choice A is incorrect as the extract does not mention anything about being well versed in the workings of the soul. Choice B is incorrect because the extract does not suggest that working men are not involved in social activities due to the physical demands of their work. Choice D is also incorrect as the extract does not focus on the historical transitions of the working man.

Correct Answer: C

Rationale: In Wilde's critique of the aristocracy, humor serves the purpose of critiquing without alienating the audience. By infusing humor into his work, Wilde can effectively highlight the flaws and absurdities of the upper classes while keeping the audience engaged and receptive. Option A is incorrect because the humor does not aim to soften the critique but rather to enhance its impact. Option B is incorrect as the humor in Wilde's work is not meant to make the critique more pointed and direct but rather more approachable. Option D is incorrect because while entertaining the audience, the primary function of humor in Wilde's critique is to provide a platform for social commentary without losing the audience's interest.
