This passage is presented in first-person perspective from the point-of-view of a narrator who uses the pronoun "I." The narrator's particular voice and perspective is conveyed throughout the passage, but most strongly in the second paragraph, where he follows a tangent about the use of the phrase "dead as a door-nail" at the end of the first paragraph.

Mind! I don’t mean to say that I know, of my own knowledge, what there is particularly dead about a door-nail. I might have been inclined, myself, to regard a coffin-nail as the deadest piece of ironmongery in the trade. But the wisdom of our ancestors is in the simile, and my unhallowed hands shall not disturb it, or the country’s done for. You will therefore permit me to repeat, emphatically, that Marley was as dead as a door-nail.

This tangent emphasizes the narrator's authorial perspective, in that he is discussing the reasons behind his use of the phrase "dead as a door-nail" and not some other phrase, despite his thoughts on the phrase. ("I might have been inclined, myself, to regard a coffin-nail as the deadest piece of ironmongery in the trade"). Because the second paragraph focuses on the narrator's perspective and reasoning behind his use of a certain phrase, the correct answer is that it is the second paragraph in which the narrator's particular voice and perspective are most apparent.

The author has chosen with case the order in which he presents various descriptors in the indicated sentence:

Scrooge and he were partners for I don’t know how many years. Scrooge was his sole executor, his sole administrator, his sole assign, his sole residuary legatee, his sole friend, and sole mourner. And even Scrooge was not so dreadfully cut up by the sad event, but that he was an excellent man of business on the very day of the funeral, and solemnized it with an undoubted bargain.

To make this question more complex, three of its answer choices are true statements about the effect of the author's choice and sequence of words, and it's your job to pick out the one answer choice that is not correct. Let's consider each of them:

"The sequence of the underlined sentence, at the end of the sentence, redirects the reader's attention to Marley's death." - This is true. The author concludes the repetition of "his sole _____" noun phrases with "sole mourner," which redirects the reader to consider Marley's death. This acts as a transition into the next sentence, which describes how Scrooge reacted to Marley's death. This statement is true, so this answer choice isn't the correct one.

"The author's word choice suggests that Scrooge and Marley were involved in business, legal, and/or financial pursuits together." - This statement is also true. The author uses terms like "executor," "administrator," "assign," and "residuary legatee." This very specific language conveys to the reader that Scrooge and Marley were involved in business, legal, and/or financial pursuits together.

"The repetition emphasizes the fact that Scrooge was one of the only people, if not the only person Marley was moderately close to." - This is another accurate statement. Scrooge's roles in relation to Marley span from legal and business jargon terms to his only friend as well as his only mourner. The author's choice to present this information in the form of a repeating list emphasized the word "sole," and conveys that Scrooge was one of the only people if not the only person Marley was moderately close to.

"The order in which the sentence presents its options suggests that Scrooge valued his role as Marley's sole assign more than his status as Marley's sole residuary legatee." - This answer choice is not accurate, so it is the correct answer. The sentence states that Scrooge was Marley's "sole mourner" at the end, whereas it states his business associations first. Scrooge's status as Marley's "sole mourner" is emphasized because it appears at the end of the sentence, and Scrooge's status as Marley's friend is emphasized because it does not employ jargon like the four preceding phrases do; however, nothing about the sentence order suggests that Scrooge values one of the roles related with jargon above any of the other roles related with jargon.
