Choice D is the best answer because it most effectively uses a quotation from “The Bet” to illustrate the claim that the banker was very upset about something. The quotation indicates that the banker shed tears, which suggests that he was likely unhappy about something, and that his emotions were so strong that they kept him from sleeping for hours. These details suggest that the banker was very upset.
Choice A is incorrect because this quotation mainly describes the banker cautiously unlocking a door; it doesn’t suggest that he was particularly upset about anything. Choice B is incorrect because this quotation doesn’t mention whether the banker was experiencing any particularly strong negative feelings; instead, the quotation focuses on the quietness of the setting. Choice C is incorrect because this quotation states that the banker was feeling “delighted,” not that he was upset.
