Mismatched premises and conclusion. The stimulus highlights one option out of a group, while (A) compares two specific options (classical and popular music). Further, the stimulus concludes with a recommendation that is the easiest to achieve, while (A) concludes that people should go with the more difficult option (classical music).

Mismatched premises. (B) is a straightforward recommendation (paddling with a friend) to achieve a goal (overcoming a fear of water). This is missing the aspect of emphasizing one option out of a group, and it is also missing the idea of making a certain recommendation because it is the easiest option. From the information given, we don’t know if the recommendation in (B) is the easiest way to achieve the goal.

The stimulus operates by providing a recommendation of one thing to focus on (the work of Edith Wharton) out of a group (classical U.S. writers) that facilitates a broader goal (a superb introduction to U.S. literature) because that recommendation is the easiest way to achieve the goal.

Mismatched premises. (D) provides a necessary condition (understanding the physical demands of Taiko-drumming) of achieving a goal (appreciating Taiko-drumming). (D) is missing the aspect of emphasizing one potential solution out of a group, and it is also missing the idea of making a certain recommendation because it is the easiest option.

Mismatched premises and conclusion. The stimulus highlights one option out of a group, while (E) compares two specific options (train and automobile travel). Further, the stimulus concludes with a recommendation that is the easiest to achieve, while (E) recommends one of the two options (train travel) because it has more benefits than the other options.
