Mismatches premises and conclusion. (A) discusses how a change within one person (becoming famous) impacts a standard (quality of work), while the stimulus focuses on how two different options (large and small cars) each impact a standard (safety).

The conclusion of the stimulus advises the choice of one thing over another, while the conclusion of (A) claims that a seemingly positive change (becoming famous) can have a negative impact (diminishing an artist’s reputation).

Mismatched premises and conclusion. (B) focuses on the net effect of one action (indoor reading), identifying both negative effects (unhappiness) and positive effects (lifetime learning). The stimulus compares two options (large vs. small cars) based on one standard (safety).

The conclusion of the stimulus recommends one choice over another; (B) concludes that one should take an action (indoor reading) because the positive impacts outweigh the negative impacts.

Mismatched premises. While (C) does compare two different options (lightweight vs. heavy materials) for a certain goal (practicality), (C) is missing the aspect of the preferable option lowering the risk of a bad situation arising. In (C), the rationale for choosing lighter materials is because they’re cheaper to replace, not because they make bad situations less likely.

Mismatched premises and conclusion. (D) introduces a harmful behavior (sugar and fat in diet) and says that eliminating it completely has a negative impact (binges). The stimulus compares two options (large and small cars) based on one standard (safety).

(D) concludes that it is better to engage in a behavior in moderation than it would be to eliminate it completely. This is different from the conclusion of the stimulus, which recommends one choice over another

The argument weighs the net effects of two different options (exercising vigorously daily vs. average amount) for achieving a certain goal (health). While one of the options fares worse in a bad situation (daily exercise means less body fat to draw upon if you have a wasting illness), the argument concludes that this option is still preferable because it decreases the likelihood of the bad situation occurring (daily exercise reduces the chances of a wasting illness).
