PrepTest 140

Incorrect. The stimulus only discusses people overestimating a standard serving—the amount of the food that makes up one serving. It doesn't talk about their knowledge of recommended daily intake of the vitamins.

Correct. Argument or Facts:
Facts

Question Type:
Must Be True

Stimulus Summary:
Vitamins A and D are dangerous at high levels. Many foods have 100% recommended daily intake of them. Many people eat more than the standard servings of these foods.

Answer Anticipation:
Sounds like there are some people out there who are eating significantly more than the recommended daily intake of these vitamins, which is dangerous. Let's find an answer suggesting that.

Answer Explanation:
Since many people are consuming "two to three times" a standard serving of these foods, and standard servings have 100% the recommended daily intake of vitamins A and D, many people are therefore eating 2-3 times that recommended daily intake. This answer is supported by the stimulus.

Key Takeaway:
Digging back into answer choice (D), there are some words that are red flags in Must Be True questions. Very strong language—"always," "never," "essential," "independent," "unique," etc . . . —is suspect, and similarly strong language needs to be used in the stimulus to support it. Additionally, "should" is a red flag, especially when similar language ("should," "ought") isn't in the stimulus. Without that language, the LSAT generally won't consider a strong recommendation like that supported unless it states there are benefits without downsides.

Incorrect. There's no discussion of what people view as healthy, just what people view as a serving of certain foods.

Incorrect. The argument only discusses vitamins A and D—there could be other vitamins that people who eat these foods aren't getting in sufficient quantities. It's very hard to support a "should" answer without similar language in the stimulus.

Incorrect. The beliefs of the manufacturers are never brought up in the stimulus, so this answer is out of scope.
