Dietitian: It is true that nutrients are most effective when provided by natural foods rather than artificial supplements. While it is also true that fat in one’s diet is generally unhealthy, eating raw carrots (which are rich in beta carotene) by themselves is nonetheless not an effective means of obtaining vitamin A, since the body cannot transform beta carotene into vitamin A unless it is consumed with at least some fat.

Summarize Argument
Eating raw carrots alone isn’t an effective way to get vitamin A, even though natural foods are the best source of nutrients. The body needs a little fat to turn the beta carotene in carrots into vitamin A. While fat is generally unhealthy, a small amount is necessary to get vitamin A from carrots. This is because the body cannot get vitamin A from carrots unless the carrots are consumed with at least some fat.

Identify Argument Part
The stimulus text explains why people should be careful with how much fat they eat. The dietitian notes that while a little bit of fat is helpful because it helps your body get important vitamins from food, eating too much fat is bad.

A
It is mentioned as a reason for adopting a dietary practice that the dietitian provides a reason for not carrying to the extreme.
This describes the stimulus text’s role. The author recommends eating a little bit of fat with carrots so that the body can absorb vitamin A, but the stimulus text also cautions against eating too much fat because “fat in one’s diet is generally unhealthy.”
B
It is mentioned as the reason that is least often cited by those who recommend a dietary practice the dietitian disfavors.
The Dietitian doesn’t discuss any dietary recommendations she disfavors, so the stimulus text can’t support such a claim. Instead, the stimulus text qualifies the Dietitian’s recommendation. She suggests eating some fat, but not too much, because fat is “generally unhealthy.”
C
It is mentioned as a generally accepted hypothesis that the dietitian attempts to undermine completely.
The stimulus text doesn't present a hypothesis from others, and it isn't a claim the Dietitian tries to disprove. Instead, the Dietitian agrees with it as a clarification of her advice. She explains that while she recommends a little fat, she doesn’t recommend too much.
D
It is attacked as inadequate evidence for the claim that nutrients are most effective when provided by natural foods rather than artificial supplements.
The Dietitian doesn’t attack the stimulus text; she agrees with it and uses it to clarify her advice. She explains that while she recommends a little fat, she doesn’t recommend too much because fat is “generally unhealthy.”
E
It is cited as a bad reason for adopting a dietary habit that the dietitian recommends.
Rather than providing a bad reason for adopting a dietary habit (e.g., “It will make your mom mad!”), the stimulus text simply limits the Dietitican’s recommendation regarding the habit. The stimulus text explains why you should only include a little fat in your diet.
