   Most fad diets require that everyone following them eat plenty of

   While we have reason to think it would make good sense for most fad diets to require fruits and veggies, we have no evidence that this is what they currently are recommending.

   Fruits and vegetables are the only foods that contain enough different nutrients to protect against a wide

   Too Strong: the only Only One Mentioned ≠ Only One Just because "fruits and veggies" are the only type of food mentioned that protects against a wide range of health problems doesn't mean we're allowed to infer that "fruits and veggies" are the only type of food.

   Any two people have different health problems and thus different

   This is enticing people into a mis-read of "dietary needs vary widely from person to person", which does not mean that every person has a unique set of dietary needs, it just means that there's a high variance within the test. If I proctored a practice LSAT for 100 students and said "the scores varied widely from person to person", that wouldn't mean that "any two people had different LSAT scores".

   Why this is right

   This is derivable from the first two claims. It's a "Reconcile the Pivot" sort of inference, synthesizing the ideas of Most fad diets = narrow range of nutrients People = vary widely in nutrients needed If we said "most fad LSAT programs cater to a very narrow part of the test" and "people vary widely in terms of what part of the test they need help with most", then we could infer that "most fad LSAT programs fail to satisfy the needs some LSAT students". Remember, "some" just means "at least one", so contradicting this claim would mean we think it's possible that "most fad diets successfully satisfy the needs of 100% of people".

   Too Strong: very few, if any3% picked this

   There are very few if any nutrients that are contained in every food other than

   This is making a strong, out of scope statement. It's saying there are very few nutrients that would be contained in every non-fruit / non-veggie food. I think they're trying to entice people into thinking, "if dietary needs vary widely from person to person, then there must not be many common denominator ingredients." We just don't know. If we supposed there were 100 nutrients out there, and all non-fruit, non-veggie foods have nutrients 1 thru 20, that would invalidate this answer but it would still allow the paragraph to be true. Foods could vary a lot in terms of which of the remaining 80 nutrients they have or don't have, and people could vary a lot in terms of which of those remaining 80 nutrients they need or don't need. In other words, it's possible for there to be many common denominator nutrients, while there is still a lot variety to other nutrients, and perhaps people are relatively similar when it comes to these common denominator nutrients but are more widely divergent when it comes to these more intermittent nutrients.
