Stimulus Summary

Goal: Reduce the amount of fat in one’s diet.
Method: Cut red meat consumption in half.
Outcome: Substantial increase in fat.

Answer Anticipation

When someone cuts a substantial amount of calories out of their diet, they’ll need to replace it with something. In this case, they cut out red meat, but saw their total fat consumption increase, so whatever they replaced those calories with must have more fat in it than red meat.

Answer choices

  1. A
    Many more people have Remaining source text redacted.
    Why choice A is not credited
    The number of people who have done something doesn’t change the average amount per person of those who have done that thing.
  2. B
    Higher prices over the Remaining source text redacted.
    Why choice B is not credited
    Even if some did it to save money, we know that cutting red meat out of a diet is also done to cut fat. The reasons behind the change don’t explain where all that extra fat is coming from.
  3. C
    People who reduce their Remaining source text redacted.
    Why choice C is not credited
    This answer can sound tempting at first. However, if someone is eating a similar diet to someone else, but they cut red meat (and the fat associated with it) out of their diet, we wouldn’t expect to see their total fat go up! This answer doesn’t explain where the “substantially more” fat in their diet is coming from.
  4. D
    People who reduce their Remaining source text redacted.
    Why choice D matches the stem
    If people are replacing the red meat with food that is even higher in fat, then we would expect to see their total fat intake increase. This answer explains where the extra fat is coming from, so it’s the correct answer.
  5. E
    Studies have shown that Remaining source text redacted.
    Why choice E is not credited
    Without getting into how this would impact the statistics presented in the stimulus, this answer talks about there being “slightly less” fat in red meat to explain a diet with “substantially more fat” than diets without red meat. That disconnect is enough to eliminate this answer without getting into how this would change the numbers!
