Logical reasoning PrepTest 135 · Section 4 · Question 10

The number of people who have done something doesn’t change the average amount per person of those who have done that thing.

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.

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.

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.

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!
