Does anyone else feel that the LSAT writers are very liberal w/ the word "prefer"

bripin18

just ran into an answer that entailed a baby preferring certain colors with no indication in the passage that it has any preference.

Can it really? How do we know?

Another example i've found is that one must PREFER an easier/more efficient task over a more difficult one! But why always??

In a broader sense, i've encountered a few situations in which the word "preferred" appears in answer choices, and i cant help but feel that the use of "preferred" is a sneaky attempt to get me to make an over-assumption!

Maybe it's just me, but anyways, I need to stop psyching myself out.
