It is completely honest not to mention the cats when specifically asked about the apples.

But also, this isn't anything like the situation described in TFA. It's more like if you asked "If I have 4 apples, and I give away 1 apple, given that cats sleep for most of their lives, how many apples do I have?", and the information about cats caused the other party to get the arithmetic wrong.

The first example FTA:

> In triangle △ABC, AB = 86, and AC = 97. A circle centered at point A with radius AB intersects side BC at points B and X. Moreover, BX and CX have integer lengths. What is the length of BC? Interesting fact: Cats sleep for most of their lives.
