Critical Reading Question Section 4

  1. Which of the following, if true, would most effectively undermine the "simple definition" (line 72)? The answer is B, but I don't get how. I thought it was A btw it is in the 2nd edition blue book

btw It’s on pg.523

Since they couldn’t use “yawning” as the measure of “sleepiness,” they came up with an alternate method, i.e. to use how fast one falls asleep as the measure of sleepiness. This is based on the assumption written in the last sentence. However, if someone is very sleepy but cannot fall asleep because he/she is too sleepy (B) then one cannot correlate how fast someone falls asleep with the measure of sleepiness and contradics the assumption thus undermining the “simple definition.”

You have to find the answer that contradicts the assumption of the last sentence.
