The question that makes the least sense to me so far...

As a film studies student, I said to myself when I saw the stimulus: "If you can't get this right, drop out."

@priscillasoliz I got it wrong for knowing what epoch means since I thought C only talked about different cultures but not different epochs

I'm a bit confused by the context can make some excludes all... If we think reading is a challenge therefore all can be excluded, for a class of 20, we should also reasonably exclude those numbers that are close enough to all like 18 or 19, but I don't think we should do that since we are not drawing the line.
