PP1 (Shorter) Verbal Section 2 (Easy) Q10
Pairing Up
First things first. We use the Pairing Strategy to identify any synonym pairs among the six answer choices.
Pair 1: inscrutable/uninformative (both mean we can't understand anything useful)
There's only one pair here, so we can eliminate the other answer choices: astonishing, disordered, harmless, and revealing.
The Right Answer
We can use Math Strategy to figure out the blank. There is a contrast happening with the "but"; on the right-hand side, the idea is that "dreams tell us much", so the left-hand side should convey the opposite idea. The Blank should be something like "doesn't tell us much".
The best (and only) match for this is the pair inscrutable/uninformative.
