GRE Sample Test 2 Verbal Reasoning 2

The phrase “squandered his life’s savings on unprofitable business ventures” tells you that the entrepreneur had no money left. The blank needs a word that means broke. Former and unlikely are tempting choices, but they don’t match broke. Eliminate them.
Eccentric also doesn’t match, while perturbed only describes the entrepreneur’s possible feelings. Insolvent agrees with the clue, so keep it.
