GRE Sample Test 4 Verbal Reasoning 1

Without structural road signs, you need to see if paraphrasing or key words can help you find synonyms. Scientists have observed odd fish behavior that precedes seismic events—the fish jump out of the water. Your paraphrase and prediction might look something like this: “Scientists ‘theorize’ that fish respond to physical precursors of seismic events.” Both choices (D) and (F), hypothesize and contend, fit this definition, and are therefore the correct answers. Choice (A) repudiate means to reject an idea, not present one. Scientists don’t authorize information, so choice (B) is also incorrect. Choice (C) foresee does imply prediction, but one based on intuition, not on observed behavior. Finally, it wouldn’t make sense for scientists to (E) question their own prediction in this context.
