GMAT Verbal Reasoning Practice Test 1

Because she has never had the jitters before, it is important for Brianais to try to do something to stop them. Therefore, this is not a criticism of her plan of action. The other options, however, all point out reasons why her plan of action may not be effective. If the jitters are caused by lack of sleep (choice A) or anxiety (choice E), then her plan will fail. Similarly, if her jitters worsen by a total withdrawal from caffeine (choice B), her plan will also fail. The fact that Brianais often gets the jitters when she drinks too much coffee (choice D) suggests that Brianais does not need to stop drinking coffee altogether; she just needs to cut back to her regular amount.
