What is an effective strategy to check for sentence fragments?

Select the correct text in the passage. which two sentences in this excerpt from f. scott fitzgerald's "winter dreams" seem to foreshadow dexter’s future obsession with “possessing” judy jones? now, of course, the quality and the seasonability of these winter dreams varied, but the stuff of them remained. they persuaded dexter several years later to pass up a business course at the state university—his father, prospering now, would have paid his way—for the precarious advantage of attending an older and more famous university in the east, where he was bothered by his scanty funds. but do not get the impression, because his winter dreams happened to be concerned at first with musings on the rich, that there was anything merely snobbish in the boy. he wanted not association with glittering things and glittering people—he wanted the glittering things themselves. often he reached out for the best without knowing why he wanted it—and sometimes he ran up against the mysterious denials and prohibitions in which life indulges.
