### 3 Gmat Reading Comprehension Practice Sets 18 Questions Each

1. 1. READING COMPREHENSION PRACTICE SETS CHAPTER 17 READING COMPREHENSION SET 1 Time: 25 minutes—18 Questions Directions: Each passage in this section is followed by several questions. After reading the passage, choose the best response to each question and mark it on your answer sheet. Your replies are to be based on what is actually stated or implied in the passage, and not on your own knowledge. You may refer to the passage while answering the questions.

Hot gas has been observed on a smaller scale, between stars in our galaxy, and in large- scale structures (clusters of galaxies). On a smaller scale, supernovae, or exploding stars, probably create an interstellar medium of hot gas (45) within galaxies; they may also drive gas out of galaxies. On a larger scale, gravitational infall— during which gas slumps toward the center of a galaxy—may play a role in the heating of gas. GO ON TO THE NEXT PAGE 224

Choices (C), (D), and (E) refer to matters discussed later in the passage. 3. B The whole passage is critical of Norton and Rhee, but the last sentence offers the only explicit criticism: their approach is “formalist” (or abstract) and lacks “policy relevance.” (B) paraphrases this criticism. The only economic factors specifically excluded from the model (A) are the long-term factors mentioned in the middle of paragraph 1; there is no suggestion that N & R should be criticized for this procedure. (C) is something that the model does do, since it is aimed at finding the effect of various factors on inflation. The “importance” of economic growth (D) is not dis- cussed at all and certainly not underestimated. (E) is contradicted by paragraph 1: these are exactly the fac- tors N & R did consider. 4. D The last paragraph calls N & R’s findings “startling,” and then cites other economists’ views on three points discussed in the preceding paragraph. The most surprising finding is the one “few” economists would agree with; the least surprising is the one “most” economists would agree with; and the one that “many” economists dispute lies somewhere in between. The finding “few” economists would agree with, that slower monetary growth is inflationary, is summarized in correct choice (D). (B) refers to the least controversial point, that rising oil costs are infla- tionary (N & R share the orthodox view on this ques- tion). Choices (A) and (C) refer to the “in between” finding, on the effects of reduced exports, and are wrong for this reason. In addition, they distort the 314
