iduals (E) data concerning the ages of fossil samples cannot provide reliable information about behavioral differences between extinct carnivores and presentday carnivores 8. According to the passage, if the researchers had NOT found that two extinct carnivore species were free of tooth breakage, the researchers would have concluded that (A) the difference in breakage frequencies could have been the result of damage to the fossil remains in the La Brea pits (B) the fossils in other Pleistocene sites could have higher breakage frequencies than do the fossils in the La Brea pits (0 Pleistocene carnivore species probably behaved very similarly to one another with respect to consumption of carcasses (D) all Pleistocene carnivore species differed behaviorally from presentday carnivore species (E) predator densities during the Pleistocene era were extremely high 12 (45) cannot be found again and bee as inaccessible as if they had never been discovered. Indeed, with the help of a puter, sold artifacts could be more accessible than are the pieces stored in bulging museum basements. Prior to sale, each could be (50) photographed and the list of the purchasers could be maintained on the puter. A purchaser could even be required to agree to return the piece if it should bee needed for scientific purposes. It would be unrealistic to suggest that illegal (55) digging would stop if artifacts were sold on the open market. But the demand for the clandestine product would be substantially reduced. Who would want an unmarked pot when another was available whose provenance was known, and that was dated (60) stratigraphically by the professional archaeologist who excavated it? The Official Guide for GMAT174。 Review 13th Edition Line Archaeology as a profession faces two major problems. First, it is the poorest of the poor. Only paltry sums are available for excavating and even less is available for publishing the results (5) and preserving the sites once excavated. Yet archaeologists deal with priceless objects every day. Second, there is the problem of illegal excavation, resulting in museumquality pieces being sold to the highest bidder. (10) I would like to make an outrageous suggestion that would at one stroke provide funds for archaeology and reduce the amount of illegal digging. I would propose that scientific archaeological expeditions and governmental (15) authorities sell excavated artifacts on the open market. Such sales would provide substantial funds for the excavation and preservation of archaeological sites and the publication of results. At the same time, they would break the illegal (20) excavator39。 s grip on the market, thereby decreasing the inducement to engage in illegal activities. You might object that professionals excavate to acquire knowledge, not money. Moreover, ancient artifacts are part of our global cultural heritage, (25) which should be available for all to appreciate, not sold to the highest bidder. I agree. Sell nothing that has unique artistic merit or scientific value. But, you might reply, everything that es out of the ground has scientific value. Here we part pany. (30) Theoretically, you may be correct in claiming that every artifact has potential scientific value. Practically, you are wrong. I refer to the thousands of pottery vessels and ancient lamps that are essentially duplicates of (35) one another. In one small excavation in Cyprus, archaeologists recently uncovered 2,000 virtually indistinguishable small jugs in a single courtyard. Even precious royal seal impressions known as I39。 melekh handles have been found in abundance (40) —more than 4,000 examples so far. The basements of museums are simply not large enough to store the artifacts that are likely to be discovered in the future. There is not enough money even to catalog the finds。 as a result, they 13 Reading Comprehension Sample Questions 8. The primary purpose of the passage is to propose (A) an alternative to museum display of artifacts (B) a way to curb illegal digging while benefiting the archaeological profession (C) a way to distinguish artifacts with scientific value from those that have no such value (D) the governmental regulation of archaeological sites (E) a new system for cataloging duplicate artifacts 9. The author implies that all of the following statements about duplicate artifacts are true EXCEPT (A) a market for such artifacts already exists (B) such artifacts seldom have scientific value (C) there is likely to be a continuing supply of such artifacts (D) museums are well supplied with examples of such artifacts (E) such artifacts frequently exceed in quality those already cataloged in museum collections 10. Which of the following is mentioned in the passage as a disadvantage of storing artifacts in museum basements? (A) Museum officials rarely allow scholars access to such artifacts. (B) Space that could be better used for display is taken up for storage. (C) Artifacts discovered in one excavation often bee separated from each other. (D) Such artifacts are often damaged by variations in temperature and humidity. (E) Such artifacts often remain uncataloged and thus cannot be located once they are put in storage. 14 Line lo and Europa, the innertwo of Jupiter39。 s four largest moons, are about the size of Earth39。 s moon and are posed mostly or entirely of rock and metal. Ganymede and Callisto are larger and roughly (5) half ice. Thus, these four moons are somewhat analogous to the plas of the solar system, in which the rock and metalrich inner plas ar。
