【OG20-P458-603题】The passage implies which of the following about the five asteroids mentioned? (highlight)
Twelve years ago and again five years ago, there were extended periods when the Darfir Republic's currency, the pundra, was weak: its value was unusually low relative to the world's most stable currencies. Both times a weak pundra made Darfir's manufactured products a bargain on world markets, and Darfir's exports were up substantially. Now some politicians are saying that, in order to cause another similarly sized increase in exports, the government should allow the pundra to become weak again. Which of the following, if true, provides the government with the strongest grounds to doubt that the politicians' recommendation, if followed, will achieve its aim?
Editorial: In Ledland, unemployed adults receive government assistance. To reduce unemployment, the government proposes to supplement the income of those who accept jobs that pay less than government assistance, thus enabling employers to hire workers cheaply. However, the supplement will not raise any worker’s income above what government assistance would provide if he or she were not gainfully employed. Therefore, unemployed people will have no financial incentive to accept jobs that would entitle them to the supplement.Which of the following, if true about Ledland, most seriously weakens the argument of the editorial?
Vorland’s government is planning a nationwide ban on smoking in restaurants. The objection that the ban would reduce restaurants’ revenues is ill founded. Several towns in Vorland enacted restaurant smoking restrictions five years ago. Since then, the amount the government collects in restaurant meal taxes in those towns has increased 34 percent, on average, but only 26 percent elsewhere in Vorland. The amount collected in restaurant meal taxes closely reflects restaurants’ revenues. Which of the following, if true, most undermines the defense of the government’s plan?
Most of the world's supply of uranium currently comes from mines. It is possible to extract uranium from seawater, but the cost of doing so is greater than the price that uranium fetches on the world market. Therefore, until the cost of extracting uranium from seawater can somehow be reduced, this method of obtaining uranium is unlikely to be commercially viable. Which of the following would it be most useful to determine in evaluating the argument?
Given a positive number N, when N is rounded by a certain method (for convenience, call it Method Y), the result is if and only if n is an integer and .In a certain gas sample, there are, when rounded by Method Y, molecules of H2 and also molecules of O2. When rounded by Method Y. what is the combined number of H2 and O2 molecules in the gas sample?(1) The number of H2 molecules and the number of O2 molecules are each less than (2) The number of H2 molecules is more than twice the number of O2 molecules
Unlike other Mayan cities, Cancun's commercial power throughout the lowlands seems to be from using its strategic position at the foot of the highlands, which were a source of jade, obsidian, and other valuable commodities.

The hognose snake puts on an impressive bluff, hissing and rearing back, broadens the flesh behind its head the way a cobra does, feigning repeated strikes, but, having no dangerous fangs and no venom, eventually, if its pursuer is not cowed by the performance, will fall over and play dead.
