GWD-29-Q40

Mice that have been given morphine are very likely to develop blood poisoning because bacteria that normally reside in the intestine typically respond to morphine by migrating into the bloodstream. However, when mice are given both morphine and the new drug naltrexone, blood poisoning is much less frequent, although it does still occur. These results provide support for researchers’ prediction that naltrexone will turn out to be toxic to certain types of bacteria.

Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction?

A. After being administered to mice, naltrexone does not pass from the bloodstream into the intestine.
B. Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.
C. Mice that have been given naltrexone but not morphine have no greater risk of developing blood poisoning than do mice that have not been given either substance.
D. The increased risk of blood poisoning is not the only harmful effect on mice of being given morphine.
E. Conditions other than the presence of intestinal bacteria in the bloodstream can cause blood poisoning in mice

In 1992 outlaw fishing boats began illegally harvesting lobsters from the territorial waters of the country of Belukia. Soon after, the annual tonnage of lobster legally harvested in Belukian waters began declining; in 1996, despite there being no reduction in the level of legal lobster fishing activity, the local catch was 9,000 tons below pre-1992 levels. It is therefore highly likely that the outlaw fishing boats harvested about 9,000 tons of lobster illegally that year.
    Which of the following is an assumption on which the argument depends?
   A.The illegal lobster harvesting was not so expensive that the population of catchable lobsters in Belukia’s territorial waters had sharply declined by 1996
   B.The average annual lobster catch, in tons, of an outlaw fishing boat is has increased steadily since 1992.
   C.Outlaw fishing boats do not , as a group, harvest more lobsters than do licensed lobster-fishing boats.
   D.The annual legal lobster harvest in Belukia in 1996 was not significantly less than 9,000 tons.
   E.A significant proportion of Belukia’s operators of licensed lobster-fishing boats were out of business between 1992 and 1996

遇到一个CR GWD，参展电影那道
Background information: This year, each film submitted to the Barbizon Film Festival was submitted in one of ten categories. For each
category, there was a panel that decided which submitted films to accept.
Fact 1: Within each category, the rate of acceptance for domestic films was the same as that for foreign films.
Fact 2: The overall rate of acceptance of domestic films was significantly higher than that of foreign films.
In light of the background information, which of the following, if true, can account for fact 1 and fact 2 both being true of the submissions to this year’s Barbizon Film Festival?
   1. In each category, the selection panel was composed of filmmakers, and some selection panels included no foreign filmmakers.
   2. Significantly more domestic films than foreign films were submitted to the festival.
   3. In each of the past three years, the overall acceptance rate was higher for foreign than for domestic films, an outcome that had upset some domestic filmmakers.
   4. The number of films to be selected in each category was predetermined, but in no category was it required that the acceptance rate of foreign films should equal that of domestic films.
   5. Most foreign films, unlike most domestic films, were submitted in categories with high prestige, but with correspondingly low rates of acceptance.
