. Lobster 那道。 GWD原题….
   T-7-11
   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
答案是什么?是A吗?
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
