请问:
(一)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
(二)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.
(三)All Y chromosomes in existence today are descended from a single ancestor’s who is thought to have lived about 140,000 years ago.
A. a single ancestor’s who is thought to have lived
B. a single ancestor’s who was thought to live
C. a single ancestor whom it is thought had lived
D. the Y chromosome of a single ancestor who is thought to have lived
E. the Y chromosome of a single ancestor whom it was thought had lived
