1. Since a rhinoceros that has no horn is worthless to poachers, the Wildlife Protection Committee plans to protect selected rhinoceroses from being killed by poachers by cutting off the rhinos’ horns.
The Wildlife Protection Committee’s plan assumes that
(A) poachers do not kill rhinos that are worthless to them
(B) hornless rhinos pose less of a threat to humans, including poachers, than do rhinos that have horns
(C) rhinos are the only animals poachers kill for their horns
(D) hornless rhinos can successfully defend their young against nonhuman predators(A)
(E) imposing more stringent penalties on poachers will not decrease the number of rhinos killed by poachers
2. Crimes are mainly committed by the young, and for this reason merely increasing the number of police officers or expenditures on police services has little effect on reducing the crime rate. In fact, the only factor associated with a crime-rate drop is a decrease in the number of people in the community aged fourteen to thirty.
The findings above can best serve as part of an argument against
(A) the likelihood that any law enforcement program will be effective in reducing the crime rate within a short time
(B) increasing prison terms for young people found guilty of crimes
(C) introducing compulsory military conscription for people aged seventeen to nineteen
(D) raising the age at which students are permitted to leave school(A)
(E) a community’s plan to increase the number of recreational and educational activities in which young adults can participate
3. A 20 percent decline in lobster catches in Maine waters since 1980 can be justifiably blamed on legislation passed in 1972 to protect harbor seals. Maine’s population of harbor seals is now double the level existing before protection was initiated, and these seals are known to eat both fish and lobsters.
Which of the following, if true, would most seriously weaken the argument above?
(A) Harbor seals usually eat more fish than lobsters, but the seals are natural predators of both.
(B) Although harbor seals are skillful predators of lobsters, they rarely finish eating their catch.
(C) Harbor seals attract tourists to Maine’s coastal areas, thus revitalizing the local economy.
(D) Authors of the 1972 legislation protecting harbor seals were convinced that an increase in that animal’s numbers would not have a measurably negative impact on the lobster catch.(E)
(E) The record lobster harvests of the late 1970’s removed large numbers of mature lobsters from the reproductive stock.
4. Politician: Fewer people are entering the labor market now than previously. If the economy grows, the demand for motivated and educated people will far outstrip the supply. Some companies have already started to respond to this labor-market situation by finding better ways to keep their current employees. Their concern is a sure indicator that the economy is growing.英语作文
