兔子这题,求确认 是不是原题 还是变体,怎么变的啊 Rabbits were introduced to Numa Island in the nineteenth century. The government proposes to reduce the population by using a virus that has caused devastating epidemics in rabbit populations elsewhere. But the virus will have a little(有这个词)infection on the bilby. The government’s plan, therefore, may serve the interests of agriculture. Which of the following, if true, most seriously weakens the argument? A. There is less chance that the virus will infect domestic animals on Numa than that it will infect bilbies. B. There are no species of animals on the island that prey on the rabbits. C. Overgrazing by rabbits endangers many of the plants on which bilbies feed.(Answer) D. The virus that the government proposes to use has been successfully used elsewhere to control populations of rabbits. E. There must be some alternative means of reducing the rabbit population that would involve no threat to the bilby. -- by 会员 jenny1989 (2010/10/30 22:52:51)
