15. Eight years ago hunting was banned in Greenfield County on the grounds that hunting endangers public safety. Now the deer population in the county is six times what it was before the ban. Deer are invading residential areas. Damaging property and causing motor vehicle accidents that result in serious injury to motorists. Since there were never any hunting=related injuries in the county, clearly the ban was not only unnecessary but has created a danger to public safety that would not otherwise exist.
Which one of the following, if true, provides the strongest additional support for the conclusion above?
(A) In surrounding counties, where hunting is permitted, the size of the deer population has not increased in the last eight years.
(B) Motor vehicle accidents involving deer often result in damage to the vehicle, injury to the motorist, or both.
(C) When deer populations increase beyond optimal size, disease and malnutrition become more widespread among the deer herds.
(D) In residential areas in the county, many residents provide food and salt for deer.
(E) Deer can cause extensive damage to ornamental shrubs and trees by chewing on twigs and saplings.
Answer: A 但我觉得B好象更对作者: kuuiytt 时间: 2004-8-26 12:50
1。B错的原因是：问题要additional support ，B所说的Motor vehicle accidents 在原文已作为证据提出，所以不是additional 2。A对的原因：作对比论证，说明DEER 数量增加的原因是BAN，而原文已知DEER数量的增加已对公共安全造成危害。故为答案。
