题目
After recent hurricanes produced tremendous damage there, Mardin County revised its building code. In doing so, Mardin imposed stricter standards for roofing but not for windows. The revision will undoubtedly reduce the principal cause of property damage, namely rainwater coming through damaged roofs. However, the revision will do little to prevent personal injuries , since, while many injuries are caused by flying debris breaking through windows, very few are caused by roof collapse or rainwater.
Which of the following, if true, most seriously weakens the argument?
选项
A.For many years Mardin County’s building code has imposed a stricter standard for windows than that imposed by most counties that are frequently struck by hurricanes.
B.The hurricanes that recently hit Mardin County were not as severe as some hurricanes that have hit there in the past 100 years.
C.Much of the flying debris carried by the winds of a hurricane is roof material that has become dislodged.
D.During a hurricane, broken windows in a house cause increased pressure inside the house that can, in turn, cause the roof of the house to become damaged.
E.Mardin County’s building code applies to the repair of houses in addition to the construction of new houses.
解析
在最近的飓风在马尔丁县(Mardin County)造成巨大破坏之后,马尔丁县修改了其建筑规范。在此过程中,马尔丁对屋顶制定了更严格的标准,但对窗户没有。这一修订无疑将减少财产损失的主要原因,即通过受损屋顶进入的雨水。然而,这一修订对防止人身伤害作用不大,因为虽然许多伤害是由飞散物冲破窗户造成的,但很少是由屋顶坍塌或雨水造成的。
- **论点**:马尔丁县对屋顶建筑规范更严格的修订对防止人身伤害作用不大。
- **论据**:许多人身伤害由飞散物冲破窗户导致,很少由屋顶坍塌或雨水导致。
- **正确答案方向**:要削弱该论证,正确答案应表明对屋顶建筑规范的修订其实能对防止因窗户被冲破而导致的人身伤害有一定作用,或者能建立起屋顶与窗户在造成人身伤害方面的某种关联。
- **A选项**:多年来,马尔丁县的建筑规范对窗户的标准比大多数经常遭受飓风袭击的县都要严格。此选项讨论的是马尔丁县窗户标准与其他县的比较,与此次对屋顶规范的修订能否防止人身伤害无关,不能削弱,排除。
- **B选项**:最近袭击马尔丁县的飓风没有过去100年中袭击该地的一些飓风那么严重。飓风的严重程度与对屋顶规范的修订能否防止人身伤害没有直接关联,不能削弱,排除。
- **C选项**:飓风中许多飞散物是被吹走的屋顶材料。该选项表明造成人身伤害的飞散物(窗户被冲破的原因)很多是来自屋顶材料,那么加强屋顶的标准就有可能减少飞散物,从而对防止人身伤害有作用,有力地削弱了论点,当选。
- **D选项**:在飓风中,房屋中破碎的窗户会导致屋内压力增加,进而可能导致屋顶损坏。此选项主要说明窗户破碎对屋顶的影响,但没有表明加强屋顶标准能对防止人身伤害起到作用,无法削弱,排除。
- **E选项**:马尔丁县的建筑规范除了适用于新建房屋外还适用于房屋的修缮。该选项只是关于建筑规范的适用范围,与对屋顶的修订能否防止人身伤害这一话题无关,不能削弱,排除。
综上所述,正确答案是C选项。
