标题: og13-cr101求解....... [打印本页] 作者: jsongdi 时间: 2013-7-11 21:24 标题: og13-cr101求解....... Which of the following most logically completes the argument?
The irradiation of food kills bacteria and thus retards spoilage.However,it also lowers the nutritional value of many foods.For example,irradiation destroys a significant percentage of whatever vitamin B1 a food may contain.Proponents of irradiation point out that irradiation is no worse in this respect than cooking.However,this fact is either beside the point,since much irradiated food is eaten raw,or else misleading,since_____________.
(A) many of the proponents of irradiation are food distributors who gain from foods' having a loger shelf life
(B) it is clear that killing bacteria that may be present on food is not the only effect that irradiation has
(C) cooking is usually the final step in preparing food for consumption,whereas irradiation serves to ensure a longer shelf life for perishable foods
(D) certain kinds of cooking are,in fact,even more destructive of vitamin B1 than carefully controlled irradiation is
(E) for food that is both irradiated and cooked,the reduction of vitamin B1 associated with either process individually is compounded

Springfield Fire Commissioner:The vast majority of false fire alarms are prank calls made anonymously from fire alarm boxes on street cors.Since virtually everyone has access to a private telephone,these alarm boxes have outlived their usefulness.There fore,we propose to remove the boxes.Removing the boxes will reduce the number of prank calls without hampering people's ability to report a fire.
Which of the following,if true,ost strongly supports the claim that the proposal,if carried out,will have the announced effect?
(A) The fire department traces all alarm calls made from private telephones and records where they came from.
(B) Maintaining the fire alarm boxes costs Springfield approximately $5 million annually.
(C) A telephone call can provide the fire department with more information about the nature and size of a fire than can an alarm placed from an alarm box.
(D) Responding to false alarms significantly reduces the fire department's capacity for responding to fires.
(E) On any given day,a significant percentage of public telephones in Springfield are out of service.
答案是A。。。
那C呢..? 不是很理解。。。。。
灰常感谢......弱弱再问一下第二题关于A的解释是If prank calls from private telephones are traced back to their origin,that should deter people from making suck calll.....应该怎么去理解呢......还有..C选项呢....?作者: enkyklios 时间: 2013-7-11 22:54

不过看了你的解释之后,我有个小小的问题
这句话“Proponents of irradiation point out that irradiation is no worse in this respect than cooking.”一直让我觉得他们的意思是指“单irradiation和单cooking破坏B1的程度是差不多的”。你说的是“一个食物经过了射线照射,又经过了cooking你怎么知道那个破坏的维B1多一点?你怎么比较出来的破坏作用差不多?”,那么,难道食物一定需要经过irradiation再cooking吗?也是可以不经过irradiation而直接cooking的吧?那他们的话有什么misleading的呢?这个题目又没有前提说“food一定要先irradiation才能cooking”
