Which of the following most logically completes the passage?
Most bicycle helmets provide good protection for the top and back of the head, but little or no protection for the temple regions on the sides of the head. A study of head injuries resulting from bicycle accidents showed that a large proportion were caused by blows to the temple area. Therefore, if bicycle helmets protected this area, the risk of serious head injury in bicycle accidents would be greatly reduced, especially since ______________________.
大部分自行车头盔能够很好的保护都得顶部和后部，但是且不能为头部两侧的颞部提供保护。一个自行车车祸造成头部受伤的研究显示，大部分的受伤都是由于颞部的撞击引起的。所以，如果自行车头盔能够保护这个区域的话，在自行车车祸中受伤导致头部严重受伤的风险会被大大降低，因为________________
(A) among the bicyclists included in the study’s sample of head injuries, only a very small proportion had been wearing a helmet at the time of their accident
在那些研究调查的自行车手当中，只有很小的一部分在出车祸的时候戴了头盔。
(B) even those bicyclists included who regularly wear helmets have poor understanding of the degree and kind of protection that helmets afford
即便是那些骑自行车经常带头盔的人对于头盔的保护能力也知之甚少。
(C) a helmet that included protection for the temples would have to be somewhat larger and heavier than current helmets
一个可以保护颞部的头盔比现在的头盔更大并且更沉。
(D) the bone in the temple area is relatively thin and impacts in that area thus very likely to cause brain injury
颞部的骨头相对较薄，对这个区域进行撞击很容易对大脑造成伤害。
(E) bicyclists generally land on their arm or shoulder when they fall to the side, which reduces the likelihood of sever impacts on the side of the head
骑自行车的人在出车祸的时候通常倒向一边压在他们的胳膊或者是肩膀上，这样会降低对头不造成伤害的可能性。
解析：
A 如果在调查的时候只有一小部分是戴了头盔的，那么文章中所得出的结论就不正确，并不一定是没有保护好颞部才导致的头部受伤，那么做出新的头盔也不一定降低头部受伤的风险。
B 人们了不了解头盔的保护能力和能否降低头部受伤的风险没有任何关系，无关选项。
C 头盔的重量和体积与需要解释的内容无关。
D 很好的解释了为什么颞部受到撞击容易导致头部受伤，也就加强了新的头盔可以降低头部受伤的概率的结论。正确答案。
E 人们会不会经常伤到头部和头部受伤是不是由于颞部受伤引起的没有关系，无关选项。 |
