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--------.
(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
(B) even those bicyclists who regularly wear helmets have a poor understanding of the degree and kind of protection that helmets afford
(C) a helmet that included protection for the temples would have to be somewhat larger and heavier than current helmets
(D) the bone in the temple area is relatively thin and impacts in that area are thus very likely to cause brain injury
(E) bicyclists generally land on their arm or shoulder when they fall to the side, which reduces the likelihood of severe impacts on the side of the head
题目分析：这个题目问的非常具体，就是如果这个头盔能保护那个地方，这个头盔就会有用的原因，A说只有一小部分是带头盔的，都不带这个头盔还有什么用，干掉。B说即使经常带头盔的也不了解头盔，和问题不搭界。干掉。C说头盔大小和头盔重量问题，扯得就更远了，干掉。D说头盔那个要保护的地方比较脆弱会导致比较严重的受伤，我正好保护这个地方，那就说明这个头盔靠谱。留着。E说摔倒经常用什么部位着地，减少脑部受伤，这个和我问题要求的头盔需要保护那个地方，这个头盔才会靠谱这个问题连不上，干掉。
