                                    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 _________.                                    

                                    

• Aamong 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
• Beven those bicyclists who regularly wear helmets have a poor understanding of the degree and kind of protection that helmets afford
• Ca helmet that included protection for the temples would have to be somewhat larger and heavier than current helmets  
• Dthe bone in the temple area is relatively thin and impacts in that area are thus very likely to cause brain injury
• Ebicyclists 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

不觉得题目有什么逻辑漏洞啊，为什么还需要加前提……求大神解救……

楼主其实不用把这道题一定归类为assumption 题型（如果一定要给这个题分类的话，个人觉得strengthen 题型更适合），正确选项只要能把题目解释清楚就好了。

前提一：现有头盔无法保护太阳穴；前提二：大多数事故都是由于太阳穴受伤导致。结论：头盔保护太阳穴的话受伤就会大大下降，因为——————————

D选项：因为太阳穴附近的骨头太脆弱，容易导致脑损伤。而其他选项基本上都无关。
