Hello!
Okay, so here is the question:
Based upon studies conducted over the last two decades that show head injuries can be reduced if children wear bicycle helmets, some jurisdictions have passed laws requiring that children under the age of 12 wear helmets when they ride their bicycles. - Even though a large number of children do wear bicycle helmets, more head injuries than expected are continuing to occur. And this is the result even though the studies have shown that the wearing a helmet reduces the incidence of head injuries.
Then it asks "which one of the following statements, if true, might suitably explain the unexpected finding"
So after reading the powerscore LR bible cover to cover i instinctively looked for the answer that suggested that accidents related to bicycles had gone up over all, meaning that whilst children wearing helmets had increased, so had the number of children riding bicycles overall increased, meaning the ones not wearing helmets also increased - which would account for the findings. Proving my assumption further, the stimulus states "Even though a large number of children do wear bicycle helmets, more head injuries than expected are continuing to occur" but does NOT state that injuries are continuing to occur to the children who are wearing the helmet! so from this we can safely assume that even though the number of helmet wearers has gone up, the number of head injuries have been the product of the increasing number of those who do not wear them.
so i found this answer
(b) "more children are riding bicycles now than before bicycle helmets were introduced"
This seemed to fit in with my assumption and if it were true, would make sense. If more children are riding bicycles now and the rate of growth of children riding bicycles without helmets exceeds those riding bicycles with helmets then it would account for the discrepancy between the findings and the expectations
However this was incorrect.The correct answer was
(E)"bicycle helmets do not work properly if they are not properly secured with the chin strap, and many children and their parents do not secure the chin strap properly"
I understand why E is correct so i don't need an explanation for that, however i do need an explanation for why b is not correct as i would've kept both of these 2 as contenders and more than likely gone with B. In fact I did. Thank you
