Question

Based on comprehensive longitudinal studies of accident prevention, several states have passed laws requiring children under the age of 18 to wear helmets when they roller blade. Yet a surprising result has been observed. Even though a large number of children wear helmets while roller skating, more head injuries than expected have been reported. This result persists, even though the studies have clearly shown that wearing a helmet reduces the incidence of head injuries.

Which of the following statements, if true, best explains the unexpected finding?

(A) A large number of parents are not complying with the law regarding helmets for their children
(B) More children are roller skating now than when the helmet law was introduced
(C) More accidents are reported now, in compliance with state insurance laws
(D) Many children do not properly secure the helmet's chin strap, and the helmet does not work properly 
(E) Helmets were not designed to prevent all head injuries, so it is not surprising that they still occur

Question type: Resolve paradox

(A)  A large number of parents are not complying with the law regarding helmets for their children  -  it does not really matter as we've been already said that "a large number of children wear helmets while roller skating"  
(B)  More children are roller skating now than when the helmet law was introduced  -   this information is also not really relevant, as the argument states that "more head injuries than  expected  have been reported"; future expectations very likely takes into account that the number might increase/decrease   
(C)  More accidents are reported now, in compliance with state insurance laws  -  I chose this option, even though it appears incorrect choice.  
(D)  Many children do not properly secure the helmet's chin strap, and the helmet does not work properly  -  correct choice; it does explain why even when helmets are present, they do not function as expected and do not prevent injuries  
(E)  Helmets were not designed to prevent all head injuries, so it is not surprising that they still occur  -  the argument does not states that helmet prevent  all ; watch for extreme language
 
 Bunuel , thanks for good number of new CR questions posted recent few days. Appreciate a lot!

May be this piece of text "This result persists" explains why (D).

fireflyejd1 · Answer

Why will C not be the right answer? if more accidents are being reported now than before, this shows clear causation for why more accidents are being reported now.

Kdodain · Answer

Option D is correct becoz it gives a genuine reason for helmet not able to prevent accidents.

But Why option C is incorrect?
Cause it's right if more accidents are reported now than before the number will surely increase in records even though it's proven that helmet prevents accidents

Option C is out of scope in terms of resolving the stated paradox

This result persists,  even though the studies have clearly shown that wearing a helmet reduces the incidence of head injuries.

we have to find the reason which solves the paradox that why nu of accident is not decreasing despite taking the counter-measure of wearing a helmet.

D clarifies that it is so because the helmet is not being worn properly and hence its not serving the helmet's intended purpose.

Hope this helps

C does not completely resolve the paradox. It doesn't tell us how many more accidents are being reported now. It could be just 2% of cases more.

On the other hand, D does a better job by explaining that most children are not wearing their helmets correctly. Even though a large number are wearing helmets, most are not properly securing them

sharad05 · Answer

Hi,

I still have a confusion between C and D.

Option D states that helmets are not being worn properly, so even if I assume most helmets are now useless, the number of total cases still should not 'exceed' the expected number.

While option C is giving a clear reason why the number goes higher than expected.

Any thoughts on this?

PoojanB · Answer

Hi  sharad05 
Question type is resolve the paradox
and the paradox says despite people wearing helmets, cases are increasing.

Option C says "More accidents are reported now, in compliance with state insurance laws" it states to the condition of an increase in cases but nowhere it hints towards resolving the paradox
Option D on the contrary gives strong reason stating that people are not wearing helmet properly and thats why accidents number are rising. Hence D is better choice than C
Hope this helps

Cheers to another good one! Btw, I got this wrong as I fell into the trap but let me reason out the logic to help others on this one.

Based on comprehensive longitudinal studies of accident prevention, several states have passed laws requiring children under the age of 18 to wear helmets when they roller blade. Yet a surprising result has been observed . Even though a large number of children wear helmets while roller skating, more head injuries than expected have been reported. This result persists, even though the studies have clearly shown that wearing a helmet reduces the incidence of head injuries.

Which of the following statements, if true, best explains the unexpected finding?

Initial thought: the reporting of more injuries than expected was a surprising result—something unexpected might have happened. Let us see what it could be

(A) A large number of parents are not complying with the law regarding helmets for their children [Out of scope, the paradox is why more injuries than expected have been reported despite ppl wearing helmets. If they dont wear helmets, it cannot explain the paradox]

(B) More children are roller skating now than when the helmet law was introduced [This would have been a good explanation if it said "more children than expected were skating" but stated as is we dont know if the increase was not-expected so it cannot explain the paradox]

(C) More accidents are reported now, in compliance with state insurance laws [Out of scope, the paradox is why more injuries than expected have been reported despite ppl wearing helmets. Although here we have more reports coming in we dont know if the skaters are wearing helmets or not. So it doesnt really give us the required reason to fill the gap or explain the paradox] Btw I fell for this trap choice as well, I ended up extending the statement (had done it subconsciously), thinking people are now more likely to report instances.

(D) Many children do not properly secure the helmet's chin strap, and the helmet does not work properly [Bingo, so despite actually wearing helmets the injuries happened and that is because the helmets didnt work as intended, paradox resolved]

(E) Helmets were not designed to prevent all head injuries, so it is not surprising that they still occur [Out of scope, we dont care about all head injuries]

Hope this is helpful

YashYashkratos · Answer

Picked D because i thought it would be right in the question makers eye.

however it does not explain WHY THE INCREASE IN HEAD INJURIES

MY BEST SHOT AT WHAT IT MEANS - i might be overdoing it with the explanation but i guess THE REASON MIGHT BE THAT KIDS WEAR THE HELMET AND DO MORE RISKIER ACTS however seems a little too extreme of a reason.
