Here's the OA and OE -
Explanation: What would most weaken the argument above? The motorcyclists who oppose the legislation claim that they are free to take risks as long as they do not interfere with the safety or well-being of others. To weaken the argument, we need to contradict its reasoning. We need an answer choice showing that helmet wearing does affect the safety and well-being of others.
A) This could support the proposed legislation, but it does not show how other people can be harmed by some motorcyclists not wearing safety helmets. This could weaken an argument that helmets don’t reduce the risk of injury, but that is not what is being argued here.
B) Correct. This choice correctly identifies how not wearing helmets by some motorcyclists negatively influences the well-being of others. Since not threatening the well-being of others is a major part of the motorcyclists’ reasoning, contradicting this reasoning weakens the argument.
C) Requirements for construction workers are not relevant to the argument.
D) The argument did not state that motorcyclists cannot wear helmets, and the fact that they can does not weaken the argument about whether they should.
E) This statement shows that some people other than motorcyclists can be harmed by motorcycle accidents. Their injuries are not related to whether motorcyclists wear helmets, however, since helmets do not prevent accidents and in case of accident, protect only the motorcyclist. Since this statement provides no evidence that fewer accidents or non-cyclist injuries would occur if motorcyclists wore helmets, it does not weaken the argument.
