I was down to (B) and (E) on this one, and I ultimately chose (B) for the following reasons:
Okay, so we have a weaken question. The conclusion is that the privatization of the national parks would probably benefit park visitors as well. Why? Because a similar privatization of the telecommunications industry benefited consumers by allowing competition among a variety of telephone companies to improve service and force down prices.
I thought (B) would weaken the conclusion that the privatization WILL NOT benefit park visitors because the similar privatization of the telecommunications led to significantly increased unemployment and economic instability. (E) on the other hand, so what if it provides MUCH less competition? It could still provide enough and be able to benefit the park visitors. Since we are not told HOW MUCH competition is needed, I didn't think (E) necessarily weakened the argument.
Any thoughts???
