Can someone explain why D is less supported than C? I'm really having trouble here.
I guess that C is the sort of "everyday logic" answer that they are probably looking for out of the third question in a section. But because of the way it's worded it seems to me that picking choice C means interpreting "sufficient" to mean "more," an unsupported inference.
On the other hand, if we take "sufficient" to only mean sufficient choice D is supported.
David says: it's unfair to forbid companies from hiring permanent replacements because it would lead to companies having little leverage in negotiations with strikers.
Lin says: "no," i.e. it is not unfair, because regardless of any reduction companies would still have sufficient leverage if they hired temporary workers.
Choice D says that the disagreement is based on how much leverage companies should have. David thinks it's unfair, thus wrong, for companies to end up with "little leverage." Lin says that's not true because the companies could still have "sufficient" leverage." That's my interpretation.
Choice C says they disagree over the amount lost as a result of not being able to hire permanent replacements. David of course says the amount would be big because companies end up with little (although this is actually a big inference because even though he says they end up with little that doesn't mean hiring permanent replacements would have given them HUGE leverage and not being able to hire is therefore is a BIG LOSS--it could be that they have a medium amount and the inability to hire permanent replacements makes them go from a medium amount to "a little.")
Regardless of that, Lin simply says that the companies would still have sufficient leverage anyway. For C to be correct we have to assume that by saying "sufficient" Lin is saying the amount lost is small; on the other hand, he could be saying that the amount lost is big, but that nevertheless it's still sufficient.
Can someone point out where I've gone wrong here? The only thing I see is maybe the "unfair"=wrong issue. But even given that my qualms with C seem pretty serious--I don't see how we can go from Lin saying "the companies would still have sufficient leverage" to Lin saying, as choice C would require, that the loss is small (or at least smaller than David thinks). It would require an assumption regarding what sufficient means to Lin. And that clearly seems like a value judgment regarding how much leverage he thinks companies should have against striking employees.
