24-24 Many winemakers use cork stoppers; but cork stoppers can leak, crumble, or became moldy, so that those winemakers must often discard a significant proportion of their inventory of bottled wine. Bottlemaster plastic stoppers, which cannot leak, crumble, or mold, have long been available to winemakers, at a price slightly higher than that of traditional cork stoppers. Cork prices, however are expected to rise dramatically in the near future. Clearly, therefore, winemakers who still use cork but wish to keep production costs from rising will be forced to reconsider plastic stoppers. And since the wine-buying public’s association of plastic stoppers with poor-quality wine is weakening, there is an excellent chance that the Bottlemaster plastic stopper will gain an increased share of the market for wine-bottle stoppers.

In the argument given, the two portions in boldface play which of the following roles?

A)    The first is a judgment that has been advanced in support of a position that the argument opposes; the second is the main conclusion of the argument.

B)    The first is a judgment that has been advanced in support of a position that the argument opposes; the second is conclusion drawn in order to support the main conclusion of the argument.

C)    The first is the main conclusion of the argument; the second provides evidence in support of that main conclusion.

D)    The first is the main conclusion of the argument; the second is a restatement of that main conclusion.

E)    The first is a conclusion drawn in order to support the main conclusion of the argument; the second is that main conclusion.

I have no idea how to do bold faces? Please help!!!

I think D is the right one, but why E?

Look separately at the role that each BF part plays in the argument.  Then look at the answer choices.  Each answer choice has two components.  If and only both components are correct, the answer choice is correct.

Clearly in the passage, the main conclusion is the 2nd BF.  Therefore, B, C, D are out.  The 1st BF is an intermediary conclusion, so only E is correct.
