Many winemakers use cork stoppers; but cork stoppers can leak, crumble, or become 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 marked 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 a 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.

答案是E, 本来选D,仔细读了一下, 觉得解释应该是：
段落讲了三层内容，一：plastic比cork 保持性好；二：虽然以前plastic价格高，但是Cork有涨价的趋势 （子结论：考虑价格因素的人会逐步替换到cork）；三：plastic质量问题不断弱化， 最终结论：plastic会gaining share

最后的两句话（clear 和therefore后面）不是有and连接应该算并列的吧，怎么确定一个是conclusion另一个是main conclusion呢？

笨蛋加油
