感谢LZ！请问是这题么？是不是变体？还是原题？
一道BF是关于wine外包装的，我在GWD 上看到，但考得是变体。主要是说，原来的外包装成本上升，因此厂商若要提高竞争力就只有将外包装换成plastic的。但后面又说由于现在并没有看到用plastic的厂商数增加，结论是厂商并非完全根据利益行动。后面一句划线部分具体内容不记得了，总之是排除了一个除利润之外的他因导致厂商不用plastic外包装。答案我选的E，也就是第一个是结论，第二个排除了一个他因以支持结论。

GWD参考：GWD-24-Q 24:
Many winemakers use cork stoppers; but cork stoppers can leak, crumble, or becomemoldy, so that those winemakers must often discard a significant proportion of theirinventory 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 inthe near future. Clearly, therefore,
winemakers who still use cork but wish to keepproduction costs from rising will be forced to reconsider plastic stoppers. Andsince the wine-buying public’s association of plastic stoppers with poor-quality wineis weakening,
there is an excellent chance that the Bottlemaster plastic stopperwill 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 theargument opposes; the second is the main conclusion of the argument.

C. The first is the main conclusion of the argument; the second provides evidencein support of that main conclusion
D. The first is the main conclusion of the argument; the second is a restatementof that main conclusion.
E. The first is a conclusion drawn in order to support the main conclusion of theargument; the second is that main conclusion.
本题答案E，请大家注意狗主人说是变体。
