一道机经，求助，关于酒的塞子问题~

球球是我

    

一道机经的题目，我怎么觉得两句都是结论。。。。

谁能具体解释一下或者有确定答案？

谢谢~~谢谢~~~

红酒的塞子

    

【版本1】逻辑里面有一题是GWD上说红酒软木塞和塑料瓶塞的。黑体一句是说塑料瓶塞的优点，一句说很多人没有换塑料瓶塞。结论是很多人不仅仅是出于经济因素考虑来用瓶塞。我选的这两个都是支持的evidence,不知道对不对……有空考证一下

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.
