A company that manufactures plastic products from recyclable plastic is, surprisingly, unconcerned that economic conditions may worsen, despite analysts' belief that consumers would then consider ecofriendly plastic products an expensive luxury. But the company reasons that it will be able to lower its prices because, in a weakened economy, other ecofriendly plastic manufacturers are likely to fail. Demand among manufacturers for recyclable plastics as raw materials would then plummet, creating an oversupply of such materials, making them less expensive for the manufacturer to purchase and thus lowering the company's costs.
Which of the following, if true, most weakens the company's reasoning?
Smaller ecofriendly plastic manufacturers are more likely to fail in a weakened economy than larger ecofriendly manufacturers are.
Some retailers whose sales include various companies' ecofriendly plastic products have struggled in recent years despite the overall good economy.
Consumers would likely soon learn of the oversupply of recyclable plastics and cease recycling them, significantly raising manufacturers' raw-material costs.
Retailers, including retailers that cater to consumers seeking certain types of ecofriendly products, may lose some business if economic conditions worsen.
The plastics used by the company in its products were, after a recent investigation by a regulatory body, declared to be safe for consumers.
情景：一个用可回收塑料制造塑料产品的公司并不担心他们的经济前景会更坏，虽然说消费者可能会觉得这种产品略贵。但此公司认为在这种不景气的经济情况下，对手会倒闭，那么原材料就会供大于求，原材料价格也会降低，从而此公司的生产成本会下降，价格也可以降低。
推理：此题的逻辑链非常清晰，顺序的逻辑推理为：
经济不景气→对手倒闭→原材料供大于求→原材料价格降低→此公司成本下降→产品价格可降低→经济状况不会变坏
最终的结论（company’s reasoning）是“be able to lower its price”，所以我们要找到逻辑链前面一部分的gap来削弱这个结论。
选项分析：
A选项：在不景气的经济条件下小公司比大公司更容易倒闭：无关比较。和公司大小无关。我们讨论的是此制造公司到底能不能降低价格。
B选项：尽管总体经济形势不错，但一些销售各种环保塑料产品的零售商最近几年经营得不咋地：讨论的是此公司（manufacturer），与零售商无关。
C选项：正确。消费者会很快意识到环保塑料的过度供给，然后就停止重复利用，导致制造商的原材料成本上升：直接指出原材料的供大于求无法长久，最终还是会不可避免的供小于求，导致原材料成本上升。
D选项：如果经济形势不好，零售商（包括那些试着满足需要环保产品的消费者的零售商）可能会倒闭：与零售商无关。
E选项：最近的调查发现，那些被用在产品里的塑料是安全的：与材料安不安全无关。我们讨论的是此制造公司能不能降低价格。
题目里边的理由是：原材料会供大于求，材料价格下降。反驳的时候要针对这一点。
A 某些厂家怎么样，无关
B 某些零售商最近几年怎么样，无关
C 原材料价格会上涨，对的
D 零售商怎么样，无关
E 材料无毒，无关
