Although wood-burning stoves are more efficient than open fireplaces, they are also more dangerous. The smoke that wood-burning stoves release up the chimney is cooler than the smoke from an open flame. Thus it travels more slowly and deposits more creosote, a flammable substance that can clog a chimney—or worse, ignite inside it.

Which one of the following, if true, most seriously weakens the augment?

(A) The most efficient wood-burning stoves produce less creosote than do many open fireplaces.

(B) The amount of creosote produced depends not only on the type of flame but on how often the stove or fireplace is used.

(C) Open fireplaces pose more risk of severe accidents inside the home than do wood-burning stoves.

(D) Open fireplaces also produce a large amount of creosote residue.（C）

(E) Homeowners in warm climates rarely use fireplaces or wood-burning stoves.

文中说：两种Stove(open fire和wood)

因为Wood stove更容易形成一个负影响的C，所以WS 比OF S更加危险

要反对

C的确可以说明这个结论不对，但是是位于这个逻辑链外面的呀，并不能反对这个argument啊

为什么D不对呢？的确这个large amount of C 看上去不好，因为没有和Wood stove产生的C进行比较，但是至少还是和这个逻辑链有关的呀？

难道我好不容易建立起来的有关无关感觉是错的？

谢谢
