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.

Stimulus: Although wood burning stoves are most efficient than open fire paces they are also more dangerous. The smoke that wood burning stoves release up the chimney is cooler than the smoke from the open flame thus it travels more slowly and deposits more creosote a flammable substance that could clog a chimney it or ignite in it.

IMO C it states that open fire produce more severe accidents than wooden stoves.


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.

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

Ok, alright - I looked again and saw that Steve previously addressed you about Q11 in another post, so it must be Q25 you are getting some information about here.

In this inquiry, the creator reveals to us that wood consuming ovens are "increasingly perilous" than open chimneys. He at that point enlightens us regarding creosote stores - wood consuming ovens store more creosote than open chimneys, and creosote is risky in light of the fact that it can obstruct a fireplace and even reason a fire inside the stack. That sounds risky!

To debilitate this contention, we again need to recognize and concentrate on the end. That is in the initial sentence - he is attempting to demonstrate that wood consuming ovens are increasingly risky. Our prephrase could be as basic as "no they aren't", yet since he told us one way that makes the ovens increasingly risky, we may have an all the more remarkable prephrase if we somehow managed to state "in some other way, chimneys are progressively perilous". Anything that demonstrates chimneys to be more risky than wood ovens will debilitate the contention introduced by the check here.

Answer C is the one in particular that presents chimneys as being progressively hazardous - they represent a more serious danger of extreme mishaps in the home. It's not about creosote by any stretch of the imagination - it's a very surprising risk. That answer doesn't obliterate the contention - creosote may in any case be the greatest risk out there - however it doesn't need to wreck it, it just needs to debilitate it, and it does that.

Answer B doesn't present a chimney related risk, which is the thing that we truly need here. Rather, it discusses creosote all the more for the most part, and it gives us data that could apply similarly to ovens and chimneys. That won't help us to subvert the case that, of the two, ovens are increasingly hazardous.

I trust that cleared things up!

Efficient and Dangerous: wood-burning stoves > open fireplaces

1) The smoke that wood-burning stoves release up the chimney is cooler than the smoke from an open flame.
2) Thus it 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. ( No parameter given to determine that wooden burning stoves produces less creosote than open fireplaces.) (OUT of Scope)

(B) The amount of creosote produced depends not only on the type of flame but on how often the stove or fireplace is used. (Nothing mentioned regarding the usage and type of flame, Irrelevant)

(C) Open fireplaces pose more risk of severe accidents inside the home than do wood-burning stoves. (This weakens the argument as even though wooden stoves might process more creosote, it's still safer than using open fireplaces in home) (Correct)

(D) Open fireplaces also produce a large amount of creosote residue. (Same as A, no parameter given to determine the production of creosote residue) (incorrect)

(E) Homeowners in warm climates rarely use fireplaces or wood-burning stoves. (No such data given) (out of scope)

Answer is C

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. - WRONG. Still the claim in blue text holds.

(B) The amount of creosote produced depends not only on the type of flame but on how often the stove or fireplace is used. - WRONG. 2nd best option here.

(C) Open fireplaces pose more risk of severe accidents inside the home than do wood-burning stoves. - CORRECT. So, fire inside the chimney is safer than the open fireplaces.

(D) Open fireplaces also produce a large amount of creosote residue. - WRONG. Irrelevant.

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

Answer C.
