Pedro: Unlike cloth diapers, disposable diapers are a threat [#permalink]

100% (01:57) wrong based on 1 sessions
Pedro: Unlike cloth diapers, disposable diapers are a threat to the environment. Sixteen billion disposable diapers are discarded annually, filling up landfills at an alarming rate. So people must stop buying disposable diapers and use cloth diapers.
Maria: But you forget that cloth diapers must be washed in hot water, which requires energy. Moreover, the resulting wastewater pollutes our rivers. When families use diaper services, diapers
must be delivered by fuel-burning trucks that pollute the air and add to traffic congestion.
Maria objects to Pedro's argument by
(A) claiming that Pedro overstates the negative evidence about disposable diapers in the course of his argument in favor of cloth diapers.
(B) indicating that Pedro draws a hasty conclusion, based on inadequate evidence about cloth diapers.
(C) pointing out that there is an ambiguous use of the word "disposable" in Pedro's argument
(D) demonstrating that cloth diapers are a far more serious threat to the environment than disposable diapers are
(E) suggesting that the economic advantages of cloth diapers outweigh whatever environmental damage they may cause
Choosing D would need an implicit assumption. I will go with B because of the word "but you forget" meaning something related to haste.
I am sure GMAT will not hav such a question as B also can be refuted.
This is a subtle question.
I would go with D because B says that Pedro provides inadequate evidence about cloth diapers. However, Pedro does not give any evidence as to cloth diapers. He only mentions the cons of disposable diapers. Therefore, B can be refuted in that sense
D can also be negated because Maria does not really mention how cloth diapers are far more serious a threat than disposable diapers are. She just mentions that cloth diapers represent a threat to the environment but never establishes the magnitude of one's danger over another. Yet, as I previously mentioned, Pedro never mentioned any evidence about cloth diapers. Both B and D can each be refuted and this means that actually none of the answer should really be good.
Well my final answer is B. In drawing conclusion Pedro uses insufficient evidence and hence B should be correct. There is nothing mentioed about the threat or comparitive threat. Both the answers mention negatives about the both types of uses but we cannot realize that one diaper is a threat and the other is not.
Pedro draws a hasty conclusion insofar as he concludes they are not a threat to the environment, without considering all the evidence (which is conveniently supplied by Mary). Hence his evidence (of which none was supplied) was insufficient.
