I don't agree with the OA. I just want to see what you guys come up with before I disclose the OA. Please don't forget your explanations. Thanks

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

D for me as well.

She didn't say anything mentioned in A,B,C,E.
She gave reasons why cloth diapers threathen the environment. So I choose D

I chose B, go me

D is wrong because she doesnt mention disposable diapers at all, she talks about diaper services and how bad cloth diapers are

B is the OA? I would still go with D.

I said B as well.
(B) indicating that Pedro draws a hasty conclusion, based on inadequate evidence about cloth diapers
Hasty is a good keyword...The text says, "BUT YOU FORGET", suggesting a hasty solution.

(D) demonstrating that cloth diapers are a far more serious threat to the environment than disposable diapers are
D is way to extreme...nobody said it was a serious threat.

Okay, after reading it again, I agree it is B.
Good one.

Wow!! pretty tricky question, I chose myself D initially but after reading post B makes sense. Can anyone suggest some trick/tips to solve questions likes this?
