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.
With this argument, Pedro offers several facts about the negative impact of disposable diapers to support his conclusion that people must stop buying them and switch to cloth diapers.
Maria points out the negative environmental impact of cloth diapers. Notice that she does not state that she disagrees with his conclusion. Perhaps she agrees but she feels his argument is incomplete.
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 favour of cloth diapers. -- Incorrect - Maria DOES NOT discuss disposable diapers
(B) indicating that Pedro draws a hasty conclusion, based on inadequate evidence about cloth diapers. - Correct - she points out that Pedro has forgotten certain evidence about cloth diapers being detrimental to the environment
(C) pointing out that there is an ambiguous use of the word "disposable" in Pedro's argument - Incorrect - there's no discussion of disposable diapers, and definitely no discussion of the word "disposable."
(D) demonstrating that cloth diapers are a far more serious threat to the environment than disposable diapers are - Incorrect
(E) suggesting that the economic advantages of cloth diapers outweigh whatever environmental damage they may cause - Incorrect
Answer B
