One variety of partially biodegradable plastic beverage [#permalink]
 15 Jan 2008, 14:33
Question Stats:
0% (00:00) correct
 0% (00:00) wrong based on 1 sessions
One variety of partially biodegradable plastic beverage container is manufactured from small bits of plastic bound together by a degradable bonding agent such as cornstarch. Since only the bonding agent degrades, leaving the small bits of plastic, no less plastic refuse per container is produced when such container are discarded than when comparable nonbiodegradable containers are discarded.
Which of the following, if true, most weak strengthens the arguement above?
(A)Both partially biodegradable and non-biodegradable plastic beverage containers can be crushed completely flat by refuse compactors.
(B)The partially biodegradable plastic beverage container are made with more plastic than comparable nonbiodegradable ones in order to compensate for the weakening effect of the bonding agents.
(C)Many consumers are ecology-minded and prefer to buy a product sold in partially biodegradable plastic beverage containers rather than in nonbiodegradable containers, even if the price is higher.
(D)The manufacturing process for partially biodegradable plastic beverage containers results in less plastic than the manufacturing plastic beverage containers.
(E) Technological problems with recycling currently prevent the reuse as food or beverage containers of the plastic from either type of plastic beverage container.
help me understand the question please. this makes me irritate because most of the time i mark wrong answers. can nybody help me out in these type of questions.
-thanx

Conclusion: Biodegradable (B) and non- biodegradable (NB) containers generate same amount of plastic waste per container
Weakens conclusion:
(A)Both partially biodegradable and non-biodegradable plastic beverage containers can be crushed completely flat by refuse compactors [The argument is about plastic waste per container (Biodegradable (B) and non- biodegradable (NB)). Therefore this is completely irrelevant to the argument – Eliminate it]
(B)The partially biodegradable plastic beverage container is made with more plastic than comparable non-biodegradable ones in order to compensate for the weakening effect of the bonding agents [weakens the argument that both B and N-B generates same waste per container - hold it].
(C)Many consumers are ecology-minded and prefer to buy a product sold in partially biodegradable plastic beverage containers rather than in non-biodegradable containers, even if the price is higher. [This argument is not about consumer buying habits – Eliminate it]
(D)The manufacturing process for partially biodegradable plastic beverage containers results in less plastic than the manufacturing plastic beverage containers. [This argument is not about manufacturing process of Biodegradable OR non- biodegradable – Eliminate it]
(E) Technological problems with recycling currently prevent the reuse as food or beverage containers of the plastic from either type of plastic beverage container. [ Technological usage or problems are definately out of the scope of the argument – Eliminate it]
Answer: B

-thanx we must find a reason for what both types generate the same plastic refuse. I was tricked by E because the result is that recycling doesn't occurr...but we care for only the amount of plastic, thus B is best.

The question is wrong.
"Most weak strengthens the argument?"
What is weak strengthen?
If its strengthen - then the answer is B
If its weaken - then the answer is D

Weakens:
Conclusion is that " no less plastic refuse per container is produced when such container are discarded than when comparable nonbiodegradable containers are discarded."
"D": This indicates that the conclusion isn't true, because for partially biodegradable plastic beverage containers results in less plastic than the manufacturing plastic beverage containers. So it's not same as the conclusion says.
Strengthens:
Conclusion is that " no less plastic refuse per container is produced when such container are discarded than when comparable non biodegradable containers are discarded."
"B": This supports the conclusion that using partially biodegradable plastic beverage containers is not going to result in less plastic refuse because already it needs more plastic in order to compensate for the weak bonding agents.
Please Post the OA.

I think "comparable nonbiodegradable" is not the same as "manufacturing plastic". The latter one does not say whether it is biodegradable or not? It is out side of the comparison here.
