### HideShow timer Statistics

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 containers are discarded than when comparable nonbiodegradable containers are discarded.

Which of the following, if true, most strengthens the argument above?

(A) Both partially biodegradable and nonbiodegradable plastic beverage containers can be crushed completely flat by refuse compactors.
(B) The partially biodegradable plastic beverage containers are made with more plastic than comparable nonbiodegradable ones in order to compensate for the weakening effect of the bounding agents.
(C) Many consumers are ecology-minded and prefer to buy a product sold in the partially biodegradable plastic beverage containers rather than in nonbiodegradable containers, even if the price is higher.
(D) The manufacturing process for the partially biodegradable plastic beverage containers results in less plastic waste than the manufacturing process for nonbiodegradable 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.

B it is...

any point that proves that biodegradable containers will yield as much as or more plastic than non-bio... container will be the answer.

The other answers are either out of scope and unrelated or contradictory.

Can anyone pls explain..How 'B' strengthens the argument...

B - is an assumption.

The argument talks about 'plastic refuse'

no less plastic refuse per container is produced when such containers are discarded than when comparable nonbiodegradable containers are discarded.

I will go for 'D'. It reinstates the above argument with a more clearer definition.

The conclusion of the argument says : you do not throw less plastic away with the bio one than with the normal when you discard them. But to explain this it only says that plastic and cornstarch are used, it does not say that more plastic is actually in the bottle. But B tells us that !
So B does strengthens the argument.

I also did not have the right vision before Veritas prepcourse, but a very important point is that an assumption strengthens an argument. Even if it only strengthens it a little bit, if it is the one which stengthens it the more compared to the other 4, it is enough.

D tells us about the waste of plastic during the manufacturing process, not about the plastic of the bottle itself, on which you should focus, as the argument focuses on the refuse (=garbage) => D is out of scope.

If I remember correctly, I think the OA is B because even though product is partially biodegradable, more plastic was used to make it

Thanks guys.

OA is B.

OE:

The information that strengthens the arguement will be about the subjects of the arguement, not about tangential issues. In this case, discovering that the partially biodegradable containers use more plastic than comparable non-biodegradable one in order to compensate for the weakness of the biodegradable bonding agent would strengthen the arguement.

Need help in understanding the content of the argument & also explain every answer choice.

The difficulty here is that the argument stresses that there is NO INHERENT BENEFIT to this type of bottle.

Thus, STRENGTHENING is something to say that this type of bottle is BAD (B).

Weakening would be to say that it is good (D).

A) is Out of Scope because it talks about being crushed flat, not waste per bottle as in the argument.

C) is Out of Scope because it is about customer preference, not about amount of waste per bottle.

E) is Out of Scope because it is about HOW the bottle will be reused, not the amount of waste per bottle.

Premise: Since only the bonding agent degrades, leaving the small bits of plastic
Conclusion: no less plastic refuse per container is produced when such containers are discarded than when comparable nonbiodegradable containers are discarded. --> So, we need an asnwer choice that says Plastic in Bio => Plastic in NON-Bio -> (B) gives us such Information.

B) The partially biodegradable plastic beverage containers are made with more plastic than comparable nonbiodegradable ones in order to compensate for the weakening effect of the bounding agents.
