### HideShow timer Statistics

When glass products are made from recycled glass, the resulting products can be equal in quality to glass products made from quartz sand, the usual raw material. When plastics are recycled, however, the result is inevitably a plastic of a lower grade than the plastic from which it is derived. Moreover, no applications have been found for grades of plastic that are lower than the currently lowest commercial grade.
Which one of the following is a conclusion that can be properly drawn from the statements above?
(A) Products cannot presently be made out of plastic recycled entirely from the currently lowest commercial grade.
(B) It is impossible to make glass products from recycled glass that are equal in quality to the best glass products made from the usual raw material.
(C) Glass products made from recycled glass are less expensive than comparable products made from quartz sand.
(D) Unless recycled plastic bears some symbol revealing its origin, not even materials scientists can distinguish it from virgin plastic.
(E) The difference in quality between different grades of glass is not as great as that between different grades of plastic.

A.

No applications found for lower than lowest grade plastics = no products.

would go for A - E doesn't seem proper to me because there is no information given about any comparability between the different grades.

the argument didnt say that plastics cannot be made from the lowest quality of recycled plastic,,,but rather it said that platic products made from heavily recyled material are of no use.....

so this rejects A

in that case E is the only answer

wierd question,

Only A can be logically concluded (though "product cannot be made" is not satisfactory in A)

Sentence 2 of the passage says that when plastic is recycled the result is a lower grade plastic.
Sentence 3 says that no applications have been made from plastic that was made from recycling the lowest commercial grade plastic.

Thus, A, if you don't have any applications for recycled lowest grade commercial plastic, then you certainly aren't making products out of it.

(E) This is a very tricky answer, but the passage doesn't give us any idea as to what the variance in the grades of relative quality are.

Hope this helps

This post was
BOOKMARKED
A Because :

(A) Products cannot presently be made out of plastic recycled entirely from the currently lowest commercial grade.- Correct ( no applications have been found for grades of plastic that are lower than the currently lowest commercial grade.
) However be made vs found is something which is not too clear to relate without any if's and but's.

(E) The difference in quality between different grades of glass is not as great as that between different grades of plastic. -- hey we only discused about two grades of glass, The new glass and the recycled.Who knows there is a range of grades in new glass or even recycled glass.What author is saying is that recycled glass can be made as good new glass but not the same holds for plastic.

Hope this make some sense

weighing A agianst E ------IMO A
