### 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.

I got E by POE...whats wrong with it.

The statements says that glass can be recycled forever while plastic, once it reaches its lowest grade, becomes trash.

OR
Glass maintains its quality.

A.

(A) Products cannot presently be made out of plastic recycled entirely from the currently lowest commercial grade.
- Yes, "no applications have been found for grades of plastic that are lower than the currently lowest commercial grade" says it.

(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.
- It is possible, as the passage suggests.

(C) Glass products made from recycled glass are less expensive than comparable products made from quartz sand.
- price is irrelevant

(D) Unless recycled plastic bears some symbol revealing its origin, not even materials scientists can distinguish it from virgin plastic.
- it is distinguishable...recycled plastics are lower grade.

(E) The difference in quality between different grades of glass is not as great as that between different grades of plastic.
- this is too extreme on the glass end. although recycled glass CAN be equal in quality to new glass, the passage doesn't say that it is ALWAYS equal. thus u can get really poor quality recycled glass. For example, once recylcled plastic has quality rating of 9/10, a glass that is recycled 20 times can have a quality rating of 4/10. In this case, difference in quality between diff grades is greater for glass than is for plastic.

A is a sure thing, E is going a bit too far.

Thanks ricokevin...I got a little carried away by the change in words from "No application" to "No Products" and cancelled it out.

I was also confused between A & E.

But the question stem mentions nothing about different grades of glasses. So E is out and the answer is A.

A is correct. E is incorrect because no relative information is presented from the argument.

How can A be correct?

The stem says:

no applications have been found for grades of plastic that are lower than the currently lowest commercial grade

LOWER then the currently lowest commercial grade

A states:
(A) Products cannot presently be made out of plastic recycled entirely from the currently lowest commercial grade.

so this says it cannot be made at the currently lowest commercial grade but the stem says applications cant be made for grades of plastic lower than the lowest commercial grade

can someone explain my error in logic here?

Straight A.

The key here that links A to the question is :

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.
