# Which of the following, if true, most strengthens

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

### 2 Explanations

1

(A) is irrelevant. Whether the bottle can be crushed does not, as far as we know, affect how much plastic waste is produced.
(B) is the best choice. If the partially biodegradable bottles contain more plastic, and the plastic itself is not biodegradable, then these bottles actually produce more plastic refuse per container than the non-biodegradable bottles
(C) Whether or not consumers prefer to buy the partially biodegradable bottle has no effect on how much plastic is produced
(D) is out of scope. We're concerned with the waste produced when the bottle is discarded, not when it is produced
(E) has no effect on the argument since it applies equally to both types of bottles
