Passage

Brand A's headphones cost less than Brand B's headphones. Therefore, Brand A's headphones are the better choice.

Question

What additional fact would most strengthen the conclusion?

Answer

Independent tests rate Brand A's sound quality and durability equal to Brand B's.

Solution

1. Price alone does not establish overall value because quality may differ.
2. Equal sound quality and durability remove that concern.
3. The lower price then provides strong support for choosing Brand A.
