Susan: Those who oppose experimentation on animals do not properly value the preservation of human life. Although animal suffering is unfortunate, it is justifiable if it can lead to cures for human ailments.
Melvin: But much animal experimentation involves testing of ordinary consumer products such as soaps, dyes, and cosmetics.
Susan: These experiments are justifiable on the same grounds, since cleanliness, convenience, and beauty are worthwhile human values deserving of support.
Which of the following is the best statement of the logical flaw in Susan’s argument?
(A) Her claim that animal experimentation is justifiable if it supports human values contradicts her claim that such experimentation is justifiable only if it leads to cures for human ailments.
(B) She places a higher value on human cleanliness, convenience, and beauty than she does on the preservation of animal life.
(C) She uses the word “value” in two different senses.
(D) She assumes that all ordinary consumer products aid in the preservation of human life
(E) She fails to show how mere support for human values actually preserves human lives.

答案是E ，为什么不是C？

C的话value只是一个动词一个名词，算不上是logical flaw吧
E的话说她么有讲人的价值是保命
