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）

(E) She fails to show how mere support for human values actually preserves human lives.

第一次做的时候选B半个月后一看又选了A，觉得B指出的不是逻辑错误而是道德观念上的不好吧，不知对否；而A得错就不太想的清了，还请明白人给说两句啊~不胜感激！

To answer this question, we need to identify that the flaw occurs at Susan's 2nd paragraph. Her main argument point for the whole is the 1st sentence in her first paragraph. "Those who oppose experimentation on animals do not properly value the preservation of human life." Choice A is only just repeating her words. The underlying meaning is choice E. Therefore, E is the best answer.
