Critical Reading Q

<p>Hello,
For The Official SAT Study Guide Second Edition Practice Test 9 Section 6 #12, I do not understand why the answer is D rather than A. I chose A because the use of chemistry metaphor can be inferred from the rest of the passage to characterize the challenges of Black Women described in subsequent paragraphs.</p>

<p>I do not understand the Collegeboard explanation of why the chemistry metaphor suggest "the way certain influences interact to produce a unique perspective." What from the passage suggests this and how do you know?</p>

<p>Thanks.</p>
