Answer:
<u>Elion learned everything she needed to know from her courses.</u>
Explanation:
"Unable to obtain a graduate research position because she was a woman, she took a series of jobs, including lab assistant, chemistry and physics teacher in New York City high schools, and research chemist."
If you remove that, you don't learn that she learned not from her courses, but from her real life experiences. So egro, you believe she learned everything from her courses.
