Gertrude Belle Elion was born on Jan. 23, 1918, in New York City. She graduated from Hunter College in New York City with a degr
ee in biochemistry in 1937. 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. During this time she also took classes at New York University, where she earned a master's degree in 1941. Because she could not devote herself to full-time studies, Elion never received a doctorate. How does the author organize information in this article to create a clear main idea? Chronologically Interviews and research Cause and effect Problem-solution
The best answer here is chronologically. If we read the excerpt, we can see that the author is starting at the beginning and following a timeline to describe each thing about Gertrude Belle Elion. The other options don't make much sense because there are no interviews cited, though there was obviously come research done. Cause and effect doesn't make sense because there isn't any sort of indication of the causes and effects of certain things except at the end when we find out she never earned her doctorate. The same holds true for problem-solution.
