HELP MGertrude Belle Elion was born on Jan. 23, 1918, in New York City. She graduated from Hunter College in New York City with a degree 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

Chronologically

Explanation:

Chronologically - putting events in order from when they occurred.

The author puts events in chronological order.

When an article is organized chronologically you can almost create a timeline with the events:

Gertrude Belle Elion  was born on Jan. 23. 1918.

She graduated with a degree in biochemistry in 1937

She earned a master's degree in 1941.

Reasons it can't be the other answer choices.

Interviews and research - if the author organized this article using interviews and research there would likely be sourcing of the research and interviews. There is no sourcing so the author could not have used interviews and research.

Cause and effect - Although there is one cause and effect situation present in this article, the author did not organize the whole article using cause and effect situations so the author likely did not organize information in this article using cause and effect.

Problem-solution - when an author uses problem - solution to organize their article the article usually ends in the a solution to the problem. Although there was some type of problem ( Gertrude not being able to obtain a graduate research position, nor her doctorates ), the article did not end in the problem being solved. So the author likely did not use problem - solution
