Plz tell 3 things wrong with this summery. Student J. Doe's Summary

Gertrude Elion was born in 1918 in New York City. She went to school for many years and eventually won the Nobel prize. She was 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. She was a scientist who helped discover many important drugs that saved lives. Elion also discovered new ways to test drugs. She died in 1999, 16 years after she retired from Burroughs Wellcome Laboratories. I think she was a terrific scientist.
