can anyone give me tips on how to write an essay on jonas salk's work on polio my professor said that i needed 2-4 subtopics.
The first step is always to gather information. Since this is not my area of expertise, I searched Google under the key words "Jonas Salk polio" to get these possible sources:
Subtopics can include personal biography, education, what brought him into the particular field, how he went about researching the vaccine, history of polio, criticisms of his work or other topics.
I hope this helps. Thanks for asking.
