How should you explain your supporting evidence?
without topic sentences
in at least 500 words
as clearly as possible
briefly and without detail
C because you don't want it too long, you want to stay on topic, and you want to give enough detail to have the reader understand your thought process.
The supporting evidence is the supplementary document which is supplied so as to verify the finding of one person or persons. In this case, supporting evidence must be as clear as possible. Details should be provided here since it is the supplementary one. There is no limit of words and the topic sentences should be present.
