To analyze the key idea to an essay it is best to?

A. look at the conclusion

B. Look at the focus in each paragraph.

C. underline a few key words

D. Highlight a few interesting sentences.

The answrr would most likely be A but could also be B if it isn't A

The answer would be B. I am saying this because while the conclusion would be doing the same thing, the conclusion is very broad compared to each paragraph. Looking at the focus in each paragraph allows the reader to get diverse ideas of the essay. Focusing on the different paragraphs also allows the reader to build a stronger and better summary themselves than in the actual conclusion.
