Question

Which issue should be corrected prior to the proofreading stage?

Answer 1

The spelling errors could be corrected. This describes the defination of proofreading. It means reading ur text over and fixing the spelling errors.

Answer 2

I've always been told check for spelling errors first, which technically you are beginning the process of proofreading.

Next, I've been told to look for usage errors, which means, did you use the word in the correct context.

Then I believe you look for grammar mistakes, which includes subject verb agreements, fragments, punctuation, and can include style of the paper, which I believe looks at the sentence variety.

Hopefully this helped and good luck.
