Question

. Which proofreading mark would you use to indicate what needs to be changed in this sentence?
We wanted to camp at at the waterfalls.

Answer 1

To indicate the error in the sentence "We wanted to camp at at the waterfalls," you would use the proofreading mark for deletion. Specifically, you would place a line through the second "at" to indicate that it should be removed. The corrected sentence would read: "We wanted to camp at the waterfalls."
