Response to a reviewer for a duplicated paragraph I had a mistake in my paper and I had a duplicated paragraph in my paper. Now, reviewer told me that it is duplicated and ask me for a description for the problem.

I have deleted the paragraph but I don't know what to say in the response letter about the comment?

May you please tell me that what is a good sense response to tell to the reviewer about the paragraph. I think that it is not good to say that it was just a mistake.

Thank you
Say that it was a mistake and the extra paragraph was removed in the revised version.

I can not see the need for going further in this issue. You should be pragmatic, I bet that there are several important points to address in your revision and this is not one of them.
