I rejected the edit because there was no straight-forward way to verify if the edited quoted text accurately represented the printed article. Therefore, either (1) the edit was improving the grammar of a quoted article, which may not reflect the original article, or (2) the edit is basically challenging the integrity of the OP by declaring the citation to be inaccurate. I chose the latter interpretation, and rejected the edit as an attempt to reply to the OP.
If the article was available to you, but you could not provide a link to the original article, you could have created an image of the paragraph in question and submitted it as part of the edit. Then, it would have been trivial to verify the edit was making the quoted text accurately reflect the printed text.
I did not choose to Skip because I did not feel that edit was acceptable as it stood without a link to the source (a screenshot would have been acceptable as well).
