So what are the differences we can see between these two lines?
Your code has extra double quotes which were not there to begin with.
The original sentence had a period at the end, but it has disappeared in your version.
The hyperlink in your version is the blue text ‘cat photos’ after the given sentence, while the hyperlink in the requested version is part of the given sentence.
Solutions?
I feel that for #1. and #2, you can probably fix these without help.
As for #3, you must move the starting tag of the anchor tag and place it carefully to the left of the word cat in the original paragraph (you may want to reset the step first)
Then move the closing tag for the anchor to the right of the word photos (but to the left of the period)
Hopefully if you do this carefully enough, you get a working result.
