I had to read this modification three times before I finally understood it:
"On page 9, second full paragraph, change the following last full sentence that
appears on that page: 'The tow truck driver give his father a receipt' to 'The tow truck driver gave his
father a receipt.'"
I thought: Wait. Did the original say that the tow truck driver gave the driver a receipt, when really it was the father who got it? Or did the original erroneously talk about the tow truck driver's father? I kept staring at the modification trying to figure it out. 'Cause usually these types of modifications entail edits where the original opinion erroneously refers to the wrong person doing X or Y.
Only on my third reading did I finally get it. It wasn't a substantive error. It was just a typo. "Give" versus "gave". Something not caught by a spellchecker.
But yeah. Gave. That's right.
Grammar.
