I agree with you on all except #3.
#15 is weird. I'd put a comma after business and before the single quotation mark ... but the other 3 are incorrect, too.
In #17, I hope the book's title is in italics in your original!
In #20, I hope that comma before your arrow was a typo!!
Maya has made errors.
#3, the answer is the third because there has to be a comma after Alan.
#15, I'm really not sure about it either. It does look weird, but the first choice is the closest.
#17, The book is in italic
#20, the coma was a mistake i did.
Thank you soo much for helping me.
