Sorry, it was not clear.
These kinds of books have grown into a major market, accounting for 25 percent...
Subject(S):these kinds of books
have -ed: have grown into a major market
,-ing: ,accounting for 25 percent...
Here 'S have -ed, -ing' is not 'S have -ed, and have -ed': it is not 'These kinds of books have grown into a major market, and have accounted for 25 percent...'
I've been wondering if there is some cases where 'S have -ed, -ing' IS 'S have -ed, and have -ed.'
Would you come up with any, Jim?
