Question

Identifying errors

Answer 1

B it would be: " he was going to give"

Answer 2

I also concur that answer B has an error.

B: he was going to give...

So lets rewrite the whole thing. In order to prepare for the speech he was going to give to all of the parents and teachers at the school, George practiced speaking in front of a group of his friends.

After correcting B, the entire sentence flows more nicely. Hopefully this helped and good luck
