Thanks for pointing that out, Priya.

I've noticed that sentences 8 and 10 in this test also have typos:

8. neighbor's --> neighbors'
10. abilitly --> ability
.

Would someone explain this sentence to me, please?

Hi Mickey,
"knock on" is a Rugby term, it means "knocking the ball forward while trying to catch it". The knock on is a foul in the game.
Certainly, that's rather late for an answer :) But perhaps, that would be of service to someone else.
