14/14 as I knew what answer they were wanting for things, but I don't agree with some of them, and I think it's a dreadful test for actually testing grammar and punctuation.
Several things described as 'sentences' have no full stops.
I think it's arguable as to whether 'team' is abstract or concrete. You might be able to see a team, but I think it's the players that you see; the concept 'team' is abstract to me. I can see how someone would argue the other way though.
'to the foot of the stairs' is surely two prepositional phrases, not one.
I am not convinced that 'He thought he might...' is a conditional sentence. If it had said 'He might...' then yes. But adding 'He thought...' beforehand surely makes it grammatically past tense, even if it happens to express a conditional idea.
And I think several of the questions are not really testing what they purport to test. A multiple choice test concentrating on grammatical terms doesn't seem to be effective in my mind, although I agree that some degree of terminology is needed.
