Thank you all very much.
I apologize for the confusion. But I am not as guilty as I may seem.
When I first posted my question, there was only one sentence in it. I added the second one after a couple of minutes. Then, a very short time after posting, I say your reply. It read 'It's ambiguous'. I thought that you had seen my original post and not the edited version. I thought you had posted while I was editing my first post. The original post contained only one sentence. The edited one contained two. The problem was that you had written 'it' and not 'they'. Now I realize it was probably a slip; a slip that in other circumstances I would not have paid any attention to. But here, it became significant in that it was implying that there is only one sentence that was ambiguous. So I edited my post again. The post was edited twice. The last version was the same as the first one. Both contained one sentence. The second version, which is the one you saw, contained two.
I hope this is comprehensible.
My apologies again.
Navi.
