I have two questions that I haven't been able to answer myself.
First of all, is it possible to use haven't alone, like in "I haven't any pets" or should it be either "I haven't got any pats" or "I don't have any pets". For me, the first sentence doesn't sound right, but some people insist on using it...
My second question is about concord of BE in sentences like "One reason for this is / are the wars." Should BE be always in concord with the subject or is it possible in cases like this to use the plural form? For some reason, are sounds better to my ear although I've been taught that in English the verb is always in concord with the subject.
Thank you very much for your help!
