Let S denote a singular noun and P a plural. Then in an interrogative, how do you determine the verb's grammatical number? I recollect that I read a claim, possibly on ELU, that in a declarative sentence, the verb's grammatical number is simply that of the closest noun.
Are the foregoing claim and the following examples right?
1. Is /Are there any S or P?
2. Are /is there any P or S?
