Oh, I see Mr. Micawber. Some can use both a plural and a singular noun. That sentence refer to a singular noun.

Thanks.

[Mister Micawber]

No, I am just telling you that, singular or plural, it is the wrong answer to the question.

'Some' cannot refer to a singular noun in that structure, though it can refer to a portion of a singular noun like this: 'Give me some of your hotdog'.
