有什么事是我该做的吗？ Is there anything I should do?
I realize this is a strange sentence, per the discussion in this question about the same sentence. However I want some clarifications about the existing sentence:
1) Per AllSet Learning, 是 should connect two nouns. Here it connects "什么事 / anything" to "我该做的 / 'I should do' descriptor". Is it correct that descriptor clauses with 的 are nouns?
2) Is 什么事 a single term that corresponds to "something/anything"? What's the difference if I drop the 事?
