A question regarding noun clause/substantive clauses.

[TarunK667]

Recently I came across a source that said that following two sentences are correct:

What concerns me is election results.
What concern me are election results.

Are both of these sentences correct? As far as I know, noun clauses "what concerns me" or what concern me" are singular subjects so should take singular verbs, but above mentioned sentences also looks correct to me. Can you please help?

Regards

Recently I came across a source that said...

please respect the forum rules. you can't do this ^^ ... you need to IDENTIFY the source.

[RonPurewal]

the first sentence is legitimate; the second one isn't.
the only official problem that has ever tested anything of this sort is this problem:

if you have a source that seems to differ, then you need to post a new thread EXPLICITLY IDENTIFYING the source, and also reproducing the COMPLETE problem, exactly as originally provided (including all answer choices, if answer choices were originally provided).
thanks.
