"Питання і відповідь"

Questions and answer should be right, right? It is a weird sentence but it is grammatically correct.

If "питання" is "a questioun", what does "questions" look like?

And why was 'Question & answer.' marked wrong?

It seems unlikely, but could the Ukrainian "питання" and the Spanish "pregunta" be cognates? Even if they're not, this might be a way to remember the meaning.
