"Кто хочет ответить на этот вопрос?"

Translation: Who wants to answer this question?

[raskolnikov88]

"Who wants to answer that question" seems just as appropriate but was inexplicably rejected

[jaiirapetjan]

That's what I wrote. I'll report it and see if they will accept it in the future.

[Oinophilos]

that question should also be allowed

[Haggra]

If someone else also gets curious, ответить is the perfective form of отвечать.

[CJlon]

Why is there a "на" and what's the case after it (seems nominative?)?

[2E3S]

You have to remember some constructions, like here: ответить на что-то=answer something, respond to something, e.g. ответить/ответ на вопрос, ответить на провокацию.

[yarjka]

на + accusative

[BenYoung84]

You will never see a nominative form after a preposition.

why "who wants to reply this question" is wrong?

[TheRunawayFound]

In English we reply to questions.

[Marierinc]

Why "who wants to answer to this question is wrong?"

[JANBOEVINK]

Hi Marierinc, as TheRunaway said: -reply to- or -answer- are the two options here.

[Bruno241677]

I said the same and it says wrong... weird

[Peter435682]

Why the imperfective ответить rather than perfectice отвечать? Does it have something to do with the compound verb construction here, [conjugated verb]+[infinitive]?

[Adrian53542]

ответить is the perfect and отвечать the imperfect.

I haven't mastered aspects yet, but I think it has something to do with answering a question being a singular action, which thus requires the perfect.

''Rather than referring to ongoing actions or past(future) actions in general, perfective verbs refer to actions in a point-wise manner, ignoring the action's inner structure. That is, such "singular" actions happen at some particular "moment" and can be conveniently arranged in a sequence when telling a story. ''
