I might have asked before but could this not be questions? Maybe it is an interview.
'Question' as a verb is more like fråga ut (particle verb, stress ut; means 'ask a lot of questions'), förhöra (= 'interrogate') or ifrågasätta ('cast doubt on').
I am confused here :( Why is "Flickan frågor och kvinnan svarar." not correct ? Isn't ask = fråga and frågor in plural ?
Verbs don't have singular or plural.
If you mean that the verb should be conjugated as frågor when the pronoun is plural: no, verb don't conjugate in Swedish. The present tense form is used in the present tense (simple and continuous) with all pronouns equally
I think they may have confused the POS - the noun "question" is fråga in the singular and frågor in the plural. Obviously, what you say is correct.
