"Proč zvolili tohohle člověka?"

Translation: Why did they elect this person?

[Praha2017]

Could you please explain the difference between 'to elect' and 'to vote for'?!
In this exercise sentence the proposed answer for "Proč zvolili tohohle člověka?" is "Why did they elect this person?"

My sentence before was "Koho jsi volil?" and my answer "Who did you elect" wasn't accepted, it should have been "Who did you vote for". Is it the volit - zvolit difference?

[VladaFu]

volit - to vote for, to give the person your vote

zvolit - to elect, to put the person in the position they were running for
