Quiz question Le bureau de poste est ouvert aujourd'hui ________ onze heures.

Hi Ben,

... de dix à onze heures -- from 10 to 11 o'clock.
... de dix heures à onze heures -- from 10 o'clock to 11 o'clock.

It's just as correct but wordier.

It seems just as correct, but it was ruled incorrect when I answered as such (de dix heures à onze heures). It only accepted  "de dix à onze heures" as the correct answer.

Is it equally correct to write de deux à deux heures et demie? I was marked wrong for not writing de deux heures. Looks like Chris says either one is OK so I need to If he’s right. Thanks!
