"今天我等了他们一个小时。"

Translation: I waited for them for an hour today.

"Today I waited for them for one hour" or "I waited for them for one hour today" should also be acceptable.

Like I've already said elsewhere, there are a LOT of mistakes in the answer bank for this particular module. You good people will probably want to give priority to fixing this one first.

@English speakers, it should be 'a hour' right?

[Celticfiddleguy]

No, its "an hour". This is because the "h" is silent so when spoken "hour" begins with a vowel sound.

"I waited an hour for them today" should also be accepted.

[MilanLin]

You used the wrong word.
I waited for them for an hour today

What's wrong with "I waited for them an hour today"

[AlejandraV14298]

"Have" should be added to the word bank. "Today" is an unfinished period of time...
