"Today I waited for them for one hour" or "I waited for them for one hour today" should also be acceptable.
Came here to say that.
"Today I waited an hour for them" should also be accepted
I wrote exactly that, and it was rejected!
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.
Today I waited one hour for them
i can't hear 了
@English speakers, it should be 'a hour' right?
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.
You used the wrong word.
I waited for them for an hour today
What's wrong with "I waited for them an hour today"
"Have" should be added to the word bank. "Today" is an unfinished period of time...
