Thanks! It's really difficult to grasp all these rules, your help is very much appreciated.
If only the app allowed people to comment on each exercise in order to get an answer.
o'clock is one word. It is not written as o' clock with a space like that.
I had the same on a word selection exercise where i was forced to select o' and clock as separate words.
Duo seems to have an issue with the word order, I've flagged it.
Yes, it fails on "It is now two o'clock" too. Flagged to allow the word order since it's pretty common.
We don't know if it is 2 PM (1400) in this sentence or not, it could very well be 2 AM.
Could два часа mean both two o'clock and two hours? How to distinguish the two meanings in Russian?
I hopefully don't sound rude but could you provide examples in English and we can post translations ? That might be easier.
