Do you use лет or года when you have "(a number that takes лет) или (a number that takes года) (years old)"?
- «Год» is used with numerals ending in 1 (but not 11).
- «Го́да» is used with the numerals ending in 2, 3, 4 (but not in 12, 13, 14).
- «Лет» is used with all the other numerals.
I think the question is if you've got two numbers which would use different forms, e.g. "11 or 22", then which would you use?
Oh! I would normally repeat the noun:
- Оди́надцать лет или два́дцать два го́да?
But if the noun is not repeated, you use the form of the closest numeral:
- Оди́надцать или два́дцать два го́да?
- Оди́надцать лет или два́дцать два?
You need an "or" between eleven and twelve. I also think saying "either ... or ..." is a bit closer to Russian "или ... или ...". and probably wouldn't be accepted as an answer here anyway.
This sentence is odd. And what is the difference in spoken language? I still can't recognize the accent of a statement from a question.
You won't get it from the TTS here, it doesn't do questions very well. For purposes of this course it's a question if it has a question mark at the end; on the dictation exercises punctuation isn't graded.
In normal speech with humans the question intonation is a bit different from English, I think. I don't recall having a problem with understanding it though.
