"Do you know a lot?"
Translation:Вы много знаете?
Thanks, Oleg6692. This helps. The problem is that the exercise can't make it clear, but this tip about which word matters more helps.
And never say you're sorry for your English. Going out of your way to learn a language - and help others through it - excuses whatever blemish you may think your use if the language has :)
The word order doesn't matter. At least both must be accepted for that English sentence. It is again a Duo mistake. (there are many in this Russian course, mostly stresses are on wrong syllables, and questioning sounds as they were statements. And now Duo made a word order mistake.
