In learning the Big "S" in "Sie" means you formal and "Ihr" you formal. Duolingo needs to example a better explanion of the contexts of the usages of "Sie" or "sie" or "ihr". When I see "Sie lesen Zeitungen", I will all ways pick the "Sie" you are reading the newspapers" because this sentence has no understanding of the useages of The "Sie" you usages. or "Sie" they. So please, duolingo, explain why this sentences is with the "Thy" over the "Sie" you. I have read your explainion on this mater, and as you can see, it is not helping me to get this or any other sentences like this contexts right. Richard.
Sie lesen Zeitungen can mean "You are reading newspapers".
It's an error that that correct translation is not accepted.
But this sentence was added by the Pearson team. It's not part of the public course.
Unfortunately, at least some sentences that they created for their course have leaked into the course that the public sees, leading to inconsistencies in what is taught, how, and in what order.
This should be sorted out eventually but right now it's a bit of a mess.
