The current "solution" of "she reads faster than me" is incorrect English.
We're describing an action, not a noun, so we need an adverbial construction in the English (more quickly), not an adjective (faster, quicker).
Presently, the actual correct answer is not yet accepted. It needs adding, and ideally, the incorrect answer removing from the database.
Additionally, since we're describing an action that's more active than merely "being", English strictly speaking requires "...than I", not "...than me" in this context (exactly the same as the Russian) - although probably best to accept both, as "...than me" is in very common usage despite being grammatically questionable at best.
Well, it's certainly widely used as such in the US, not so much here (UK). Makes sense that it has made its way into even our dictionaries by now, something that had hitherto escaped my notice.
That said, the other forms (such as "more quickly") still need adding, of course, or else a lot of British learners of Russian are going to be quite frustrated trying to remember the preferred modern/American way of saying things.
"[...] a lot of British learners of Russian are going to be quite frustrated trying to remember the preferred modern/American way of saying things."
Simply look at it as an opportunity to learn two languages at the same time!
I mean, you're already learning 16, what's one more?
I am from the UK and I would say that faster is fine, I have always used it as such.
Also there are arguments that 'than' can act as a preposition as well as a conjunction, making 'than me' also correct. Given that this is not really a closed case I don't think English 'strictly' requires 'than I'.
When you started typing a post for this thread the site specifically asks you to report mistakes and not post them here. The reasoning is that it will be confusing for other learners if there are posts about "mistakes" here that differ from what the official course creators decide are correct. Even more confusing is when the supposed mistake is actually correct, which is the case with your complaint.
Well, I think this thread proves exactly how wrong you are. I don't know how long ago this comment was posted (damn android app), but I'm guessing some time ago... and the mistake (which IS clearly a mistake, I'm not sure why you have said it is correct when it isn't) is still here – it hasn't been fixed. So, for people who have their doubt about the sentence are able to refer to the commenta and see exactly what the situation is. This is EXACTLY what the comment section is for.
