"You are reading a book."

Translation: Tu lis un livre.

[stefants92]

How was I supposed to know that "Vous lisez un livre." was a valid answer at this state?

[bngmaildotcom]

yes, we haven't seen many "vous" sentences.

[a.french91]

Why is vous lisez also not a correct translation?

[RyanPi]

It should be now at least. I answered the question with the "Mark all that are correct" with both tu and vous forms and got it right.

[yachin]

there are two answer?

[GirsBilingual]

vous lisez un livre is also a valid answer; unless you were saying "There are two answers, why isn't the other one listed" in which case, Yes. Why, in fact?

[Jamovic]

Tu lis isn't correct?

[luckypierre]

Surely it IS correct!

[Danice]

I marked both tu and vous and got it WRONG! I note that below someone did that and was correct. I was corrected and told only vous is the correct answer. So now I am confused? Help please.

[skersh]

I thought if using "ing" you use être conj. and then the verb+ant? Ex: I eat is je mange but I am eating is je suis mangeant?
