"They are both in the room."
Translation:Onların ikisi de odada.
I was VERY astonished to find that half of the words I was supposed to have learnt I hadn't come across in the lesson. So I did the lesson over and lo' and behold: same phenomenon. First time I have had this problem. In the lesson, neither "hem" nor "ikisi", they only crop up in "strengthen". And since there seem to be no "notes and tips", my question is: how am I supposed to learn them? Is something wrong with this lesson?
