I don't find any reading material, or Tips & Notes. I searched the whole app, but there is nothing at all. All I have is this comment section that shows after each question. But I can't go back to it if I skipped it. I have to wait until the same question shows up again.
tips notes, as well reading material, you can find when you scroll down the page of every practice (I do not know about other, but that shows up only when I'm on the computer, and never when I'm on my cell phone).
you can get to the discuss section of every sentence if you'll write the original sentence at the search bar that appears when you click on the Discussion button, next to the duolingo logo, again, for me is shows up only when I ' m on the computer (just to clarify, when I wrote "original sentence" I meant the sentence you were asked to translate, for example, this discussion "original sentence" is "זה שלה").
the only big problem I have with the app is that I can't comment when I'm using it from the cell phone (I can get to the discussion section, but after clicking the post button I get a message that a problem occurred and my response was not published
@airelibre (I hope this tagging will help.. )
If you want the whole course tips and notes in one PDF it's https://www.docdroid.net/JnfmyEV/tipsnotesbackup.pdf
At the beginning of each lesson, under the different test activities, there is reading material. It is also accessible during the activity by pressing "Tips & Notes" in the top left of the screen.
Now, to answer your question... זה לה translates literally to this is her. I'm not 100% sure whether it would work as an answer to 'Can you point out who gave you that delicious muffin?', but I would assume it does.
