I've had a friend similar to yours, yeah you can encourage them to eat but don't make them feel to bad about it. Just try to be there for them because there might be a reason behind why she isn't eating, you should maybe ask her about it. If it gets really serious you should go to an adult.
I hope everything gets better : )
The answer is C, body language. Body language is very important in communication. If you are in an interview and you're fidgeting...looking around the room...pacing....slouching....chances are you aren't going to get the job.
Where's the tile? So that I can help you out with that
