Spanish language Q&A Forum

As far as I can see, the text doesn’t discuss ‘hasta’ which is listed as an option in the answers but marks as wrong. My dictionary seems to have some examples where ‘hasta’ is used for movement towards a place. What is the distinction?

I was taught to use the phrase, "maquillarse la cara".  Is "maquillar su cara" natural to say in Spanish?  

I wrote "voy a maquillarle la cara", and I think this is also correct.

In the quiz asking for “half a sandwich”, I put “la mitad de un bocadillo” instead of “medio bocadillo” and was marked incorrect.  

Is my answer in fact incorrect or just not what the answer was looking for? When we say “half a sandwich” in English, my understanding is that it is really shorthand for “half (of) a sandwich” and so I thought either “la mitad de” or “medio” would be correct - perhaps that is not true in Spanish?  

Thanks in advance for your explanation.
