Entender means understand, but in this example: Ella entiende de arte. - means: She knows about art. Why?

Thank you so much!

I understand the line ' .. para realizar el sueno de crear una marca de aceite oliva referente en calidad y sabor' to mean '  in order to realize the dream of making a brand of olive oil that is a benchmark in quality and flavour. 

Why is there no other connection words between oliva and referente? 

Thanks!

I am curious how this structure would work if the direct object is a pronoun, something like the following.

I had a beautiful beer mug.  I accidentally dropped it.

The lesson doesn't seem to differentiate between these two words and the 2 quiz questions just require the same single word answer.  Is there anywhere that explains the differences in more detail please?

My question and answer: How would you say "For many years I have done Tai Chí"?  I picked "Desde hace muchos años hago Taichí.  But it says the correct answer is Desde much años hago Taichí.  

Looking at the lesson that the link takes me too, I only see to use Desde when the time is specific like 1 year.  

Please help.

I am finding the use of the verb Hay in tenses other Present Indicative confusing. Is it because the verb retains its multi purpose use of meaning? I mean, "hay" means both "there is" and "there are" in the Present Indicative, and "hubo" means "there was" and "there were", even though the following noun is plural? Also, after "si" when is "hubo" used in preference to "hubiera"?
