The answer that I put down on my test is Stem-changing -ir describe how you are feeling in the future and -ar & -er describe how you are feeling in the present. And it all depends on the words around it if it should end in er then the word would end with er feminine masculine. a or o e or i.
Hope this helps

It can be the A because they are imperative, but they are very formal.
