Answer 1

A) There is no coffee! I am going to get some.
B) My birthday will be next month.
C) I am going to invite her friends.

ps: eu não tenho certeza, mas uma dica que eu posso te dar é que o will se refere a um futuro incerto e o going to se refere a algo que vai acontecer (de certeza). Espero ter ajudado :)
