I was taking an English test and I haven't know which sentence is wrong. could you help me out?
a) The telephone is ringing. I will go to answer it.
b) I feel like going dancing tonight. Would you like to join me?
I don't know if in letter "a" I should say: ...I will go answer it, rather than I will go to answer it; or
In letter "b": I feel like going to dance, rather than I feel like going dancing tonight.
