Chem question help pls

Hi, please could I have some help on this question?
Which statements are correct in terms of the Brønsted-Lowry theory of acids and bases?
• Water can act as either an acid or a base.
• Sulfuric acid, H2SO4, does not behave as an acid when dissolved in ethanol, C2H5OH.
• The ammonium ion acts as a base when dissolved in liquid ammonia
I’m confused about statement 2, I’m not sure whether the proton will go if sulfuric acid does behave as an acid? Also I’m not sure about the third statement, how is the ammonium ion going to accept another proton?
Thanks!

Statements 2 and 3 are both false. Ethanol can still pick up protons (the hydroxyl group has available lone pairs on it), so H2SO4 can still act as a proton donor in it. 3 is false for the reason you have stated - it can’t pick up another proton
