Why can't we say "N'importe que se passe" to say "Whatever happens"

I was surprised to see my use of "cet après-midi" corrected to "cette après-midi". So I looked it up and found that both genders are used for that phrase.

I selected nationality with Capital letter, but it says I selected lower case

Hello,

I was wondering, for this question:

why the answer is vieil and not vieux, like from the list on adjectives that go before nouns?

Martin likes Sarah. -> Martin aime bien Sarah. I answered this question with simply "Martin aime Sarah", and I wonder why was it marked as a mistake. Nothing in the question suggested that it's the friendly sort of like, it could very well be a romantic sort of like. Both options seem grammatically correct to me. Isn't that right?

Why is it 'on en achètera une fois qu'on sera arrivés" and Not 'on en achètera une fois qu'on arrivera"
