"Ella ha roto con él pero ________ así él sigue insistiendo.

She broke up with him but even so he keeps trying.

(HINT: aún or aun?)" 

I've already forgotten which I picked, but I got it wrong. My confusion is that according to the lesson, both "aun así" and "aún así" mean "despite that". I can't think of a sentence in English where "even so" is not interchangeable with "despite that". It certainly seems like they are interchangeable in the quiz question above. Is there a nuance that I'm not grasping that explains why only one of the options is correct? 

I put argentina nacional instead of nacional argentina. Can't the adjective go after the noun here or does it have to be before it? Thanks.

Using the example from above:

Tenía que conseguir cualquier trabajo, ya fuera de día o de noche.

I had to get a job, either a day job or a night job.

1) can it be used with MORE than 2 choices?

ex: "I had to get a job, either a day job, a night job, or a part-time job."

and

2) Not sure how ask gramatically... could it also be used in just 1 phrase?ex: "I had to get either a day job or a night job."

Thanks
