The translation is: I am going to a concert tonight. What time? (or what i think it is)
for this answer just put down a time like: a las ocho de la noche
hope this helped! (:
talk of what i do not get it
Mi abuelo es argentina is incorrect because abuelo means grandfather, who is obviously a male, and the adjective argentina is used to denote feminine gender because it ends with -a. Instead, if you want to correct this sentence, you should write the adjective in masculine form (ending with -o).
So, it should go like this:
Mi abuelo es argentino.
