Answer:
We must select the things that are part of life in Argentina.
Mate: A common drink here in Argentina.
La empanada cortado a cuchillo: This is a dish common in Argentina, different regions may have different versions of this dish, that is a small "pie" stuffed with meat cut with a knife (instead of ground beef), onions, and other things.
Yerba Mate: Is fundamental in the preparation of the mate, so this is a part of life in Argentina.
There are other options like:
Patagonia, Las pampas, Los gauchos, these are things you may see across the country, the Patagonia region and las pampas are defined regions, so not all Argentinians actually know them. On the other hand, the gauchos are common in small towns, but not as much in bigger cities.
