The correct answers are:
1) The Andes Mountains;
The tectonic activity between the Nazca plate and the South American plate have created the longest, highest, and by far most dominant mountain range in the South American continent. As the two plates were pressing against each other, the pressure started to lift the surrounding land, and as the time was passing, the land was becoming higher and higher until it became an very long linear shaped, north-south stretching, mountain range, the Andes.
2) A parka;
Tierra del Fuego is a place where the weather conditions are very harsh. It is very cold, and the winds are pretty strong for most of the year. So an item like the parka will be ideal for the visitors of this part of the world, as the parka is an item that can provide very good isolation from the cold temperatures and strong winds.
