The correct answers are:

1. D. the Andes Mountains

- The collision between the South American tectonic plate and the Nazca tectonic plate has caused the formation of the Andes Mountains. Because the two tectonic plates in question have the same densities, they push towards each other and from the pressure that's created the ground had started lifting and over time created the most famous mountains of the South American continent.

2. C. a parka

- Even though the name Tierra del Fuego (land of fire) suggest that this is a hot place, it is actually the total opposite. Tierra del Fuego is on the Southernmost part of the South American continent and it is a place that is very cold and has strong chilling winds for most of the year, so a big thick warm coat like the parka is a must to have item to keep you warm and not let hypothermia do its thing and cause damage or even death.
