Read the quote.

"... the eastern Andes on one side... and the maritime cordillera on the other. Between them there
is an extensive and very lofty plateau, 13,000 to 14,000 feet above the sea, with the lake called
Titicaca... The surrounding mountains form a region of frost and snow.
The hardy llamas and
alpacas live and breed amidst the tufts of coarse grass.... Besides the grass, there is a lowly
shrub called tola, which can be used as firewood. Quinua belonging to the spinach family, can alone
be raised at the higher elevations, yielding a small grain which, by itself, is insufficient to maintain human life."

This quote describes the high-altitude plateau region of the Andes mountains, specifically mentioning the lake Titicaca and the surrounding mountains that experience frost and snow. It also mentions the animals that live in this harsh environment, such as llamas and alpacas, as well as the limited vegetation that can be found there, including coarse grass, tola shrubs, and quinua. The quote highlights the challenges of living in such a high-altitude, harsh environment with limited food sources available.
