Question

Though it experiences freezing temperatures, much of Antarctica is considered a desert because it shares a key quality in common with other deserts: like all deserts, it has __________.
a. flora and fauna in common with the Sahara
b. extreme temperatures that make settlement difficult
c. large ice caps and ice sheets
d. an average of less than 10 inches of precipitation per year

Answer 1

Antarctica would have flora and fauna very different from Sahara - so we can exclude this option. Also, Sahara doesn't have ice sheets - so we can exclude option c too.

The correct answer is d- deserts are usually defined in their relatively low level of precipitation.
