Which climate zone has cool summers, cold and harsh winters, a dry climate, and sparse vegetation

The correct answer is the following: The climate zone that has cool summers, cold and harsh winters, a dry climate and  sparse vegetation is the Tundra. Tundra's are among Earth's harshest biomes, with ecosystems with treeless regions, with cold and harsh winters, and where rainfall does not come often. This dry climate makes the existence of vegetation sparse, until cool summers comes and brings some wildflowers.

role is closest to part because when replacing words, "playing a vital decision," "playing a vital activity," and "playing a vital dollar" don't make logical sense. the only meaningful choice is "playing a vital part."

this fits one of merriam-webster's definitions of role: "a function or part performed especially in a particular operation or process."
