Above the tree line there is a zone that is generally called alpine tundra. Immediately adjacent to the timberline, the tundra consists of a fairly complete cover of low-lying shrubs, herbs, and grasses, while higher up the number and diversity of species decrease until there is much bare ground with occasional mosses and lichens and some prostrate cushion plants. Some plants can even survive in favorable microhabitats above the snow line. The highest plants in the world occur at around 6,100 meters on Makalu in the Himalayas. At this great height, rocks, warmed by the sun, melt small snowdrifts.
"This explains how, for example, alpine cushion plants have been found growing at an altitude of 6,180 meters."
C와 D중에 고민하다가 문장의 for example 때문에 C를 골랐는데 틀렸네요.. 정답이 D인데 This explains가 바로 앞문장 At this ~ snowdrifts를 받는것 같기도한데 for example이 들어간 문장이 문단 가장 마지막에 올 수도 있는건가요?
for example은 보통 문단의 3/5이나 4/5 지점에 위치하는걸로 알고 있는데 좀 어렵네요
도움 부탁드립니당!!
