D、When weather balloons indicate low air temperature and pressure.
E、When sea level has been carried in to Within five to twelve miles of the summit.
答案:
C
提问：
请问一下张慧雯老师:) 我先看到题目中的refraction would be cause error 然后定位到第二段的第二句：One source of error is refraction, the bending of light beams as they pass through air layers of different temperature and pressure. 这句话跟B选项相关（想问下怎么选到C？）
