Q32: It can be inferred from the passage that refraction would be most likely to cause errors in measurements of a mountain’s elevation under which of the following conditions?
A. When there are local variations in sea level
B. When light passes through humid air
C. When theodolites are used relatively far from the mountain peak.
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.
选D?文中的句子只说了The Chinese also launched weather balloons near their theodolites to measure atmospheric temperature and pressure changes to better estimate refraction errors.我怎么看不出来隐含的那个low air temperature and pressure呢？劳烦啦，谢谢！
