Choice C is correct

To reduce refraction errors, the

Chinese team carried in sea level to

(35) within five to twelve miles of Everest’s

    summit, decreasing the amount of air

that light passed through on its way to

their theodolites

We can know that: decrease the distance-->reduce refraction error

So we can infer that: increase in the distance-->increase refraction error (refraction would be most likely to cause

errors)
