I know it's useless to disagree with Official answers and all that, but please allow me,

Q32.

The official answer is D, but it says "When weather balloons indicate low air temperature and pressure." so, same level of temp and pressure.

according to the text,

"One source of error is refraction, the bending of light beams as they pass through air layers of different temperature and pressure. " so the refraction is the result of passing through DIFFERENT T and P, Therefore D just can't be correct here. ~

Am I missing something?


Hi, I would like to add my 2 cents on your concern. As per my understanding, (D) is not wrong, or if any, not wrong for the reason you cited.

First of all, in the passage: "One source of error is refraction, the bending of light beams as they pass through air layers of different temperature and pressure. ---> It is mentioned that temperature and pressure of one layer is different from those of another layer.

In option D: "When weather balloons indicate low air temperature and pressure." --->In my initial reading, I thought this sentence meant that there is a difference in air temperature and pressure of different layers. In more details, temperate and pressure of one layer is lower than those of another layer. That's why there is no inconsistence between option (D) and information given in the passage.

Btw, I've got this passage in GMATPrep practice but did not face with question no.1. And then when I attempted this question for the first time on this forum, I chose D. I must admit that IMHO this is a difficult question, but what surprised me the most is that almost everyone commented above argued for another option. I did bookmark this post to read further comments from experts.

Hi expert GMATNinja, could you share some thoughts on Question no.1? Thank you so much!

Quite a controversial question. Though, my reasoning is more inclined towards answer choice C for the first problem. But, I still don't understand how come OA is D.

A -> not an issue
B -> type of air that would cause disturbance is not mentioned
D -> see B
E -> confuses info (see C)
C -> "To reduce refraction errors, the Chinese team carried in sea level to within five to twelve miles of Everest’s summit, decreasing the amount of air that light passed through on its way to their theodolites." so they needed to get close to get a good measurement.

Hi GMATNinja ,

Can you please put some light on the first question. It seems that option C makes sense but the OA is D.
