Question

Which two questions can be used to identify criteria for how successful the design of an efficient high altitude drone is?

A. Can it reach an altitude of 8,000 m?
B. Will it cost more than the last drone design?
C. Does it improve efficiency by 35%
D. Does it also work at low altitudes?
E. Will it become more popular than the last drone design?

Answer 1

Step-by-step explanation:

Remark

Though you do not know what height the previous drone reached, I would think reading 8000 m would be quite an accomplishment. Answer 1: A

B: I wouldn't pick B. Increased cost isn't going to contribute to design success.

C. If the efficiency is low to start with, increasing it some won't matter. On the other hand if the efficiency is moderate or good increasing it by 35% is a good thing. Let's hold on to this answer.

D: It has to work at low altitudes in order to work at high altitudes. I wouldn't pick D

E: Popularity is something you never know will happen. I think C is your best second answer.

Answer: A and C
