Question

Q1. Data on planes returning from bombing missions was used to study of the vulnerability of airplanes to enemy fire. Analyzing the pattern and frequency of hits from enemy gunfire, it was seen that some parts of planes were hit disproportionately more often than other parts. How could these planes be optimally reinforced with armor plating? There were tradeoffs to consider. Every addition of plating added to the weight of the plane, decreasing its performance. Therefore, reinforcements needed to be added only to the most vulnerable areas of the planes.

CAT 2021

A
The parts hit disproportionately more than the others have to be reinforced as those received the maximum amount of damage.
B
No conclusion can be drawn as the data set is incomplete. There is no data on the planes shot down.
C
The parts with the least damage have to be reinforced, as the returning planes have survived attacks to the most damaged areas.
D
Reinforcements have to be added to all areas of the plane.
Solution
