DUE IT 15 MINUTES I WILL GIVE BRAINLIEST AND 45 POINTS "An Early Missile Guidance System"

In December of 1941, the United States of America entered World War II. During the next four years, the nation would be called upon to make great personal sacrifices and to arrive at innovative solutions to life and death problems on a global scale. The nation’s creative energies were harnessed as they had never been before. Some of the ideas and plans that were implemented during that period were brilliant. Others were discarded as impractical. Some of the initiatives displayed a rare and brash boldness typical of the American spirit. The story you are about to read is one of these.

Early in the war the nation’s military began to think seriously about the development of a guided missile system of the type routinely used in military engagements today. The potential benefits were clear. An unmanned missile system would be cost-efficient, since people would not have to be trained to fly it. If we could guide an unmanned missile toward an enemy target, the likelihood of hitting the target would be increased. American lives would be preserved and enemy strength would be weakened. Also, our military knew that the Germans were working on an unmanned missile system. Thus, they urgently sought a solution to the guidance problem. A potential solution came from an unlikely source: Dr. B. F. Skinner, a nationally prominent psychologist.

Dr. Skinner made an appointment to demonstrate his system to a room full of high-level military decision makers. The demonstration was very successful. The guidance system was small and performed with high levels of accuracy on test targets. Then, one of the enthusiastic military observers asked for an explanation of how the system worked. Dr. Skinner responded by opening the case housing the system. Inside was a pigeon that had been trained to keep a pointer on a moving target. The pigeon controlled the pointer by pecking at a bar that determined the pointer’s position. Dr. Skinner controlled the pigeon’s behavior by the use of rewards. When the bird was performing the task successfully, small food pellets were automatically dispensed. This encouraged the bird to perform its assigned task as successfully as possible.

As you might guess, Dr. Skinner’s solution was a bit too bold for adoption by the military. Nonetheless, in my view, it was an innovative solution to what at the time was a difficult problem to solve.

from "An Early Missile Guidance System"

Which is the best summary of the third paragraph?

A. Dr. Skinner demonstrated an unmanned missile guidance system that had a high degree of accuracy. When asked how it worked, Skinner revealed a pigeon who had been trained through a reward system to keep a pointer on a target.

B. Dr. Skinner showed military personnel how a pigeon could help solve their missile guidance problems. He put the pigeon in a case and fed it when it pecked at a pointer that would keep the missile on target.

C. Military personnel were highly amused when Dr. Skinner showed them an unmanned missile guidance system that was powered by a pigeon. The pigeon was rewarded with food for keeping a pointer on a target.

D. Military personnel allowed Dr. Skinner to present his accurate yet bold system of unmanned missile guidance. He used a pigeon that was rewarded with food to keep the missile on target.
