When it comes to the alarm failure and the canary in "Feathered Friend," we can answer the questions in the following manner:
- The first alarm does not go off and the back-up alarm had not been connected just yet.
- Some potential problems with using a canary rather than an electronic alarm are: The canary may die for some natural reason, which will lead people to think there is something wrong with the air. Also, people may be far away and not see the fainted canary, whereas they would still hear an electronic alarm.
- (This is a an example of a personal opinion) Both can be reliable, but also both can have problems. Canaries have been used in underground mines and helped save people lives for centuries. Electronic alarms are usually efficient, but a problem with the circuit may lead to malfunction.
<h3>What happens in "Feathered Friend"?</h3>
In the story, Sven brings a canary with him to the space station. He wants to see the effects of low gravity on the bird. However, the bird ends up saving everyone's lives.
Sven notices the bird has fainted, and he has knowledge of canaries being used in mines to alert workers about the quality of the air. He quickly assumes there is not enough oxygen.
It turns out that their electronic alarm <u>failed</u> to go off for some reason. Had Sven not brought the bird with him, the crew would have died due to lack of oxygen.
