HS6151 ENG 1 Important Questions
Read the Passage and answer the question that follows it: Considering the enormous number of things which could turn a space mission into a fatal disaster, it is remarkable that there have been so few accidents. 1967 was a bad year; in January, the Americans lost three astronauts in a fire which occurred during tests on the ground and, in April, the Russians lost astronaut komarov landing after sixteen successful Earth orbits. The accident was due to a parachute failure. Neither of these tragedies was quite what the world had expected. It was feared that one day astronauts would be strande4d in space, alive but with no possibility of returning to Earth. This very nearly happened in 1970 during the flight of Apollo
The life-support and other systems of spacecraft are interlinked. This means that if one system fails it is likely to cause other systems to fail too. Designers have tried to avoid disasters by duplicating, and in some cases triplicating, important pieces of equipment; for example , Apollo has no less than three fuel cells. Even so, a breakdown in the service module of Apollo 13 was nearly fatal.
On 13 April one of the low temperature oxygen tanks in the service modulesuddenly broke open; the explosion probably damaged the other oxygen tank close beside it. The exact reason for the explosion may never be known.the important point to note is that the oxygen from these tanks is not only used by the crew but also feeds the fuel cells and fuel cells produce electrical power and water. So, one failure immediately caused a major power failure affecting nearly every system in the command module and produced a shortage of oxygen and water for life-support.
(a)write a response which best reflects the meaning of the text:
i. 1967 was
- 1. A good year for the Russians and Americans.
- 2. A good year for the Americans but not for the Russians.
- 3. A bad year for the Americans and the Russians.
- 4. A bad year for the Americans but not for the Russians.
ii. Why was the breakdown of the oxygen supply so important?
- 1. Because it could cause an explosion.
- 2. Because they could not fire their rocket without it.
- 3. Because they never found out the reason for it.
- 4. Because it affected all the systems in the module.
