Question 20
ComprehensionJAMB 1978 Passage D
These two factors, the altitude and the weather, tend separately and together to defeat the climber. The height weakens, slows him down; it forces him to spend days and nights in the course of his assault on the summit; the weather, besides adding to the demands of his energy and moral fortitude, conspires to deny him the time he needs to complete his mission. Whereas in lower mountains and on easy ground the weather may be no more than a handicap, in the high Himalayas it is decisive, regardless of terrain.
The deduction to be drawn from these two factors was clear enough. We must either so fortify ourselves that we could continue, without detriment, to live and have our being above the limit of natural acclimatization, or, better still, we must solve the problem of speed. It was desirable, in fact, that we should meet both these requirements and thus give to those chosen to attempt the summit and to their supporting teams some measure of insurance against the vagaries of the weather, for safety in mountain climbing is as much a matter of swiftness as of sureness of foot. Either or both could be achieved only by the administration of oxygen in sufficient quantities to make up for the deficiency in the air, and for the duration of the upward journey above the limit of successful acclimatization.

Which ONE of the following was NOT a reason for using oxygen?
- A.It gave them psychological encouragement.
- B.It fortified them to live above the limit of natural acclimatization
- C.It protected them against the unexpected changes of the weather
- D.It quickened their journey to the summit
- E.It helped them to survive the worst effects of the weather.
Show the answer and explanation
Answer: A (It gave them psychological encouragement.)
Explanation
The passage gives oxygen as the way to live above the acclimatization limit, to climb faster and to be safer from the weather. It never mentions psychological encouragement.
