If present trends continue, the world would face major crises by end of the century: insufficient cheap convenient energy. For without such energy, industrial production will fall, agricultural output will drop, transport will be restricted and standard of living in developed countries will plummet. At present, almost all our energy comes from fossil fuels. The earth’s reserves of fossil fuels have been formed from organic matter subjected to enormous heat and pressure of millions of years. But such reserves are finite. Because power demand is increasing very rapidly, fossil fuels will be exhausted within a relatively short time. We can estimate the amount of recoverable fuel under the surface of the earth and we know the rate at which it is being extracted. Fairly simple calculation can therefore determine its remaining life. If present trends continue, gas and oil reserves will be exhausted by the middle of the 21st century-about 70 years from now. Similar estimates for coal and wood reserves suggest a projected supply of 250-300 years. Of course long before fossil fuels are exhausted, demand will greatly exceed supply.
For too many years, the world has consumed fossil fuels with little thought for the future. In fact, world energy consumption increased almost 600% between 1900 and 1965 and it is projected to increase by another 450% between 1965 and the year 2000. Crude oil has been pumped out of the ground for about 100 years, but over half of it is been consumed in the past 18 years. Coal has been mined for over 800 years, but over a half of it has been extracted in the past 37 years. In sum, most of the world’s consumption of energy from fossil fuels throughout history has taken place within living memory.
Fossil fuels as used in the passage includes Options: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 courses of his assault on the summit; the weather, besides adding to the demand 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 is 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 must meet both these requirements and thus give to those chosen to attempt the summit and to their supporting teams some measures 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? Options:Select the option that best explains the information conveyed in the sentence.

Read the passage carefully and answer the question that follows.
Curiosity is as clear and definite as any of our urges. We wonder what is in a sealed telegram or in a letter which someone else is absorbed or what is being said in the telephone booth or in low conversation. This inquisitiveness is vastly stimulated by jealousy. Suspicion or any hint that we ourselves are directly or indirectly involved in. But there appears to be a fair amount of personal interest in other people's affairs even when they do not concern us except as a mystery to be unravelled or a tale to be told. The reports of a divorce suit will have news 'value' for many weeks, They constitute a story like a novel, a play or a moving picture. This is not an example of pure curiosity. However, since we readily identify ourselves with others' their joys and despair then become our own concern.
