English is the study of the English language. The goal is to improve communication skills by practicing listening, speaking, reading, writing, and understanding language rules like pronunciation, vocabulary, and grammar.

The stadium was seething with people when we entered?
Options:If our thoughts is to be clear and we are to succeed in communicating it to other people, we must have some method of fixing the meaning of the words we use. When we use a word whose meaning is not certain, we may well be asked to define it. There is a usual traditional device for doing this by indicating the class to which whatever is indicated by the term belongs and also other particular property which distinguishes it from all other members of the same class. Thus we may define a whale as a ‘marine animal that spouts’. ‘Marine animals’ in this definition indicates the general class to which the whale belongs and ‘spouts’ indicates the particular property that distinguishes whales from other such marine animals as fishes, seals, jellyfish and lobsters. In the same way, we can define an even number as a finite integer divisible by two or a democracy as a system of government in which the people themselves rule.
there are other ways, of course of indicating the meaning of words. We may for example, find it hard to make a suitable definition of the word ‘animal’, as we say that an animal is such a thing as a rabbit, dog fish or goat. Similarly, we may say that religion is such a system as Christianity, Islam, Judaism and Buddhism. This way of indicating the meaning of a term by enumerating examples of what it includes is obviously of limited usefulness. If we indicate our use of the word ‘animal’ as above, our hearers might for example be doubtful whether a sea-anemone or a slug was to be included in the class of animals. It is however, a useful way of supplementing a definition if the definition itself id definite without being easily understandable. Failure of an attempt at definition to serve its purpose may result from giving as distinguishing mark one which either does not belong to all the things the definition id intended to include, or does belong to some members of the same general class which the definition is intended to exclude.

Options:So far I have been speaking of science in its universality, viewed from the perspective of the world at large. For the context of our own country and our sister developing countries, many of the factors mentioned earlier are not very important. For example, pollution, deterioration of the environment and population explosion are not yet serious problems for us in this country.
Let me now turn to a more specific area, namely the question of scientific choice for developing countries. There is no doubt that role which science s and technology have played in the upliftment of the material and economic well-being of the developed nation will, and does, influence the criteria that the Third World nations must choose in order to establish their science policies and priorities.
But the criteria to be used by this nation do not have the same as those which have brought the developed countries to their present stage of evolution. For while human beings have the same problems, their solutions, to be meaningful will have to be sought within some relevant frame of reference, such as the available resources and expertise, social values, place and time in the historical scale.
According to the passage, the basic consideration for developing science and technology should be three of the following.1. Technical know-how
2. availability of raw material
3. atmospheric pollution
4. the people's tradition and beliefs
5. population
6. capital
Options: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.
