MCQ-> Directions : In the following questions, you have two brief passages with 5 questions in each passage, Read the passages carefully and choose the best answer to each question out of the four alternatives. PASSAGE -I Stuck with be development dilemma? Stay away from management courses. Seriously, one of the biggest complaints that organisations have about management courses is that they fail to impact the participants' on-the-job behaviour. Some management trainers stress the need for follow-up and reinforcement on the job. Some go so far as briefing the participants' managers on what behaviour they should be reinforcing back on the job. Others include a follow-up training day to review the progress of the participants. None of this is really going far enough. The real problem is that course promoters view development as something which primarily, takes place in a classroom. A course is an event and events are, by definition limited in time. When you talk about follow-up after a course, it is seen as a nice idea, but not as an essential part of the participants' development programme. Any rational, empowered individual should be able to take what has been learnt in a course and transfer it to the work place or so the argument goes. Another negative aspect of the course mindset is that, primarily, development is thought to be about skill-acquisition. So, it is felt that the distinction between taking the course and behaving differently in the work place parallels the distinction between skill-acquisition and skill-application. But can such a sharp distinction be maintained ? Skills are really acquired only in the context of applying them on the job, finding them effective and therefore, reinforcing them. The problem with courses is that they are events, while development is an on-going process which, involves, within a complex environment, continual interaction, regular feedback and adjustment. As we tend to equate development with a one-off event, it is difficult to get seriously motivated about the follow-up. Anyone paying for a course tends to look at follow-up as an unnecessary and rather costly frill. PASSAGE II One may look at life, events, society, history, in another way. A way which might, at a stretch, be described as the Gandhian way, though it may be from times before Mahatma Gandhi came on the scene. The Gandhian reaction to all the grim poverty, squalor and degradation of the human being would approximate to effort at self-change and self-improvement, to a regime of living regulated by discipline from within. To change society, the individual must first change himself. In this way of looking at life and society, words too begin to mean differently. Revolution, for instance, is a term frequently used, but not always in the sense it has been in the lexicon of the militant. So also with words like peace and struggle. Even society may mean differently, being some kind of organic entity for the militant, and more or less a sum of individuals for the Gandhian. There is yet another way, which might, for want of a better description, be called the mystic. The mystic's perspective measures these concerns that transcend political ambition and the dynamism of the reformer, whether he be militant or Gandhian. The mystic measures the terror of not knowing the remorseless march of time:he seeks to know what was before birth, what comes after death. The continuous presence of death, of the consciousness of death, sets his priorities. and values: militants and Gandhians kings and prophets must leave all that they have built:all that they have un-built and depart when messengers of the buffalo-riding Yama come out of the shadows. Water will to water, dust to dust. Think of impermanence. Everything passes.What is the passage about?

MCQ-> I suggest that the essential character of the Trade Cycle and, especially, the regularity of time-sequence and of duration which justifies us in calling it a cycle, is mainly due to the way in which the marginal efficiency of capital fluctuates. The Trade Cycle is best regarded, I think, as being occasioned by a cyclical change in the marginal efficiency of capital, though complicated and often aggravated by associated changes in the other significant short period variables of the economic system.By a cyclical movement we mean that as the system progresses in, e.g. the upward direction, the forces propelling it upwards at first gather force and have a cumulative effect on one another but gradually lose their strength until at a certain point they tend to be replaced by forces operating in the opposite direction; which in turn gather force for a time and accentuate one another, until they too, having reached their maximum development, wane and give place to their opposite. We do not, however, merely mean by a cyclical movement that upward and downward tendencies, once started, do not persist for ever in the same direction but are ultimately reversed. We mean also that there is some recognizable degree of regularity in the time-sequence and duration of the upward and downward movements. There is, however, another characteristic of what we call the Trade Cycle which our explanation must cover if it is to be adequate; namely, the phenomenon of the ‘crisis’ the fact that the substitution of a downward for an upward tendency often takes place suddenly and violently, whereas there is, as a rule, no such sharp turning-point when an upward is substituted for a downward tendency. Any fluctuation in investment not offset by a corresponding change in the propensity to consume will, of course, result in a fluctuation in employment. Since, therefore, the volume of investment is subject to highly complex influences, it is highly improbable that all fluctuations either in investment itself or in the marginal efficiency of capital will be of a cyclical character.We have seen above that the marginal efficiency of capital depends, not only on the existing abundance or scarcity of capital-goods and the current cost of production of capital- goods, but also on current expectations as to the future yield of capital-goods. In the case of durable assets it is, therefore, natural and reasonable that expectations of the future should play a dominant part in determining the scale on which new investment is deemed advisable. But, as we have seen, the basis for such expectations is very precarious. Being based on shifting and unreliable evidence, they are subject to sudden and violent changes. Now, we have been accustomed in explaining the ‘crisis’ to lay stress on the rising tendency of the rate of interest under the influence of the increased demand for money both for trade and speculative purposes. At times this factor may certainly play an aggravating and, occasionally perhaps, an initiating part. But I suggest that a more typical, and often the predominant, explanation of the crisis is, not primarily a rise in the rate of interest, but a sudden collapse in the marginal efficiency of capital. The later stages of the boom are characterized by optimistic expectations as to the future yield of capital goods sufficiently strong to offset their growing abundance and their rising costs of production and, probably, a rise in the rate of interest also. It is of the nature of organized investment markets, under the influence of purchasers largely ignorant of what they are buying and of speculators who are more concerned with forecasting the next shift of market sentiment than with a reasonable estimate of the future yield of capital-assets, that, when disillusion falls upon an over-optimistic and over- bought market, it should fall with sudden and even catastrophic force. Moreover, the dismay and uncertainty as to the future which accompanies a collapse in the marginal efficiency of capital naturally precipitates a sharp increase in liquidity-preference and hence a rise in the rate of interest. Thus the fact that a collapse in the marginal efficiency of capital tends to be associated with a rise in the rate of interest may seriously aggravate the decline in investment. But the essence of the situation is to be found, nevertheless, in the collapse in the marginal efficiency of capital, particularly in the case of those types of capital which have been contributing most to the previous phase of heavy new investment. Liquidity preference, except those manifestations of it which are associated with increasing trade and speculation, does not increase until after the collapse in the marginal efficiency of capital. It is this, indeed, which renders the slump so intractable. Which of the following does not describe the features of cyclical movement?
