MCQ-> Study the information given below and answer the questions.The following table contains the pre and post revision pay structure of a Government department

The revision has been done based on the following terms: -In pre-revised pay scale, the basic pay is the sum of the minimum pay in the appropriate pay scale and the admissible increment. After revision, the basic pay is the sum of minimum pay in the appropriate pay scale and the respective grade pay and the admissible increments. -Annual increment of 3% of the basic pay (on a compounded basic) is paid under the revised pay rules. -Monthly Dearness Allowance (DA) is calculated as percentage of basic pay. -In pre-revised pay scales, the increment was given after the completion of each year of service, but, after revision annual increments are given only in the month of July every year and there should be a gap of six months between the increments. The employees who had joined the department in the month of September, October, November and December are given an increment at the time of revised pay fixation in September, 2008. The revised pay is applicable from 1st September, 2008.Abhijit joins the department on November 10, 2006 in the pay scale of Rs. 18,400-500-22,400 with the pay of Rs. 18,400 plus 2 increments. What is his basic salary, after revision, on August 1, 2009?

MCQ->The problem of traffic congestion in Athens has been testing the ingenuity of politicians and town planners for years. But the measures adopted to date have not succeeded in decreasing the number of cars en the roads in the city centre. In 1980, an odds and evens number- plate legislation was introduced, under which odd and even plates were banned in the city centre on alternate days, thereby expecting to halve the number of cars in the city centre. Then in 1993 it was decreed that all cars in use in the city centre must be fitted with catalytic converters; a regulation had just then been introduced, substantially reducing import taxes on cars with catalytic converters, the only condition being that the buyer of such a ‘clean’ car offered for destruction a car at least 15 years old.Which one of the following options, if true, would best support the claim that the measures adopted to date have not succeeded?....

MCQ-> The income disparity in the new India is massive: 36 billionaires in India and 800 million people living on less than $2 a day. The challenge for achieving inclusive growth relates to the revival of agriculture. Farming is becoming a non-viable activity. A confluence of factors, from poor rainfall to the new availability of consumer goods which consume much of Indian familie's incomes, has driven many farmers into crushing debt. The agriculture sector has many problems with a growth rate of less than 2% in the last decade. Further scope for increase in net sown area is limited. Disparity in productivity across regions and crops has persisted. Far from benefiting from the economic boom, many complain that banks don't offer the rural poor credit, forcing them to turn to greedy money-lenders, who typically charge up to 20% interest on a four-month loan. Healthcare and education costs have risen dramatically, while the global price of cotton has become depressed, largely due to the billions of dollars in subsidies Washington hands out to U.S. farmers. The approach to the revival of Indian agriculture seems to be incremental, rather than a holistic strategy. It is important to stress that growth and equity should be pursued simultaneously rather than following the 'growth first and equity next' approach. What are the challenges for achieving 4% growth and equity in agriculture? Policy makers like the National Commission on Farmers mention cost reduction in agriculture as important to compete in a globalised world. The most important problem for the farmers is output price fluctuations. There is a big gap between producer prices and consumer prices. In order to protect farmers from National and international price volatility, a price stabilization fund is needed. The supply and demand side constraints have to be removed to raise growth. The support systems have to be tuned to improve productivity and incomes of farmers with emphasis on small and marginal farmers and dry land areas. One of the differences between the green revolution in the 1960s / 70s and the present 'second green revolution' is that risk is higher in the latter approach as it has to concentrate more on dry-land areas. Trade liberalisation has also raised the risk and uncertainty. Thus, policymakers have to keep in mind the increasing risk in agriculture. Agriculture policies have to be gender sensitive too since the share of women is increasing. The Government is aware that the crop sector may not be able to grow at 4% per annum but horticulture and allied activities like dairying, poultry and fisheries have to grow at the rate 6 % to 7 % to achieve 4% growth in agriculture. Investment in irrigation and rural infrastructure is important for agricultural growth. It is known that public investment in agriculture is lower than the requirements needed for achieving 4% growth. Bharat Nirman Programme is in the right direction but the progress has to be much fasterWhat does the author view as a challenge for achieving inclusive growth?

MCQ-> Throughout human history the leading causes of death have been infection and trauma, Modem medicine has scored significant victories against both, and the major causes of ill health and death are now the chronic degenerative diseases, such as coronary artery disease, arthritis, osteoporosis, Alzheimer’s, macular degeneration, cataract and cancer. These have a long latency period before symptoms appear and a diagnosis is made. It follows that the majority of apparently healthy people are pre-ill.But are these conditions inevitably degenerative? A truly preventive medicine that focused on the pre-ill, analyzing the metabolic errors which lead to clinical illness, might be able to correct them before the first symptom. Genetic risk factors are known for all the chronic degenerative diseases, and are important to the individuals who possess them. At the population level, however, migration studies confirm that these illnesses are linked for the most part to lifestyle factors — exercise, smoking and nutrition. Nutrition is the easiest of these to change, and the most versatile tool for affecting the metabolic changes needed to tilt the balance away from disease.Many national surveys reveal that malnutrition is common in developed countries. This is not the calorie and/or micronutrient deficiency associated with developing nations (type A malnutrition); but multiple micronutrient depletion, usually combined with calorific balance or excess (Type B malnutrition). The incidence and severity of Type B malnutrition will be shown to be worse if newer micronutrient groups such as the essential fatty acids, xanthophylls and falconoid are included in the surveys. Commonly ingested levels of these micronutrients seem to be far too low in many developed countries.There is now considerable evidence that Type B malnutrition is a major cause of chronic degenerative diseases. If this is the case, then t is logical to treat such diseases not with drugs but with multiple micronutrient repletion, or pharmaco-nutrition’. This can take the form of pills and capsules — ‘nutraceuticals’, or food formats known as ‘functional foods’, This approach has been neglected hitherto because it is relatively unprofitable for drug companies — the products are hard to patent — and it is a strategy which does not sit easily with modem medical interventionism. Over the last 100 years, the drug industry has invested huge sums in developing a range of subtle and powerful drugs to treat the many diseases we are subject to. Medical training is couched in pharmaceutical terms and this approach has provided us with an exceptional range of therapeutic tools in the treatment of disease and in acute medical emergencies. However, the pharmaceutical model has also created an unhealthy dependency culture, in which relatively few of us accept responsibility for maintaining our own health. Instead, we have handed over this responsibility to health professionals who know very little about health maintenance, or disease prevention.One problem for supporters of this argument is lack of the right kind of hard evidence. We have a wealth of epidemiological data linking dietary factors to health profiles/ disease risks, and a great deal of information on mechanism: how food factors interact with our biochemistry. But almost all intervention studies with micronutrients, with the notable exception of the omega 3 fatty acids, have so far produced conflicting or negative results. In other words, our science appears to have no predictive value. Does this invalidate the science? Or are we simply asking the wrong questions?Based on pharmaceutical thinking, most intervention studies have attempted to measure the impact of a single micronutrient on the incidence of disease. The classical approach says that if you give a compound formula to test subjects and obtain positive results, you cannot know which ingredient is exerting the benefit, so you must test each ingredient individually. But in the field of nutrition, this does not work. Each intervention on its own will hardly make enough difference to be measured. The best therapeutic response must therefore combine micronutrients to normalise our internal physiology. So do we need to analyse each individual’s nutritional status and then tailor a formula specifically for him or her? While we do not have the resources to analyze millions of individual cases, there is no need to do so. The vast majority of people are consuming suboptimal amounts of most micronutrients, and most of the micronutrients concerned are very safe. Accordingly, a comprehensive and universal program of micronutrient support is probably the most cost-effective and safest way of improving the general health of the nation.The author recommends micronutrient-repletion for large-scale treatment of chronic degenerative diseases because
