There are five basic features of services. These features distinguish them from goods. The first is that services are intangible. They are experiential in nature. One cannot taste a doctor’s treatment, or touch entertainment. One can only experience it. An important implication of this is that quality of the offer can often not be determined before consumption or before purchase. It is, therefore, important for the service providers that they consciously work on creating a desired service so that the customer undergoes a favourable experience. The second important characteristic of services is inconsistency. Since there is no standard tangible product, services have to be performed exclusively each time. Different customers have different demands and expectations. Service providers need to have an opportunity to alter their offer to closely meet the requirements of the customers. Another important characteristic of services is the simultaneous activity of production and consumption being performed. This makes the production and consumption of services inseparable. While we can manufacture a car today and sell it after, say, a month; this is often not possible with services that have to be consumed as and when they are produced. For example, the services of a teacher, doctor or lawyer. Service providers may design a substitute for the person by using appropriate technology but the interaction with the customer remains a key feature of services. Automated Teller Machines (ATMs) may replace the banking clerk for the front office activities like cash withdrawal and cheque deposit. But, at the same time, the presence of the customer, is required and his/her interaction with the process has to be managed. Services have little or no tangible components and, therefore, cannot be stored for a future use. That is, services are perishable and providers can, at best, store some associated goods but not the service itself. This means that the demand and supply needs to be managed as the service has to be performed as and when the customer asks for it. They cannot be performed earlier to be consumed at a later date. For example, a railway ticket can be stored but the railway journey will be experienced by a traveller only when the railways provide it.

Entertainment is an intangible service because it can only be:

A glass bottle that is sent to a landfill can take up to a million years to break down. By contrast, it takes as little as 30 days for a recycled glass bottle to leave your kitchen recycling bin and appear on a store shelf as a new glass container. Glass container are 100 percent recyclable, which means they can be recyclable repeatedly, again and again, with no loss of purify or quality in the glass. Recovered glass from glass recycling is the primary ingredient in all new glass containers. A typical glass container is made of as much as 70 percent recycled glass. According to industry estimates, 80 percent of all recycled glass eventually ends up as new glass containers. Every ton of glass that is recycled save more than a ton of the raw materials needed to create new glass, including 13,00 pounds of sand, 410 pounds of soda ash, and 380 pounds of limestone.
Because glass is made from natural materials such as sand and limestones, glass containers have a low rate of chemical interaction with their contents. As a result, glass can be safety reused.
Besides serving as the primary ingredient in new glass containers, recycled glass also has many other commercial uses-from creating decorative tiles and landscaping materials to rebuilding eroded beaches.

Recycling glass will help the-

Poverty can be defined as a social phenomenon in which a section of the society is unable to fulfil even its basic necessities of life. When a substantial segment of the society is deprived of the minimum level of living and continues at a bare subsistence level, that society is said to be plagued with mass poverty. The countries of the third world exhibit invariably the existence of mass poverty, although pockets of poverty exist even in the developed countries of Europe and America.

Attempts have been made in all societies to define poverty, but all of them are conditioned by the vision of minimum or good life obtaining in society. For instance, the concept of the poverty in the U.S.A. would be significantly different from that in India because the average man is able to afford a much higher level of living in the United States. There is an effort in all definitions of poverty to approach the average level of living in a society and as such these definitions reflect the coexistence of inequalities in a society and the extent to which different societies are prepared to tolerate them. For instance, inn India, the generally accepted definition of poverty emphasizes minimum level of living rather than a reasonable level of living. This attitude is borne out of a realization that it would not be possible to provide even a minimum quantum of basic needs for some decades and therefore, to talk about a reasonable level of living or good life may appear to be wishful thinking at the present stage. Thus, political considerations enter the definitions of poverty because programmes of alleviating poverty may become prohibitive as the vision of a good life widens.

What conditions the various attempts to define poverty?

Art both reflects and interprets the notion that produced it. Portraiture was the dominant theme of British painting up to the end of the eighteenth century because of a persistent demand for it. It would be unfair to say that human vanity and pride of possessions were the only reasons for this persistent demand, but certainly these motives played their part in shaping the course of British painting. Generally speaking, it is the artist's enthusiasm that accounts for the vitality of the picture, but it is the client who dictates its subject-matter. The history of national enthusiasms can be pretty accurately estimated by examining the subject-matter of a nation's art.
 There is one type of subject which recurs again and again in British painting of the late eighteenth century and the jart half of the nineteenth and which is hardly met with in the jart of any other country ---- the sporting picture, or rather the picture in which a love of outdoor life is directed into the channel of sport. The sporting picture is really an extension of the conversation piece. In it the emphasis is even more firmly based on the descriptive side of painting. It made severe demands on the artist and it must be-confessed that painters capable of satisfying these demands were rare. The ability to paint a reasonably convincing landscape is not often combined with the necessary knowledge of horses and dogs in movement and the power to introduce a portrait when necessary. To weld such diverse elements into a satisfactory aesthetic unity requires exceptional ability. It is not surprising, therefore, that while sporting pictures abound in England, especially in the private collections of country squires, not many of them are of real importance as works of art. What makes the sporting picture worth noting in, a history of British painting is the fact that it is as truly indigenous and as truly popular a form of art in England as was the religious ikon in Russia.

It' in the line 'It made severe demands on the artist were rare' refers to-

Two hundred years after Malthus predicted that population growth would overtake food production by a margin of 256 to 9, the simple fact is that food production had always been ahead of the population growth. Malthus’ doomsday prediction simply did not come true due to two major reasons: first, population did not grow geometrically and birth rates in all Western countries fell during the 20- Century, resulting in very slow population growth. Over the past quarter century, birth rates have been falling in the developing countries too. Second, modern agricultural practices and better irrigation have resulted in tremendous growth in food production in almost all parts of the globe, with the notable exception of sub-Saharan Africa. Therefore, at the global level, the Malthusian doomsday never befell on us.
India’s population grew by about two and a half times in the past 45 years — from 361 million in 1951 to an estimated 916 million in 1995. But during the same period, India’s food grain production grew by nearly four times — from 51 million tonnes in 1951 to 191 million tonnes in 1995. As a result, the per capita food grain availability in India has gone up considerably since the Independence. That is, the Malthusian prediction has not come true even in India.

The food production has always been_________of   population growth.

It's nothing short of a revolution in how we eat, and it's getting closer every day. Yes, a lot of people are obese, and yes, the definition of "healthy eating" seems to change all the time. But in labs and research centres around the world, scientists are racing to match our genes and our taste buds, creating the perfect diet for each of us, a diet that will fight disease, increase longevity, boost physical and mental performance, and taste great to boot. As food scientist J.Bruce German says, "The foods we like the most will be the most healthy for us."
Is that going to be a great day, or what?
All this will come to pass, thanks to genomics, the science that maps and describes an individual's genetic code. In the future, personalized DNA chips will allow us to assess our own inherited predispositions for certain diseases, then adjust our diets accordingly. So, if you're at risk for heart disease, you won't just go on a generic low-fat diet. You'll eat foods with just the right amount and type of fat that's best for you. You'll even be able to track your metabolism day-to-day to determine what foods you should eat at any given time, for any given activity. "Since people differ in their genetics and metabolism, one diet won't fit all," says German.
 As complex as all this sounds, it could turn out to be relatively simple.

Why won't a common diet fit everybody?

The public distribution system, which provides food at low prices, is a subject of vital concern. There is a growing realization that though India has enough food to feed its masses two square meals a day, the monster of starvation and food insecurity continues to haunt the poor in our country. Increasing the purchasing power of the poor through providing productive employment leading to rising income, and thus good standard of living, is the ultimate objective of public policy. However, till then, there is a need to provide assured supply of food through a restructured, more efficient and decentralized public distribution system (PDS). Although the PDS is extensive world – it hasn't reached the rural poor and the remote places. It remains an urban phenomenon, with the majority of the rural poor still out of its reach due to lack of economic and physical access. The poorest in the cities and the migrants are left out, for they generally do not possess ration cards. The allocation of PDS supplies in big cities is larger than in rural areas. In view of such deficiencies in the system, the PDS urgently needs to be streamlined. Also, considering the large it is one of the largest such systems in the food grains production combined with food subsidy on one hand and the continuing slow starvation and dismal poverty of rural population on the other, there is a strong case for making PDS target group oriented. By making PDS target group oriented, not only the poorest and the neediest would be reached without additional cost but we can also reduce the overall costs incurred. 

The public distribution system, which provides food at_______is a subject of vital concern. 

Read the following passage and answer the questions that follow-
Parents all over Iceland’s capital Reykjavik embark on a two-hour evening walk around their neighbourhood every weekend, checking on youth hangouts as a 10 pm curfew approaches.The walk in Reykjavik is one step toward Iceland’s success into turning around a crisis in teenage drinking.Focusing on local participation and promoting more music and sports options for students, the island nation in the North Atlantic has dried up a teenage culture of drinking and smoking. Icelandic teenagers now have one of the lowest rates of substance abuse in Europe.The Icelandic Centre for Social Research and Analysis, the institute pioneering the project for the past two decades, says it currently advises 100 communities in 23 countries, from Finland to Chile, on cutting teenage substance abuse. “The key to success is to create healthy communities and by that get healthy individuals, ” said Inga Dora Sigfusdottir, a sociology professor who founded the Youth of Iceland programme, which now has rebranded as Planet Youth.The secret, she says, is to keep young people busy and parents engaged without talking much about drugs or alcohol. That stands in sharp contrast to other anti-abuse programmes which try to sway teenagers with school lectures and scary, disgusting ads showing smokers’ rotten lungs or eggs in a frying pan to represent an intoxicated brain.
“Telling teenagers not to use drugs can backlash and actually get them curious to try them,” Ms Sigfusdottir said. In 1999, when thousands of teenagers would gather in Reykjavik every weekend, surveys showed 56% of Icelandic 16-year-olds drank alcohol and about as many had tried smoking.
Years later, Iceland has the lowest rates for drinking and smoking among the 35 countries measured in the 2015 European School Survey Project on Alcohol and Other Drugs. On average, 80% of European 16-year-olds have tasted alcohol at least once, compared with 35% in Iceland, the only country where more than half of those students completely abstains from alcohol.
Denmark, another wealthy Nordic country, has the highest rates of teenage drinking, along with Greece, Hungary and the Czech Republic, where 92% to 96% have consumed alcohol. In the US, teen drinking is a significant health concern, because many US teenagers are driving cars and do not have access to good public transport like teenagers in Europe.
Reykjavik mayor Dagur B. Eggertsson said the Icelandic plan “is all about society giving better options” for teens than substance abuse. He believes the wide variety of opportunities that now keep students busy and inspired has dramatically altered the country’s youth culture. Local municipalities like Reykjavik have invested in sport halls, music schools and youth centres.To make the programmes widely available, parents are offered a 500 US dollar
annual voucher toward sports or music programmes for their children.

Researchers say the Planet Youth prevention model is evolving constantly because it is based on annual surveys to detect trends and measure policy effectiveness. By law, introduced when Icelandic police routinely dealt with alcohol-fuelled street gatherings, children under 12 are not allowed to be outside after 8pm without parents and those 13 to 16 not past 10pm. “We tell the kids if they are out too late, polite and nice, and then they go home,” said Heidar Atlason, a veteran member of the patrol. Over Iceland’s harsh winter, one parent admits, evenings sometimes pass without running into any students.

Teenage drinking in many countries like Denmark, Greece, Hungary, etc has been reported as
