• Questions 53 to 57: Read the following excerpt and answer the questions below: In 1917 Marcel Duchamp took an ordinary mass-produced urinal, named it Fountain, signed his name at the bottom, declared it a work of art and placed it in a Paris museum. Medieval people would not have bothered to even argue about it. Why waste oxygen on such utter nonsense? Yet in the modern humanist world, Duchamp's work is considered an important artistic milestone. In countless classrooms across the world, first-year art students are shown an image of Duchamp's Fountain and at a sign from the teacher, all hell breaks loose. It is art! No it isn't! Yes it is! No way! After letting the students release some steam, the teacher focuses the discussion by asking "What exactly is art? And how do we determine whether something is a work of art or not?" after a few more minutes of back and forth, the teacher steers the class in the right direction: "Art is anything people think is art, and beauty is in the eye of the beholder." If people think that a urinal is a beautiful work of art - then it is. What higher authority is there that can tell people they are wrong? Today, copies of Duchamp's masterpiece are presented in some of the most important museums in the world, including the San Francisco Museum of Modern Art, the National Gallery of Canada, the Tate Gallery in London and the Pompidou Centre in Paris. The copies are placed in the museums' showrooms, not in the lavatories. Such humanist approaches have had a deep impact on the economic field as well. Suppose Toyota decides to produce the perfect car. It sets up a committee of experts from various fields: it hires the best engineers and designers, brings together the finest physicists and economists, and even consults with several sociologists and psychologists. After five years of research and development, they unveil the perfect car. Millions of vehicles are produced, and shipped to car agencies across the world. Yet nobody buys the car. Does it mean that customers are making a mistake, and that they don't know what's good for them? No. In a free market, the customer is always right. If customers don't want it, it means that it is not a good car. It doesn't matter if all the engineers, mechanics, environmentalists and all the physiologists, priests and mullahs cry out from every pulpit that this is a wonderful car - if customers reject, it is a bad car. Nobody has the authority to tell customers that they are wrong. What does the expression - "Why waste oxygen on such utter nonsense?" mean in line 3 of the first paragraph?

• Questions 66 to 70: Read the following excerpt and answer the questions below: Despite a long-term decline in the circus industry, Cirque du Soleil profitably increased revenue 22-fold over the last ten years by reinventing the circus. Rather than competing within the confines of the existing industry or trying to steal customers from rivals, Cirque developed uncontested market space that made the competition irrelevant. Cirque created what is called a blue ocean, a previously unknown market space. In blue oceans, demand is created rather than fought over. There is ample opportunity for growth that is both profitable and rapid. In red oceans existing companies in the industry compete to grab a greater share of limited demand. As the market space gets more crowded, prospects for profits and growth decline. Products turn into commodities, and increasing competition turns the water bloody There are two ways to create blue oceans. One is to launch completely new industries, as eBay did with online auctions. But it's much more common for a blue ocean to be created from within a red ocean when a company expands the boundaries of an existing industry. A blue ocean strategy encourages companies to focus less on their competitors and more on alternatives, while at the same time focusing less on their current customers and more on potential new customers. While competitive strategy would advise companies to enter attractive industries and avoid unattractive ones, blue oceans can be created in any industries, be they attractive or unattractive, stagnant or fast growing, high tech or low tech. It is all about creating new market space rather than letting the existing market structure confine strategic choices. Creating blue oceans builds brands. Along with Cirque, Southwest Airlines offers an example of successful blue ocean strategy execution. Southwest tapped into a customer base who preferred driving to air travel due to the lower cost. Instead of competing with other airlines, Southwest positioned itself as an alternative to cars and offered reduced prices, improved check-in times and increased flight frequency. Winners in a blue ocean strategy like Southwest, use 'value innovation' to drive their strategy. However, a blue ocean strategy is inherently disruptive and that makes it far riskier than a red ocean strategy. The primary purpose of the passage is to: -
• A blue-ocean strategy involves:
• A principal difference between a red ocean and a blue ocean is:
• All of the following are advantages of a blue ocean strategy except:
• A blue ocean strategy is called disruptive because:
