Which type of example is the one employed in the following paragraph? The most important thing to becoming rich is for you to have a mindset to want to become rich. The reason I say that is this, is because I wanted to become rich when I played Monopoly, that was, I was nine years old. The greatest formula for wealth is found on that board game. When I was nine years old my poor dad, the schoolteacher says, “Ah, put the game away. Study, study, study! You’re wasting your time playing Monopoly.” And my rich dad said, “The formula, you must open your mind and see the formula right on Monopoly.” He said, “It’s right in front of you.” And I went, “What’s the formula?” And finally I learned the formula is: four green houses, red hotel, four green houses, red hotel. Today I’m a rich man because all I ever did since the time I was 24 years old was buy four green houses, sell them all, buy a red hotel. Four green houses, red hotel. It is not, you do not have to go to school to become rich. Just play Monopoly; four green houses, red hotel. That is it. Rich Dad’s Money Making Secrets

There are four basic types of competition in business that form. a continuum from pure competition through monopolistic competition and oligopoly to monopoly. At one end of the continuum, pure competition results when every company has a similar product. Companies that deal in commodities such as wheat or corn are often involved in pure competition. In pure competition, it is often the ease and efficiency of distribution that influences purchase.

In contrast, in monopolistic competition, several companies may compete for the sale of items that may be substituted. The classic example of monopolistic competition is coffee and tea. If the price of one is perceived as too high, consumers may begin to purchase the other. Coupons and other discounts are often used as part of a marketing strategy to influence sales.

Oligopoly occurs when a few companies dominate the sales of a product or service. For example, only five airline carriers control more than 70 percent of all ticket sales in the United States. In oligopoly, serious competition is not considered desirable because it would result in reduced revenue for every company in the group. Although price wars do occur, in which all companies offer substantial savings to customers a somewhat similar tendency to raise prices simultaneously is also usual.

Finally, monopoly occurs when only one firm sells the product. Some monopolies have been tolerated for producers of goods and services that have been considered basic or essential, including electricity and water. In these eases, it is government control, rather than competition, that protects and influences sales.

Which of the following would be the best title for the passage?

A．Monopolies

B．The Commodity Market

C．The Competition Continuum

D．The Best Type of Competition
