(Question)
Read the article and select the best answer. Article: The American economic system is organized around a basically private-enterprise, market-oriented economy in which consumers largely determine what shall be produced by spending their money in the marketplace for those goods and services that they want most. Private businessmen, striving to make profits, produce these goods and services in competition with other businessmen; and the profit motive, operating under competitive pressures, largely determines how these goods and services are produced. Thus, in the American economic system it is the demand of individual consumers, coupled with the desire of businessmen to maximize profits and the desire of individuals to maximize their incomes, that together determine what shall be produced and how resources are used to produce it. An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and responded to by producers. In the American economy, this mechanism is provided by a price system, a process in which prices rise and fall in response to demands of consumers and supplies offered by seller-producers. If the product is in short supply to the demand, the price will be bid up and some consumers will be eliminated from the market. If, on the other hand, producing more of a commodity results in reducing its cost, this will tend to increase the supply offered by seller-producers, which in turn will lower the price and permit more consumers to buy the product. Thus, price is the regulating mechanism in the America economic system. The important factor in a private-enterprise economy is that individual are allowed to own productive resources (private property), and they are permitted to hire labor, gain control over natural resources, and produce goods and services for sale at a profit. In the American economy, the concept of private property embraces not only the ownership of productive resources but also certain rights, including the right to determine the price of a product or to make a free contract with...

Read the article and select the best answer. Article: Saturday was my husband's birthday, but we spent most of the time in the car. We were driving to Phoenix for the weekend to celebrate his birthday and see the Warriors play the Suns. My husband is a lucky man. Not only has he lived to see another birthday, but he doesn't mind driving 200 miles to see an NBA basketball game. In the car, his cellphone kept ringing with birthday greetings from family and friends. He put them all on the speakerphone so he could drive with both hands and I could listen in even though it wasn't my birthday. Meanwhile, on the CD player, the Reverend AL Green began to singLove and Happiness. A little good music makes a bad road better. Four hours later, we checked into hotel, got dinner and sat out a rooftop feeling glad to be alive. We had a great weekend--we ate too much, slept too little and the Warriors, well, they lost. But still, it was worth the drive. On the way home, I started thinking about birthdays. In our family, we celebrate four in January, four in February, and all the others throughout the year. Mine is next week. I felt lucky, like my husband, I will get cards and calls and maybe a few videos. I don't need presents any more. When you've seen as many birthdays as I have seen, the only gift you truly want is to see one more. Birthdays are the mile markers on the road of life. They tell us how far we have come, but not how far we have gone. Life is a journey more than a destination. What matters is whom we choose as traveling companions, and how often we get to sit back and enjoy the ride. Question: What is the major lesson that the author took from the journey? Options: A: People should learn to appreciate life together with their loved ones. B: Taking a long drive is a great way to celebrate a birthday. C: A meaningful life is like a journey with a clear destination. D: People shouldn't rest on what they have but try to make new achievements.
