[EX Q]: Article: Wal-Mart is not just the world's largest retailer . It's the world's largest company, which sells in three months what number-two retailer Home Depot sells in a year. Wal-Mart exercises its power for just one purpose: to bring the lowest possible prices to its customers. At Wal-Mart, that goal is never reached. The retailer has a clear policy for suppliers: On basic products that don't change, the price Wal-Mart will pay, and will charge shoppers, must drop year after year. But what almost no one outside the world of Wal-Mart and none of its 21,000 suppliers know is the high cost of those low prices. To survive in the face of its pricing demands, makers of everything from bikes to jeans have had to close US plants in favor of obtaining products from abroad. Indeed, the real story of Wal-Mart, the story that never gets told, is the story of the pressure the biggest retailer constantly applies to its suppliers in the name of bringing us "every day low prices". The giant retailer' s low prices often come with a high cost. Wal-Mart' s pressure can crush the companies it does business with and force them to send jobs overseas. Are we shopping our way straight to the unemployment line? Of course, US companies have been moving jobs offshore for decades, long before Wal-Mart was a retailing power. But there is no question that the chain is helping accelerate the loss of American jobs to low-wage countries such as Thailand. People ask, "How can it be bad for things to come into the US cheaply?" Sure, it's great to have bargains. But you can' t buy anything if you' re not employed. There is no question that Wal-Mart's drive to squeeze out cost has benefited consumers. By now, it is accepted wisdom that Wal-Mart makes the companies it does business with more efficient and focused. Wal-Mart itself is known for continuous improvement in its ability to handle, move, and track goods. It is legendary for forcing its suppliers to redesign everything from their packaging to their computer systems. It is also legendary for quite straightforwardly telling them what it will pay for their goods.
Question: How do suppliers meet the requirements of Wal-Mart?
Options: (A) To sell even more goods in three months. (B) To cut down the employment rate sharply. (C) To charge shoppers at a much higher price. (D) To run the business in a well-organized way.

[EX Q]: Article: A week ago, I read When Money Talks, Listen! by Rich Ezzo. It took only about an hour to read, and that included one trip to the coffee maker and about 10 distractions from Alex, our cat, who thinks he is the center of the universe. When I first received a copy, I thought it was a get-rich-quick type of publication. There is nothing wrong with that kind of book, but my mind just doesn't chase after dreams of wealth. I figure that if God ever wants me to be rich, he knows where to find my purse. When I began reading When Money Talks, Listen!, I was overjoyed to find that Rich Ezzo isn't money hungry either. He, too, is hungry for things far more important than money. I absolutely love this e-book. Why did I wait a week to write the review ? simple. I wanted to see if the impact it had on me could keep up. After reading the last word of the e-book, I totally agreed with the subtitle which promised to forever change the way we thought about money. I had so many thoughts running around my mind that I had to install a stop light to stop some while others made their way into the picture. I had a mental traffic jam, which only goes to show how slow the traffic usually is. It has been a week and the impact is the same. I guarantee this is an e-book you'll want to read. I urge you to visit the author's website, MysterMoney. Com, and to download the e-book. You won't regret it.
Question: What's the purpose of the passage?
Options: (A) to strongly recommend an e-book (B) to show the author's attitude to money (C) to introduce the general idea of an e-book (D) to tell us Rich Ezzo isn't money hungry

[EX Q]: Article: Maps of the world's population show that the majority of people today live near water. We live along coastlines, around bays, up the course of rivers and streams and on islands. We also vacation at the beach and find comfort fishing on a lake. Nothing makes small children happier than the chance of playing in water. More surprisingly, this human favor for water makes evolutionary sense. Sure, we need drinking water to live, but we have also benefited from what's swimming under the waves. Neuroscientist Crawford of the University of North London has proposed that our ancient ancestors attached to the sea, and that their devotion paid off by allowing the human species to develop large and complex brains. Crawford claims that when humans separated from apes and appeared in the forests of Africa, they stuck close to rivers and beaches and started catching fish, clams and crabs. That seafood was packed with omega-3 fatty acids, essential fatty acids that promote brain cell growth. It's no coincidence, Crawford claims, that human brain growth began to increase rapidly once we left the woods and headed for the beach. Scientists have also discovered that people who eat fish regularly are less likely to suffer from depression than those who eat less seafood. Biochemist Hibbelin of the National Institutes of Health has shown that across cultures there is a direct link between amount of fish eaten each week and rates of depression. More interestingly, Hibbelin and researcher Laura have found that fish is commonly used as a symbol of happiness and good health in various religions and cultures. We know that fish and the sea are good for us, and so we seek them out. We vacation on the coast and see the waves come and go, feeling happiness has taken over our brain. When we move inland, or go home from vacation, we lose touch with our sea roots and feel unhappy.
