Article: A tent can be one of the more costly items on your camping equipment shopping list. It is definitely something that you need to consider carefully. By seeing a tent for real you will be able to get a better impression of its size and construction in the traditional shop. However,the _ is that,unless you are experienced,you may miss out some of the details that the manufacturer's promotional material makes clear. Cheap tents often look similar to the quality models they are mimicking ,but you can be sure that they use inferior materials and probably have lower design standards. Shop staff are often campers themselves. That means they usually can give lots of advice. If a shop assistant agrees with your own conclusions,that will be great;if they try to change your decision with a clear and reasonable argument,then that will be worth considering;if they just try to bamboozle ,or even bully,you then walk away. The Internet is a wonderful tool,and so long as you know how to make the most of search engines and put in a little effort,you really have the perfect answer waiting to be found. That answer will be different for every camper as each of us has different needs. Don't be surprised to see your favorite criticized somewhere,but if you see too much criticism,then you had better start thinking again. No problem. You won't have spent anything yet,so think of it positively as a large expense saved. Probably the best approach,if you have the time,is to research tents online and make a short list. Then try to inspect those tents at nearby shops. Then you can make a final decision on where to buy your chosen model based purely on total cost.

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.
