单选题To meet the challenges, companies need to be_________than before about how they recruit and retain workers.

单选题. Today supermarkets are found in almost every large city in the world. But the first supermarket was opened only fifty years ago. It was opened in New York by a man named Michael Cullen. A supermarket is different from other stores in several ways. In supermarkets, goods are placed on open shelves. The customers choose what they want and take them to the check-out counter. This means that fewer employees are required than in other stores. The way products are displayed is another difference between supermarkets and many other types of stores. For example, in supermarkets, there is usually a display of small inexpensive items just in front of the check-out counter: candies, chocolates, magazines, cheap books and so on. Why are they there? Most customers who go to a supermarket buy from a shopping list. They know exactly what they need to buy. They shop according to a plan. By the time he or she reaches the check-out counter, the customer is feeling pleased and relaxed because the task is finished. In this happy mood, the customer sees an attractive display of inexpensive goods that were not on her shopping list. Now she feels like buying something just for her own pleasure and enjoyment. Many customers buy from these displays of products near the check-out counter, and this is exactly what the owner of the supermarket hopes they will do. Another important fact in helping a customer choose what to buy, is where a product is placed on a shelf. A product that is placed at eye level on a shelf sells much better than one which is placed on a lower or higher shelf. A product which is easy to see sells best. Manufacturers pay a higher price to have their products placed at eye level on the shelves. The comfort and convenience of shopping centers is another factor which makes them popular with customers. Large parking spaces are provided, and many supermarkets stay open until very late at night.1. According to the passage, which statement is true?

单选题. Many countries face a somewhat more serious economic problem in the form of an unfavorable trade balance (贸易逆差) with other nations. Such an imbalance exists when the total value of a country's imports exceeds that of its exports. For example, if a country buys $25 billion of products from other countries, yet sales only $10 billion of its own products overseas, its trade deficit is $15 billion. Many underdeveloped nations find themselves in this position because they lack natural resources or the industrial capacity to use these resources, and thus have to import raw materials or manufactured goods. One effect of a trade deficit is the flow of currency (货币) out of a country. In the case of an underdeveloped nation, this can cause many financial difficulties, including failure to meet debt payments and obstacles to creation of an industrial base. Even in the case of a fully developed nation such as the United States, a large trade deficit is reason for alarm. American products, made by well-paid workers in US industries, cost more to produce than those made in places like Asia, where labor and material costs are much lower. Money spent on foreign products is money not spent on items produced by domestic industries.1. What does the passage mainly discuss?
