??Questions 6 to 10 are based on the following passage:

In cities with rent control,the city government sets the maximum（最高的）rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartments. The irrent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after along time, rent control may have negative（负面的）effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also berent-controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end resul to frent control is a short age of apartments in the city.

Some theorists argue that the minimum(最低的) wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low-paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. The price, which is the wage that employers must pay, increases. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim that an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.

Supporters of the minimum wage say that it helps people keep their dignity(尊严）Because of the law, workers cannot sell their services for less than the minimum. Further more, employers cannot force workers to accept jobs at unfair wages. Economic theory predicts there sults of economic decisions such as decisions about farm production, rent control，and the minimum wage. The predictions may be correctonly if “other things are equal”. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.
