Passage 1Questions 1 to 5 are based on the following passage.Industrial psychology is the application of various psychological techniques to the selection and training of industrial workers and to the promotion of efficient working conditions and techniques, as well as individual job satisfaction.The selection of workers for particular jobs is essentially a problem of discovering the special aptitudes and techniques, and personality characteristics needed for the job and of devising tests to determine whether candidates have such aptitudes and characteristics. The development of tests of this kind has long been a field of psychological research. Once the worker is on the job and has been trained, the fundamental aim of the industrial psychologist is to find ways in which a particular job can best be accomplished with a minimum of effort and a maximum of individual satisfaction. The psychologist's function, therefore, differs from that of the so-called efficiency expert, who places primary emphasis on increased production. (76) Psychological techniques used to lessen the effort involved in a given job include a detailed study of the motion required to do the job, the equipment used, and the conditions under which the job is performed. After making such a study, the industrial psychologist often determines that the job in question may be accomplished with less effort by changing the routine motions of the work itself, changing or moving the tools, improving the working conditions, or a combination of several of these methods.(77) Industrial psychologists have also studied the effects of fatigue on workers to determine the length of working time that yields the greatest productivity. In some cases such studies have proven that total production on particular jobs could be increased by reducing the number of working hours or by increasing the number of rest periods, or“breaks", during the day. Industrial psychologists may also suggest less direct requirements for general improvement of job performance, such as establishing a better line of communication between employees and management.
Passage 3Questions 11 to 15 are based on the following passage.Without proper planning, tourism can cause problems.For example, too many touristscan crowd public places that are also enjoyed by the inhabitants of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country's economy,(79) It is important to think about the people of a destination country and how tourism affects them. Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance the well-being of local inhabitants.Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country's economy can suffer.On the other hand, if there is not enough tourism, people can lose jobs.Businesses can also lose money. It costs a great deal of money to build large hotels,airports, air terminals, first-class roads, and other support facilities needed by tourist attractions.(80) For example, a major international-class tourism hotel can cost as much as 50 thousand dollars per room to build.  If this room is not used most of the time, the owners of the hotel will lose money.Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers to handle waste,and water. All of these support facilities cost money.If they are not used because there are not enough tourists, jobs and money are lost.
