PART II     CLOZE TEST       (15 minutes, 15 points)

Directions: For each blank in the following passage, choose the best answer from the four choices given in the opposite column. Mark the corresponding letter of your choice with a single bar across the square brackets on your Machine-scoring Answer Sheet.

We are entering a period in which rapid population growth, the presence of deadly weapons, and dwindling resources will bring international tensions to dangerous levels for an extended period. Indeed, 21 seems no reason for these levels of danger to subside unless population equilibrium is 22 and some rough measure of fairness reached in the distribution of wealth among nations. 23 of adequate magnitude imply a willingness to redistribute income internationally on a more generous 24 than the advanced nations have evidenced within their own domains. The required increases in 25 in the backward regions would necessitate gigantic applications of energy merely to extract the 26 resources.    
It is uncertain whether the requisite energy-producing technology exists, and more serious, 27 that its application would bring us to the threshold of an irreversible change in climate   28 a consequence of the enormous addition of manmade heat to the atmosphere. It is this 29 problem that poses the most demanding and difficult of the challenges. The existing 30 of industrial growth, with no allowance for increased industrialization to repair global poverty, hold 31   the risk of entering the danger zone of climatic change in as 32 as three or four generations. If the trajectory is in fact pursued, industrial growth will   33   have to come to an immediate halt, for another generation or two along that 34 would literally consume human, perhaps all life. The terrifying outcome can be postponed only to the extent that the wastage of heat can be reduced, 35 that technologies that do not add to the atmospheric heat burden—for example, the use of solar energy—can be utilized.

PART III       READING COMPREHENSION      
Section A (60 minutes, 30 points)
Directions: Below each of the following passages you will find some questions or incomplete statements. Each question or statement is followed by four choices marked A, B, C, and D. Read each passage carefully, and then select the choice that best answers the question or completes the statement. Mark the letter of your choice with a single bar across the square brackets on your Machine-scoring Answer Sheet.

Passage 1
The writing of a historical synthesis involves integrating the materials available to the historian into a comprehensible whole. The problem in writing a historical synthesis is how to find a pattern in, or impose a pattern upon, the detailed information that has already been used to explain the causes for a historical event.
  A synthesis seeks common elements in which to interpret the contingent parts of a historical event. The initial step, therefore, in writing a historical synthesis, is to put the event to be synthesized in a proper historical perspective, so that the common elements or strands making up the event can be determined. This can be accomplished by analyzing the historical event as part of a general trend or continuum in history. The common elements that are familiar to the event will become the ideological framework in which the historian seeks to synthesize. This is not to say that any factor will not have a greater relative value in the historian’s handling of the interrelated when viewed in a broad historical perspective.
The historian, in synthesizing, must determine the extent to which the existing hypotheses have similar trends. A general trend line, once established, will enable these similar trends to be correlated and paralleled within the conceptual framework of a common base. A synthesis further seeks to determine, from existing hypotheses, why an outcome took the direction it did; thus, it necessitates reconstructing the spirit of the times in order to assimilate the political, social, psychological, etc., factors within a common base.
As such, the synthesis becomes the logical construct in interpreting the common ground between an original explanation of an outcome (thesis) and the reinterpretation of the outcome along different lines (antithesis). Therefore, the synthesis necessitates the integration of the materials available into a comprehensible whole which will in turn provide a new historical perspective for the event being synthesized.  

36. The author would mostly be concerned with _____________.
A. finding the most important cause for a particular historical event
B. determining when hypotheses need to be reinterpreted
C. imposing a pattern upon varying interpretations for the causes of a particular historical event
D. attributing many conditions that together lead to a particular historical event or to single motive

37. The most important preliminary step in writing a historical synthesis would be ____________.
A. to accumulate sufficient reference material to explain an event
B. analyzing the historical event to determine if a “single theme theory” apples to the event
C. determining the common strands that make up a historical event
D. interpreting historical factors to determine if one factor will have relatively greater value

38. The best definition for the term “historical synthesis” would be ______________.
A. combining elements of different material into a unified whole
B. a tentative theory set forth as an explanation for an event
C. the direct opposite of the original interpretation of an event
D. interpreting historical material to prove that history repeats itself

39. A historian seeks to reconstruct the “spirit” of a time period because ____________.
A. the events in history are more important than the people who make history
B. existing hypotheses are adequate in explaining historical events
C. this is the best method to determine the single most important cause for a particular action
D. varying factors can be assimilated within a common base

40. Which of the following statements would the author consider false?
A. One factor in a historical synthesis will not have a greater value than other factors.
B. It is possible to analyze common unifying points in hypotheses.
C. Historical events should be studied as part of a continuum in history.
D. A synthesis seeks to determine why an outcome took the direction it did.

Passage 2
When you call the police, the police dispatcher has to locate the car nearest you that is free to respond. This means the dispatcher has to keep track of the status and location of every police car—not an easy task for a large department.
  Another problem, which arises when cars are assigned to regular patrols, is that the patrols may be too regular. If criminals find out that police cars will pass a particular location at regular intervals, they simply plan their crimes for times when no patrol is expected. Therefore, patrol cars should pass by any particular location at random times; the fact that a car just passed should be no guarantee that another one is not just around the corner. Yet simply ordering the officers to patrol at random would lead to chaos.
A computer dispatching system can solve both these problems. The computer has no trouble keeping track of the status and location of each car. With this information, it can determine instantly which car should respond to an incoming call. And with the aid of a pseudorandom number generator, the computer can assign routine patrols so that criminals can’t predict just when a police car will pass through a particular area.
(Before computers, police sometimes used roulette wheels and similar devices to make random assignments.)
Computers also can relieve police officers from constantly having to report their status. The police car would contain a special automatic radio transmitter and receiver. The officer would set a dial on this unit indicating the current status of the car—patrolling, directing traffic, chasing a speeder, answering a call, out to lunch, and so on. When necessary, the computer at headquarters could poll the car for its status. The voice radio channels would not be clogged with cars constantly reporting what they were doing. A computer in the car automatically could determine the location of the car, perhaps using the LORAN method. The location of the car also would be sent automatically to the headquarters computer.

41. The best title for this passage should be ___________.
A. Computers and Crimes
B. Patrol Car Dispatching
C. The Powerful Computers
D. The Police with Modern Equipment

42. A police dispatcher is NOT supposed to _____________.
A. locate every patrol car
B. guarantee cars on regular patrols
C. keep in touch with each police car
D. find out which car should respond to the incoming call

43. If the patrols are too regular, _____________.
A. the dispatchers will be bored with it
B. the officers may become careless
C. the criminals may take advantage of it
D. the streets will be in a state of chaos

44. The computer dispatching system is particularly good at ______________.
A. assigning cars to regular patrols
B. responding to the incoming calls      
C. ordering officers to report their location
D. making routine patrols unpredictable

45. According to the account in the last paragraph, how can a patrol car be located without computers?
A. Police officers report their status constantly.
B. The headquarters poll the car for its status.
C. A radio transmitter and receiver is installed in a car.
D. A dial in the car indicates its current status.
