1. For over fifty years, the ocean-freight industry worked to make ocean freighters faster and to lower their fuel consumption. Despite considerable success, the economics of the industry 美国GREw worse, until the industry was almost dead. What was wrong was an incongruity between assumptions and realities. The real costs came, not from time spent at sea, but from time spent in port during loading and unloading.Which of the following actions would be most likely to lead to a solution of the problem faced by the ocean-freight industry, as it is analyzed in the passage?
(A) Developing a ship’s engine that runs on a cheaper type of fuel than that traditionally used by ocean freighters
(B) Developing a ship with accessible cargo compartments that can be mechanically loaded and unloaded very rapidly
(C) Developing a ship whose freight capacity relative to the ship’s total volume is much larger than that of any existing ship
(D) Implementing a system to ensure that ocean freighters are loaded to capacity whenever they leave a port
(E) Implementing a marketing plan that focuses on routes that are known to be least threatened by unfavorable weather, thus permitting rapid trips and reliable arrival times
2. The increased concentration of salt in the bay, which is the result of recent drought and high temperatures, will cause many fish to die. Shrimp, however, can tolerate high salt levels; the shrimp industry will not, therefore, be hurt by the increased concentration of salt.
Which of the following statements, if true, would weaken the argument above?
(A) Some fish will migrate to areas that have lower concentrations of salt.
(B) Lack of rainfall for extended periods of time lowers the water level of bays.
(C) The organisms on which young shrimp feed cannot survive in such salty waters.
(D) Increased water temperature often causes shrimp to multiply more quickly.
(E) Shrimp are more abundant in areas of the bay that are sparsely populated by fish.
3. Currently people in the United States eat, on the average, 1,431 pounds of food per year, 35 pounds more than in 1980. This increase is, at least in part, because people between the ages of 15 and 64 have accounted for an increasing share of the population.
Which of the following can be properly inferred from the passage above?
(A) More than half of the current population of the United States is between the ages of 15 and 64.
(B) The population has risen since 1980.
(C) Children below the age of 15 require, on the average, more food than do people over the age of 64.
(D) Before 1980 children below the age of 15 outnumbered people between the ages of 15 and 64.
(E) Individuals between the ages of 15 and 64 consume, on the average, more food than do those younger or older.
4. Each increase of 1 percent in real disposable personal income per capita will increase the share of the electorate for an incumbent by about 2.2 percentage points, other things being equal. Since 1952 there has been a decline in real disposable income during only one presidential election year. The incumbent lost that election.英语作文
