Therefore, the following practice exercises present a selection of long and short passages to help students to prepare for either the computer-based or the paperbased test. Directions: Each of the following reading comprehension questions is based on the content of the following passage. Read the passage and then determine the best answer choice for each question. Base your choice on what this passage states directly or implies, not on any information you may have gained elsewhere. One phase of the business cycle is the expansion phase. This phase is a twofold one, including recovery and prosperity. During Line the recovery period there is ever-growing (5) expansion of existing facilities, and new facil- ities for production are created. More busi- nesses are created and older ones expanded. Improvements of various kinds are made. There is an ever-increasing optimism about (10) the future of economic growth. Much capi- tal is invested in machinery or "heavy" indus- try. More labor is employed. More materials are required. As one part of the economy develops, other parts are affected. For exam- (15) ple, a great expansion in automobiles results in an expansion of the steel, glass, and rubber industries. Roads are required; thus the cement and machinery industries are stimu- lated. Demand for labor and materials results (20) in greater prosperity for workers and suppliers of raw materials, including farmers. This increases purchasing power and the volume of goods bought and sold. Thus, prosperity is diffused among the various segments of the (25) population. This prosperity period may con- tinue to rise and rise without an apparent end. However, a time comes when this phase reaches a peak and stops spiraling upwards. This is the end of the expansion phase.Which of the following statements best exemplifies the optimism mentioned in the boldfaced sentence of the passage as being part of the expansion phaseA. Public funds are designated for the construction of new highways designed to stimulate tourism.B.Industrial firms allocate monies for the purchase of machine tools.C. The prices of agricultural commodities are increased at the producer level.D. Full employment is achieved at all levels of the economy.E. As technology advances, innovative businesses replace antiquated firms.12.The layer of air next to the earth, which extends upward for about 10 miles, is known as the troposphere. On the whole, the tropo- Line sphere makes up about 75% of all the weight (5) of the atmosphere. It is the warmest part of the atmosphere because most of the. solar radi- ation is absorbed by the earths surface, which warms the air immediately surrounding it. A steady decrease of temperature with increasing (10) elevation is a most striking characteristic of this region, whose upper layers are colder because of their greater distance from the earths surface and because of the rapid radia- tion of heat into space. (Temperatures within (15) the troposphere decrease about 3.5° per 1,000-foot increase in altitude.) Within the troposphere, winds and air currents distribute heat and moisture. Strong winds, called jet streams, are located at the upper levels of the (20) troposphere. These jet streams are both com- plex and widespread in occurrence. They nor- mally show a wave-shaped pattern and move from west to east at velocities of 150 mph, but velocities as high as 400 mph have been (25) noted. The influences of changing locations and strengths of jet streams upon weather conditions and patterns are no doubt consid- erable. Current intensive research may even- tually reveal their true significance.It can be inferred from the passage that a jet plane will usually have its best average rate of speed on its run from A. New York to San Francisco B. Los Angeles to New York C. Boston to Miami D. Bermuda to New York E. London to Washington, DC 13.The layer of air next to the earth, which extends upward for about 10 miles, is known as the troposphere.

This divergence in response to evolution is commonly expressed by altering the form and function of some part or parts of the organism, the original identity of which is clearly dis- (10) cernible. For example, the creeping foot of the snail is seen in related marine pteropods to be modified into a flapping organ useful for swimming, and is changed into prehensile arms that bear suctorial disks in the squids (15) and other cephalopods. The limbs of various mammals are modified according to several different modes of life for swift running (cursorial) as in the horse and antelope; for swinging in trees (arboreal) as in the monkeys; (20) for digging (fossorial) as in the moles and gophers; for flying (volant) as in the bats; for swimming (aquatic) as in the seals, whales, and dolphins; and for other adaptations. The structures or organs that show main change in (25) connection with this adaptive divergence are commonly identified readily as homologous, in spite of great alterations. Thus, the finger and wrist bones of a bat and whale, for instance, have virtually nothing in common (30) except that they are definitely equivalent ele- ments of the mammalian limb.
