Questions 1-10

The popularly applauded designs found in Frank Lloyd Wright's integration of architcture, landscaping and interior design, gave evidence to his belief that the form of a working or living space should follow from its function within the community.

Line Whether working on residential or commercial projects, he concentraed on creating

(5) an appropriate exterior and interior environment.

In his residentilal housing, functionality translated into a harmonious relationship with the natural flora, fauna and geographic disposition of the land. The most famous modification he implemented in his early " prairie school houses", the gently sloping roof lines that sought to capture the contours of the prairie, typified his concept of harmony with the land. Other features included, wide doorways, rooms ccentrally connected without hallways, extensive use of glass and widely overhanging eaves which provided extensive shelter. To emphasize the integrative aspects of his construction, he tried to incorporate built-in furniture wherever possible.

The Larkin Building, in Buffalo, New York, an examle of thoroughly practical factory headquarters, demonstrated that, when designing for the commercial sector, Wright's functionalism adapted itself to the projec at hand as eloquently as when he created single-family units. The building itself is of sufficient width to completely conceal the factory behind it, creating a neat, organized and efficient appearance. Even more notable than the exterior of the building, the interior displays Wright's imaginative talent to the GREatest degree.

In order to minimize on cluttered floor space, almost everything in the office was mobile, particulrly the filing cabinets, which could be completely hidden from view with a simple push. The office desks were custom designed from solid steel with special fold-out chairs that made it much easier to clean the floors. A special grade of tile was used on the walls to facilitate cleaning. The zeal which the architect devoted to integrating the building with the needs of the office environment extended to the installation of secial steel toilets which folded into the walls until needed for use.

Questions 11-20

In America, the movement of housing away from the high-rise buildings of the inner-cites originated in the 1920s, but was stalled by the GREat Depression of the 1930s and by World War II. After the war a tremendous surge occurred in the realeastate market with the advent of single-family homes on relatively small lots--typically less than one-tenth of an acre. During the 1950s, many large tract developments encroached on former farmlands near metropolitan areas. The most dramatic instances of this sprawling effect were witnessed in western municipalities such as San Jose and San Diego whose citycharters defined their boundaries over several hundred square kilometers. These large parcels of land were overrun by. standard three bedroom, two bath, "ranch-style" homes in a few short deoedes.

By the 1960s construction had subsided significantly and developers began building different kinds of plans to try and accommodate the changes in the market. Those who had taken advantage of the suburbanization trend in he post-war years had seen the value of their real estate increase dramatially and many were anxious to re-invest their assets. In an effort to reap this affluence, certain contractors moved away from the standard models and began designing larger buildings on increasingly spacious parcels even farther from city centers. Other builders began working on home to meet the needs of young couples starting new families. The townhouse, a two to three-story brick and frame structure containing more than 4 but less than 30 units per structure, wa seen as the solution. These aprtments were successful in luring many young adult city dwellers out to the suburbs.

In subsequent development, traditional single family ranch-style designs continued to be embraced, but new forms were also introduced: The condominium, a singlefamily attached dwelling; the triplex and fourplex, three-and four-family struchres; and prefabs, which have become significantly more popular durin the last 20 years owing to their low cost and ease of construction. The prefabs have the additional distinction of being mobile. It is not uncommon to see semi-trailers hauling these modular living units along the freeways to remote destinations. In a very real sense, this phenomena marks the cutting edge of suburbanization: a move out of the traditional suburbs and into areas that were formally considered wildeness.

Questions 21-30

When European explorers came across the densely clustered earthen homes of the southwestern American Indians, they described them as pueblos-the Spanish word for town or village. The name ocnveys the complexity of these ancient muti-storied buildings which marked a high point in teh enginnrng feats of the region's native people.

The earthen homes were typically built beneath a large rock overhang to take advantage of the shelter from winter rains and the hot desert sun. An additional advantage of this carefully chosen location was the ability to maintain steady internal temperatures through contact with the thermal mass of solid rock along the rear walls.

In the earliest times, the exteriors were made of sandstone blocks. Since this material was relatively soft, it was easy to cut slabs from the mountains and build thick walls mortared with mud from a nearby stream. In areas where the stone was either too difficult to cut, or where there was a short supply of suitable material, the blocks could be built from mud mixed with dried grass and small sticks, this product was known as "adobe."

Ingenious techniques were involved in the construction of the roofs. Although there were few trees available int eh desert regions, the men of the ribe would collect any lumber long enough to cover the span between the walls. These flexible poles were then interlaced with smaller sticks, and finally with small wigs and leaves. Once the covering was strong enough to walk on, river mud and dried grasses wer eapplied in several layers until a sufficient thickness had been accumulated to give the final rigid form.

The second storywas typically set back a dozen meters alowing a "front yard" for cooking, basket weaving and tanning animal skins. This teeraced effect created a spacious living environment and allowed both an organized area for domestic activities as well as an easy method of passage from one house to another.

Questions 31-42

Hydroponics, the science of growing plants in water or inert substances, represents one of the most innovative practices in moden agricultural development. Not only does it allow GREater precision of the plant growth process, it permits the production of crops in hostile in fertile environments.

The first widely publicized soilles gardeing experiments were conducted during the 1930's. W.F. Gericke, of the University of Califormai at Berkeley, varied nutrient levels among secimens suspended in a gravel substrate to demonstrate remarkable alterations in growth. Among the findings that amazed his fellow horticulturalists was the production of tomato plants over 6 meters high.

The original hydroponic gardens merely consisted of plants floating in water. It later discovered that the roots could survive in a number of media, as long as they were supplied with sufficeint moisture, nutrients and oxyen. Avariety of materials are used in recent versions including, gravel, sand, peat, sawdust, plastics and even peanut shells. Indeed, one of the most productive methods involes suspending plants in air with a styrofoam support and spraying them occasionally with nutrient solution to keep them moist.

Many different kinds of materials are suitable for physically containing plants, yet all of these systems share one trait: the culture solution. This nutrient bath is prepared in a tank by dissolving salts which provide the necessary chemicals for plant metabolism. Constant care must be taken to assure that the sodium-chloride levels in the tank do not reach excessive levels as the plants draw water and minerals out of the solution. The acidity of the tank must also be maintained aroudn 6.0 to 6.5 depending on the specific type of plants being harvested.

Although soilless farming is generally more expensive than utilizing fertile land, Herbicides and pesticides are unesessary becausue of the controlled environment. The plants also need less space to grow because their untrient uptake is significantly more efficient. The most outstanding benefit, though, is the ability to produce crops in areas with poor soil conditions or insufficient rainfall.

31. Which is NOT mentioned as a benefit of hydroponics?

(A) More control over plant growth

(B) Broader ranges of agricultural environements

(C) Production of impressive specimens

(D) Decreased costs compared to other methods

33. According to the passage, how did Gericke produce tall tomato plants?

(A) He altered the type of substrate.

(B) He demonstrated their growth to his fellow horticulturalists.

(C) He increased the acidity of their environment.

(D) He controlled their nutrition by growing without soil.

Questions 43-50

Whereas most animal teeth, including those of the odontocetes whales, are made of tough rock-like calcium, the mouths of the mystecetes whales are lined with a series of vertical, blade-like plates which hang from the upper jaw enabling them to filter their food from the seawater. Made from keratin, the same material found in fingernails, these food gathering combs are collectively referred to as a baleen. The whales fill their mouths with tons of seawater and then strain the collected mass through the baleen mats to estract tiny crustaceans such as krill, copepods and the occasional very small fish. Despite their large size, these whales have an esophagus of only a few inches in diameter which prohibits them from swallowing anything much larger than the smallest sardines. Instead of hunting for their prey, the baleen whales merely propel themselves through the fertile surface waters collecting the abundant material in their filtering apparatus.

The odontocetes, or toothed whales, have peg-like teeth which grasp prey but do not chew it, and their throats are large enough to devour entire squids, octopus and small sharks. Under ideal conditions, they feed opportunistically upon whatever is immediately available though they are capable of diving over a half mile deep in pursuit of food. As the feeding grounds of the odontocetes vary seasonally according to the availability of prey, they typically must migrae long distances.

While both the toothless mystecetes and the carnivorous odontocetes have similar physical characteristics, including an average overall isze exceeding twenty meters and a shared mammalian background, their habitats and behaviors differ due to their distinct nutritional needs. An interesting distinction is the lack of social behaviors among the toothless animals. Herding behavior demonstrates the rule among toothed whales as opposed to the baleen whales which typically travel in pairs or individually, believed to use a primitive form of communication among their peers as an aid in pursiung food.
