Question 41-50

If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation —— conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salts stay behind. If this is carried to the extreme, of course, white crystals of salt would be left behind.

The opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. Here the ocean is being diluted so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.

Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.

A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.

In the Weddell Sea, off Antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.

Questions 31-40

Glacier National park in Montana shares boundaries with Canada, an American Indian reservation, and a national forest. Along the North Fork of the Flathead River, the park also borders about 17,000 acres of private lands that are currently used for ranching, timber, and agriculture. This land is an important part of the habitat and migratory routes for several endangered species that frequent the park. These private lands are essentially the only ones available for development in the region.

With encouragement from the park, local landowners initiated a land-use planning effort to guide the future of the North Fork. The park is a partner in an interlocal agreement that calls for resource-managing agencies to work together and with the more than 400 private owners in the area. A draft plan has been prepared, with the objective of maintaining traditional economic uses but limiting new development that would damage park resources. Voluntary action by landowners, in cooperation with the park and the county, is helping to restrict small-lot subdivisions, maintain wildlife corridors, and minimize any harmful impact on the environment.

The willingness of local landowners to participate in this protection effort may have been stimulated by concerns that Congress would impose a legislative solution.

Nevertheless, many local residents want to retain the existing character of the area.

Meetings between park officials and landowners have led to a dramatically improved understanding of all concerns.

31. The passage mainly discusses

(A) the endangered species in Glacier National Park

(B) the protection of lands surrounding Glacier National Park

(C) conservation laws imposed by the state of Montana

(D) conservation laws imposed by Congress

32. Why are the private lands surrounding Glacier National Park so important?

(A) They function as a hunting preserve.

(B) They are restricted to government use.

(C) They are heavily populated.

(D) They contain natural habitats of threatened species.

33. The word "ones" in line 6 refers to

(A) private lands

(B) endangered species

(C) migratory routes

(D) ranching, timber, agriculture

34. The word "initiated" in line 7 is closest in meaning to

(A) started

(B) requested

(C) purchased

(D) considered

35. The relationship between park officials and neighboring landowners may best be

described as

(A) indifferent

(B) intimate

(C) cooperative

(D) disappointing

36. It can be inferred from the passage that a major interest of the officials of Glacier

National Park is to

(A) limit land development around the park

(B) establish a new Park in Montana

(C) influence national legislation

37. In lines 15-16, the author implies that landowners might be responding to environmental

concerns for which of the following reasons?
