Question 4 of 9

Read the following passage:
Mountains are formed in many ways. Dome mountains are formed when pressure from melted rock pushes up at the ground. Over thousands of years this pressure makes a mountain. Fault block mountains form when faults, or cracks, in earth’s surface force some rocks up. This is how the Rocky Mountains in North America were formed. Another type of mountain is a fold mountain. Fold mountains occur when two of earth’s land masses collide forcing rocks up along the edges. No matter how mountains form, the process takes a very long time.

This passage mainly describes:
         
   A. how earth's plates move
   B. the ways that mountains are formed
   C. that it takes a long time to make a mountain
   D. how fold mountains are formed
 

Question 5 of 9

Kudzu: The Vine That Ate the South

Kudzu is not a native southern plant. It actually came from Japan. It was introduced to the United States in 1876 at the Centennial Exposition in Philadelphia, Pennsylvania. The large leaves and fragrant blossoms of the kudzu plant attracted American gardeners who first used it for ornamental purposes. By the 1920s it was being used to feed cattle and other livestock.

The climate in the southeastern part of the United States is perfect for kudzu. During the summer the vines can grow as much as a foot per day and average sixty feet every year. These vines climb power poles, trees, buildings, and anything else they come into contact with. This feature was what initially led the Soil Conversation Service to use kudzu for soil erosion. It was during the Great Depression of the 1930s, that the Civilian Conservation Corps planted kudzu all over the south.

Unfortunately, kudzu grew too well and began killing trees by smothering them. Once a tree has been blanketed by kudzu, little light can penetrate, and the trees die from lack of sunlight. Over the years many valuable forests have been destroyed.

By 1953, the United States government stopped promoting the use of kudzu and instead began searching for ways to control its growth. Kudzu has no natural enemies in the United States, so the U.S. Forest Service began searching for methods to control it. Many herbicides were used on kudzu, but most had very little effect on its growth. Kudzu which has been established for at least ten years presents even greater problems for eradication. Today southerners continue to struggle with the rampant growth of the kudzu vine, and many refer to it as "the vine that ate the South."

 
What is the main idea of this passage?
         
   A. Although kudzu has many uses, its uncontrolled growth has become a major problem.
   B. At one time the United States government promoted the use of kudzu.
   C. Kudzu is an ornamental plant.
   D. Kudzu is used to feed animals in the south.
 

Question 6 of 9

Vitamin D is an important vitamin that we all need. However, it can also be poisonous in huge amounts. Some early Arctic explorers suffered from Vitamin D poisoning.

In the Arctic, explorers often ate large amounts of animal fat. The fat is high in calories. These calories were necessary to maintain body heat in extremely cold environments.

Vitamin D was stored in body fat. By eating more fat than other foods, explorers were gradually poisoning themselves. Since it was stored in fat, Vitamin D would build up in the bodies of the explorers until it reached a toxic level. Several explorers were killed, not by the Arctic dangers but by the food they ate.

 
What would be a good topic sentence for this passage?
         
   A. Vitamin D is a fat soluble vitamin.
   B. Vitamin D is both necessary and harmful.
   C. Early Arctic explorers faced many hardships.
   D. In the past, people often died while exploring.
