Question 1: Word Structure Context Clue

Answer:

Sometimes simply knowing the meaning of basic prefixes, suffixes, and root words can help the reader make an educated guess about an unknown word.

Question 2: Blood Pressure

The body is composed of systems that have evolved and diversified in order to maintain the natural functions and processes they regulate. One such system that has these regulators is the body's cardiovascular system. The body's pump, which regulates the flow of vitally needed oxygen to all cells of the body, as well as the discard of carbon dioxide and other waste products, is the heart.Because blood pressure varies at different points within the body, differing components are needed to keep the body's blood pressure regulated. Three of the basic components are baroreceptors, chemoreceptors, and the kidneys.Baroreceptors are stretch receptors composed of fine branching nerve endings and are contained along the walls of the arteries near the heart and in other areas of the body as well.Impulses are related to this stretching along the arterial walls, which causes these baroreceptors to send out even more impulses to the heart, arteries, and veins, causing the blood pressure to go either up or down.Chemoreceptors are located along the walls of the arteries and monitor changes in oxygen level, carbon dioxide, and pH. Just think! A fall in oxygen causes receptors to send impulses to raise the blood pressure.The kidneys play a role in regulating blood pressure by absorbing salts and water and removing wastes. Hormones secreted by the adrenal cortex cause the kidney to keep or let go of any salt

and water. This has an influence on blood volume and consequently on blood pressure.

• What is the main idea of the passage?
• Which statement is not a detail from the passage?
• Baroreceptors are rigid and static nerve endings that are contained along the arterial walls

and send out messages along the nerve pathway.

• Chemoreceptors are located along the walls of the arteries and monitor changes in oxygen

level.

• The kidneys play a role in regulating blood pressure by absorbing salts and water.
• The heart is the body's pump, which regulates the flow of vitally needed oxygen to cells of

the body.

• What is the meaning of the word evolved in the first paragraph?
• What is the writer's primary purpose in writing this essay?
• What is the best summary of this passage?

6.What is a major difference in the way baroreceptors and chemoreceptors work from the way the kidneys work?

• Baroreceptors and chemoreceptors both work within the wall of the arteries sending out

impulses to raise or lower blood pressure, whereas the kidneys help control blood volume.

• Baroreceptors and chemoreceptors both work to help maintain blood volume, whereas the

kidneys take care of salts, water, and waste removal.

• Baroreceptors and chemoreceptors must work together to control blood pressure, whereas

the kidneys work with the adrenal cortex.

• Baroreceptors and chemoreceptors are both located near the adrenal cortex, whereas the

kidneys are located near the heart.

Answer:

• Blood pressure can be regulated through baroreceptors, chemoreceptors, and the kidneys.

• Baroreceptors are rigid and static nerve endings that are contained along the arterial walls and

send out messages along the nerve pathway.

• To gradually develop

• To inform the reader how the cardiovascular system regulates blood pressure

• There are several systems to maintain the natural functions and processes of the body. One system

is the cardiovascular system, which regulates blood pressure through baroreceptors, chemoreceptors, and the kidneys.

6.

• Baroreceptors and chemoreceptors both work within the wall of the arteries sending out impulses to

raise or lower blood pressure, whereas the kidneys help control blood volume.

Question 3: Purpose

Answer:

The reason for reading or writing, such as entertain, inform, analyze, or persuade.

Question 4: "Example Context Clue"

Answer:

When the author gives examples that clearly help the reader understand the meaning of the unknown word.

Question 5: Antonym Context Clue

Answer:

When the author gives a word that means the opposite of the unknown word.

Question 6: Trees

Trees are as queer in picking out places to live and in their habits of growth as are the peoples of the various races which inhabit the world. Some trees do best in the icy northland. They become weak and die when brought to warm climates. Others that are accustomed to tropical weather fail to make further growth when exposed to extreme cold. The appearance of Jack Frost means death to most of the trees that come from near the equator. Even on the opposite slopes of the same mountain the types of trees are often very different. Trees that do well on the north side require plenty of moisture and cool weather. Those that prosper on south exposures are equipped to resist late and early frosts as well as very hot sunshine. The moisture needs of different trees are as remarkable as their likes and dislikes for warmth and cold. Some trees attain large size in a swampy country. Trees of the same kind will become stunted in sections where dry weather persists.In some parts of the United States forestry experts can tell where they are by the local tree growth. For example, in the extreme northern districts the spruce and the balsam fir are native.As one travels farther south these give way to little Jack pine and aspen trees. Next come the stately forests of white and Norway pine. Sometimes a few slow-growing hemlock trees appear in the colder sections. If one continues his journey toward the equator he will next pass through forests of broad-leaved trees. They will include oak, maple, beech, chestnut, hickory, and sycamore.

In Kentucky, which is a centre of the broad-leaved belt, there are several hundred different varieties of trees. Farther south, the cone-bearing species prevail. They are followed in the march toward the Gulf of Mexico by the tropical trees of southern Florida. If one journeys west from the Mississippi River across the Great Plains he finally will come to the Rocky Mountains, where evergreen trees predominate. If oak, maple, poplar, or other broad-leaved trees grow in that region, they occur in scattered stands. In the eastern forests the trees are close together.They form a leafy canopy overhead. In the forests of the Rockies the evergreens stand some distance apart so that their tops do not touch. As a result, these Western forests do not shade the ground as well as those in the east. This causes the soils of these forests to be much drier, and also increases the danger from fire.The forests of western Washington and Oregon, unlike most timberlands of the Rocky Mountain Region, are as dense as any forests in the world. Even at midday it is as dark as twilight in these forests. The trees are gigantic. They tower 150 to 300 feet above the ground. Their trunks often are 6 feet or larger in diameter. They make the trees of the eastern forests look stunted. They are excelled in size only by the mammoth redwood trees of northern California and the giant Sequoias of the southern Sierras. The trees found in the United States are beautiful. These trees are admired and loved by many around the world.
