(1) Do you spend your days feeling slow and sluggish, still sleepy hours after getting out of bed? (2) If you answered “yes” to that question, you need more exercise, not more sleep. (3) The best way to get rid of that tired feeling that never seems to go away is to begin exercising as soon as you wake up. Now, you don’t have to do a weight lifting routine, go on a 15 mile bicycle ride, or do hundreds of sit-ups. All you have to do is get moving.

Wolverines are medium sized mammals. They weigh no more than 50 lbs. Yet they have earned their reputation for ferocity by killing prey many times their size. But why do they get in so many fights? The reason why wolverines have so many conflicts with other animals (including wolves, cougars, and even bears) is probably because of the wolverine's preferred hunting style. Rather than chasing down or tricking its prey like most hunters, the wolverine prefers to take its meals directly from other hunters. So while a polar bear or a lone wolf might be enjoying a hard earned carcass, a hungry wolverine may try to take his lunch. As you might imagine, this style of hunting get the wolverine in plenty of fights. What is the CENTRAL IDEA in the above paragraph?

Wolverines have a aggressive hunting style.

Wolverines are medium sized animals who get very hungry.

Despite their size, Wolverines are ferocious animals.

Wolverines get into many fights.

Exercise increases your energy.

Everyone should exercise daily.

Exercise is easier than it looks.

Exercise makes you live longer.

Most people want to think that they are in control of their pets. However, a study by Karen McComb at the University of Sussex found that cat owners are controlled by their cats. Cat owners probably won’t have too much trouble believing this. Cats make a fairly loud noise by mixing a purr with a cry. The sound seems to be less annoying to humans than straight meowing. Using this sound, cats tell humans when they want to eat and when they want the door opened. The purr part of the sound keeps humans from becoming too annoyed, so the cat gets exactly what he or she wants. Which sentence from the paragraph SUPPORTS the central idea that CATS HAVE A SMART WAY OF GETTING WHAT THEY WANT?

"The purr part of the sound keeps humans from becoming too annoyed."

"Most people want to think that they are in control of their pets."

"Cat owners probably won't have too much trouble believing this."

"Cats make a fairly loud noise by mixing a purr with a cry."

Most children have an interest in learning to play a musical instrument at one point or another during their growing-up years. Parents need to take advantage of that urge to play when it appears. Some very small children become intrigued with music because they see their parents or their older siblings play. The Suzuki method of instruction capitalizes on that early willingness to learn by involving the parent and the child in the child’s instructions. Elementary-aged youngsters often are exposed to stringed instruments or band instruments in their school music classes. Because kids like to do what other kids do, parents who are not musicians themselves can take advantage of both instruction and enthusiasm. It is at the middle school level, however, that peer pressure can really work to the benefit of parents who want to hear the sound of music around the house.
What is the Main Idea?

most children have an interest in learning to play a musical instrument during their growing-up years.

some very small children become intrigued with music because they see their parents or siblings play

at various points, parents can take advantage of their children’s desire to play a musical instrument.

middle-school children take delight at selecting and learning to play an instrument along with their friends.

The land that was bought was rich in timber, minerals, and natural resources of many kinds. Finally, the cost of the transaction was unbelievably low; the total of $15 million amounted to about four cents an acre.

There is some evidence that colors affect you physiologically. For example, when subjects are exposed to red light respiratory movements increase; exposure to blue decreases respiratory movements. Similarly, eye blinks increase in frequency when eyes are exposed to red light and decrease when exposed to blue. This seems consistent with intuitive feelings about blue being more soothing and red being more arousing. After changing a school’s walls from orange and white to blue, the blood pressure of the students decreased while their academic performance improved
