IDENTIFY THE MAIN IDEA

Being a clown isn't all fun and games. Rodeo clowns expose themselves to great danger every time they perform. When cowboys dismount or bulls buck them off, rodeo clowns jump in front of the bulls and motion wildly to get their attention. In this way rodeo clowns provide an alternate target, and in doing so protect the rider. Of course, this is a very dangerous thing to do. So you see, sometimes clowning around can be serious business.

• Sometimes clowns can mean serious bussiness.

• Rodeo clowns protect cowboys by putting themselves in danger.

• Cowboys and Rodeo Clowns are constantly in danger.

• A Rodeo bull's attention is easily caught by Rodeo clowns.

Sometime in December of 1891, Dr. James Naismith was teaching gym at the YMCA College in Springfield, Massachusetts. It was raining, and Dr. Naismith was trying to keep his students active. He wanted them playing a rough game that would keep them moving. He didn't like a few ideas that were too rough. Then Naismith had his breakthrough. He wrote out the rules for a game with peach baskets fixed to ten-foot elevated tracks. Naismith's students played against one another, passing the ball around and shooting it into the peach baskets. Dribbling wasn't a part of the original game. Also it took a while to realize that the game would run more smoothly if the bottoms of the baskets were removed. But this game grew to be one of the most popular sports in America today. Can you guess which one?

• The most popular sport in America

• Dr. James Naismith's career in teaching

• The invention of Basketball

IDENTIFY THE MAIN IDEA

You might think that all automobile fuels are the same, but they aren't. Automobiles can run on one of three types of fuel: gasoline, diesel, and biodiesel. All these fuels are burned inside of the engine, which creates the heat and energy that is used to power the car. But there are important differences between these fuels. Gasoline and diesel are more common than biodiesel. But each burns differently. Diesel fuel is heavier and less flammable than gasoline, so it has to be compressed before it will burn. Gasoline may be lighter than diesel, but both fuels are made from crude oil. On the other hand, biodiesel fuel is made from vegetables. Both biodiesel and diesel fuels must be burned in diesel engines, which only use diesel fuel. If gasoline is pumped into a diesel engine, it will have to be pumped out. These fuels may look pretty similar at the gas station, but remember that there are important differences between them or it may cost you.

• Which fuel is best to use for your car

• Gasoline, diesel, and biodiesels area all fuels, but they have important differences in how they are made and used.

• The benefits of biodiesel

• How fuels change the way we drive
