People often refer to taxes in terms of their being much too high. In reality, they are probably even higher than you think, because in addition to the federal income tax we are now studying, there are many other Federal, State, and local taxes, including sales taxes, inheritance taxes, state income taxes, personal property taxes, real estate taxes, and others. These are just some of the most obvious ones.

Which statement best expresses the Central Idea?

• Taxes are much too high.

• We pay more taxes than we may realize.

• Inheritance taxes and real estate taxes are unfair.

• Some taxes are hidden.

The attitudes of Americans toward gambling are amazingly contradictory. You may find, for example, that horse racing is legal in your state, but that you cannot legally play poker for money on your front porch; bookies may be prosecuted by state law, but they are supposed to purchase a federal license nonetheless; one church condemns gambling, while another raises money by sponsoring Bingo games. Gambling laws are inconsistent from state to state or even from town to town and are very difficult to enforce.

Which statement below BEST expresses the main idea?

• Americans have negative attitudes toward gambling.

• Gambling laws are difficult to enforce.

• Gambling laws are inconsistent from community to community.

• Churches do not have uniform ideas about gambling.

A penny for your thoughts? If it’s a 1943 copper penny, it could be worth as much as fifty thousand dollars. In 1943, most pennies were made out of steel since copper was needed for World War II, so the 1943 copper penny is ultra-rare. Another rarity is the 1955 double die penny. These pennies were mistakenly double stamped, so they have overlapping dates and letters. If it’s uncirculated, it’d easily fetch $25,000 at an auction. Now that’s a pretty penny.

Which of these sentences BEST expresses the Central Idea?

• These pennies were mistakenly double stamped, so they have overlapping dates and letters.

• If it’s uncirculated, it’d easily fetch $25,000 at an auction.

• If it’s a 1943 copper penny, it could be worth as much as fifty thousand dollars.

What's that humming sound? Could it be the hummingbird, the only bird capable of backward flight? Hummingbirds have many unique flight habits that distinguish them from other birds. Most birds flap their wings up and down to fly, but the hummingbird moves its wings forward and backward very rapidly in a figure eight pattern. This allows the hummingbird to hover in position. They can also fly upside down and move about very rapidly. Other birds have to push off with their feet to begin flying and work their ways up to their top speeds. The hummingbird can both start flying at maximum speed and stop flying instantaneously. Once you've seen a hummingbird in flight, it's unlikely that you'll mistake them for another bird.
