问题 单项选择题

二元经济理论看重“劳动力无限供给”,然而,在有些国家并不是素质高、有效率、有能力的劳动力的供给,比如,拉丁美洲的人由于受到天主教观念的影响,厌恶劳动而喜欢玩乐,许多地方成了“懒汉”的无限供给;还有一些国家是自杀爆炸者的无限供给。像经济学家所设想的那种勤奋的劳动力无限供给的例子,在这个世界上并不是普遍的。并且,即使有无限供给,谁来吸收这些劳动力,也是一个问题。 以下理解错误的是( )。

A.“劳动力无限供给”要求素质高、有效率、有能力的劳动力

Many people say pennies are not worth saving. After all, a penny is only worth a cent. But one unusual penny turned out to be worth a lot more when a coin collector paid $1.7 million for it earlier this month.

The coin is one of a kind. It is the only penny that the Denver mint(铸币厂) made out of copper, instead of steel, in 1943. Because it is unique, it is also very valuable. No penny has ever sold for so much money.

The Changing Penny

The Lincoln penny first appeared in 1909. For 34 years, the one-cent coin was made out of copper. Then, in 1943, the penny changed. World War II was going on, and copper was needed for equipment. So for one year, pennies were made out of steel instead. At least most of them were.

Only a few coins were made out of unused copper. There are three main mints, or places where coins are made, in the United States. Of the known copper pennies from 1943, twelve were made in the Philadephia mint, and five were made in the San Francisco mint. Only one was made in the Denver mint.

Nobody knows for sure why a copper penny was made at the Denver mint in 1943, coin dealers Andy Skrabalak told Time for Kids. “There is a rumor that a mint employee made the coin in the middle of the night.”

A Special Set

The coin collector who bought the $1.7 million penny wants to remain unknown. But the reason for the trade is known. He already had two copper pennies from 1943 – one from the San Francisco mint and one from the Philadephia mint. To complete the set, he needed the Denver penny. The three coins will go on display at a coin exhibition in Tampa, Florida.

The collector who sold the penny is also keeping his name a secret. It took four years to convince him to give up the rare coin. Now that he has finally donating all of the money to charity.
