问题    Jarden Zinc Products, a large zinc plant a few miles outside Greeneville, Tennessee, has a special claim. Since 1982, it has been the only supplier of penny blanks for the U. S. Mint (铸币厂). It’ s a good business for Jarden—since 2000, the company has earned more than $ 800 million. But it may not be a good deal for the U. S.
   The value of the penny has been dropping for years. In 2006, it began to cost more than a penny to make a penny. It now costs 2 ￠ to produce a 1 ￠ coin. Many countries have stopped using pennies. Is it time for the U. S. to do the same?
   Jarden and the zinc industry are fighting to keep the penny. Since 2006, Jarden has given $1.2 million to Americans for Common Cents (ACC). The group’ s mission is to keep the penny in use. Mark Weller is ACC’ s executive director. He argues that there are three main reasons for keeping the penny: Without it, we would become more reliant on the five-cent coin, which also has problems: charities that depend on penny drives would not be able to raise as much money: and a 2012 survey shows that 67% of Americans want to keep the penny. Many people surveyed said they feared they would end up paying more for products.
   Many experts disagree with ACC. They point to the dozens of countries that have gotten rid of their lowest-value coins without raising prices for consumers. And charities don’ t seem too concerned either.
   President Barack Obama says the mint could explore using cheaper metals to make pennies. Steel is less expensive than zinc. Pennies are 97. 5% zinc and 2. 5% copper. But no matter what it is made of, the penny’ s days may be numbered. Most in-store purchases are now made with credit cards, not cash. Is it time for a change?
The penny coin is mainly made of______.
选项 A、copper
B、steel
C、iron
D、zinc
答案D
解析 根据最后一段第三句“Pennies are 97．5％zinc and 2．5％copper．”可知，1分硬币是由97．5％的锌和2．5％的铜制造而成。故选D。
