问题    Counterfeit medicines are a widespread problem in developing countries. Like other counterfeits, they look like real products. But counterfeit drugs may contain too much, too little or none of the active ingredients of the real thing.
   People do not get the medicine they need. And in some cases the counterfeits cause death. Twenty children in Bangladesh died last year after being given acetaminophen (醋氨酚). The medications contained ingredients that looked, smelled and tasted like the real thing. The medicine was produced by a local drug company that used a dangerous substitute to save money.
   The problem of counterfeit medicines is especially serious in Africa, Asia and Latin America. The WHO estimates that up to thirty percent of medicines on sale in many of those countries are counterfeits. The problem is less widespread among industrialized countries. The WHO says counterfeits make up less than one percent of the illegal drug market in countries like the United States, Canada, Japan, and New Zealand. But the agency also says as much as fifty percent of the medicine sold on the Internet is counterfeit.
   Much is being done to fight counterfeit drugs. Several companies are developing ways to make counterfeits easier to identify. And there are existing methods, like a machine that can quickly identify chemicals in pills to confirm if the pills are real. Other ideas include things like special tracking codes for drug packages. People could send a text message with the code and get a message back, which proves that what they bought is listed in a database. Some drug makers and other companies put three-dimensional images called holograms (全息图) on their products as a security device.
What is the main idea of the last paragraph?
选项 A、It shows the danger of counterfeit drugs.
B、Special tracking codes for drug packages are used to identify counterfeits.
C、Some measures are being taken to fight counterfeit drugs.
D、It reveals the reasons why counterfeit drugs are widespread.
答案C
解析 根据第四段的主题句，即第一句“Much is being done to fight counterfeit drugs．”可知，为了和假药作斗争，人们已经采取了很多措施。且接下来列举了一些具体的措施。故选C。
