Question: Article: Counterfeit ( ) medicines are a widespread problem in developing countries. Like other counterfeits, they look like real products. But counterfeit drugs may contain too little or none of the active ingredients of the real thing. People do not get the medicine they need. And in some cases counterfeits cause death. Twenty children in Bangladesh died last year after being given acetaminophen . 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 W.H.O. estimates that up to thirty percent of medicines on sale in many of those countries are counterfeit. The problem is less widespread among industrialized countries. The W.H.O. 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 on their products as a security device.

Question: Article: "Ten years ago I could never have imagined I'd be doing this,"says Greg Pal,33,a former software executive. "I mean ,this is essentially agriculture ,right? But the people I talk to, especially the ones coming out of business school , think this is the one hot area everyone wants to get into ." He means bugs. To be more accurate, the genetic change of bugs---very, very small ones---so that when they feed on agricultural waste such as woodchip or wheat straw ,they do something extraordinary . They excrete crude oil. Unbelievably ,this is not science fiction .Mr. Pal holds up a small cup of bug excretion that could ,in theory ,be poured into the tank of the big Lexus SUX next to us .Not that Mr. Pal was willing to risk it just yet .He gives it a month before the first vehicle is filled up with what he calls "renewable petroleum ".After that ,he smiles ,"It's a brave new world." Mr. Pal is a senior director of LS9,one of several companies in or near Silicon Valley.The company is not interested in using corn as material ,given the much-advertised problems created by using food crops for fuel .Instead ,different types of agricultural waste will be used according to whatever makes sense for the local climate and economy :wheat straw in California ,for example ,or woodchip in the south. Are Americans ready to be putting genetically changed bug excretion in their cars? "It's not the same as with food,"Mr. Pal say ."We are putting these bacteria in a very isolated container. Their entire universe is in that tank .When we've done with them .they are destroyed." " Besides ",he says ,"there is greater good being served."" I have two children, and climate change is something that they are going to face .The energy crisis is something that they are going to face .We have a collective responsibility to do this."

Question: Article: Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year Canadian scientist Geoge Kell proved the English physicist was right. Dr Kell filled one open bowl with cold water. He filled another with warm water. He put both bowls to the same low temperature. The warm water froze first. The lack of covers on the bowls was the secret . Some of the warm water changed into vapor. It evaporated into the air. This meant that less of the warm water was left to freeze. And so the warm water froze faster than the cold water.
Question: Sir Francis Bacon was _ .
Options: (A) an American scientist (B) a Canadian scientist (C) a French scientist (D) an English scientist
