Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Millions of people die of hunger in southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely said no. "We don't know whether the food is safe," said Zambia's commerce, Trade and Industry Minister Dipak Patel. His worries are shared by countries around the world that are in two minds about America's genetically modified(GM,)crops.Just last week, EU member nations were discussing whether or not to import GM sweet corn from the US. Ever since people started farming, they have tried to crossbreed plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other. But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature. This means they can make crops more productive and resistant to disease by adding genes from other species.They can also create food with special characteristics, such as "golden rice", which is enriched with vitamin A. But many people believe GM foods are a health risk. At the moment, the official argument is that GM foods "are not likely to present risks for human health". But there are still many questions to be answered as the foods are produced in different ways. Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops. People in China are also getting worried about GM foods. More than 70 percent of the country's soybean oil is produced from imported GM soybeans. Meanwhile, an investigation last November found that 12 of 60 famous foods sold across the country were GM products. The government has begun to introduce a marking system for GM goods so that people can choose whether or not to eat them. Options: A GM foods are harmful to people's health B GM food is no better than naturally produced foods C only related plans could be crossed with each other D GM techniques can increase the production of crops Answer: D GM techniques can increase the production of crops Question:

A: It has been proved that _ .

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Even bird brains can get to know an entire continent ----- but it takes them a year of migration to do so, suggests a Princeton research team. The scientists have shown that migration adult sparrows can find their way to their winter nesting grounds even after being thrown off course by thousands of miles. The team first brought 30 sparrows to Princeton from northern Washington State, where the birds had been in the process of migrating southward from their summer breeding grounds inprefix = st1 /Alaska. Half the birds were juveniles of about three months in age that had never migrated before, while the other half were adults that had made the round trip to their wintering site in the south-western United States at least once. After the birds were released, they attempted to resume their migration, but both age group grew disoriented quickly. "All the birds scattered at first," Wikelski said. "It was clear that they were turned around for a couple of days. But while the adults eventually realized they had to head southwest, the younger birds resumed flying straight southward as though they were still in Washington." "The adults," said team member Richard Holland, "recovered their bearings because they possess something the younger birds do not, which is an internal map." "These birds need two things to know where they are and migrate effectively: a 'map' and a 'compass'," saidHolland, a postdoctoral research associate in Wikelski's lab. "What we've found is that juveniles use their compass, but the adults also use their map." Hollandsaid, "The birds do not lose the compass as they age, but somehow develop the map, eventually applying both tools to keep on track during migratory flights. Scientists already have determined that the compass is based on the sun or the magnetic field, but where the map comes from remains a mystery----one that the team will be exploring in coming years." Options: A Princeton B Washington C Alaska D In the southwesternUnited States Answer: C Alaska Question:
