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." Question: Where did the 30 sparrows spend their summer? Options: A: Princeton B: Washington C: Alaska D: In the southwesternUnited States

Read the article and select the best answer. Article: There are many traditions around the holidays. "Holiday traditions" are things that people do every year during a holiday such as Christmas or Thanksgiving. At Christmas, for example, many people put up a Christmas tree or Christmas lights. These are Christmas traditions that have been going on for many years. But there is a "new" Christmas tradition that has become very popular: _ , a TV channel that shows nothing but a large log fire, blazing in a fireplace. People put it on their TV and it makes them feel like they are watching and listening to a crackling fire. It makes them feel calm and comfortable. The origin dates back to 1986 in Canada. At that time, not very many people knew about it or watched the channel. Today, more than three million people watch the firelog channel during the winter holiday season. That year, the firelog channel was created to give the workers in the company that is now called Shaw Cable, a break at Christmas. By running the firelog during the holidays, everyone could go home for a few days and enjoy a bit of time off. At that time, it was only broadcast to people in Edmonton but today it reaches people across Canada and beyond. This year, the Shaw firelog was updated. It is pretty high tech. Although it's still really just a fire log that has been filmed, it has its own Twitter account (@ShawFireLog), its own Facebook page and it even has a computer App so you can see the burning log on a smartphone or a tablet. The Shaw firelog will burn until Jan. 5 on Shaw Cable, channel 222. Question: For what purpose was the TV firelog created? Options: A: To attract more people to watch their programs. B: To make people feel calm and comfortable by watching a crackling fire. C: To give the people working at the company a few days off at Christmas. D: To create more new traditions for people to celebrate Christmas.
