Article: A listener from Brazil recently wrote to us asking for some advice. He's planning a trip to the United States, and wanted to know about the best places to travel in America. Today, we tell about the most popular places to visit in the country, and hear about what makes them so appealing. Each of the 50 states in America has interesting things to offer visitors, but some are more popular than others.

Visitors to Los Angeles, California can see the Hollywood Walk of Fame or shop the stores on Rodeo Drive where they may see a star or two. The Grand Canyon in Arizona appeals to hikers, climbers and nature lovers, as does Yellowstone National Park in Wyoming. Trip Advisor is a website where people can write reviews about their travel experiences. There are also ratings for hotels, restaurants, and places people have visited around the world. Every year, Trip Advisor makes a list of the top 25 cities to visit in the United States. The results are based on the opinions of visitors to the website. America's major cities are still the most popular destinations for visitors. This is probably because of the good quality of services they provide tourists.

Article: Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all, you probably sing or whistle when you are happy. Some scientists believe that birds do sing some of the time just because they are happy. However, they sing most of the time for a very different reason. Their singing is actually a warning to other birds to stay out of their territory. Do you know what a 'territory' is? A territory is an area that an animal, usually the male, claims as its own. Only he and his family are welcome there. No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger enter your territory and threaten you, you may shout. Probably this is enough to frighten him away. If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting season. So he is screaming all the time, whether he can see an outsider or not. This screaming is what we call a bird's song, and it is usually enough to keep an outsider away. Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs. You can see that birds have a language of their own. Most of it has something to do with attracting mates and setting up territories. Question: How does the writer explain bird's singing? Yes or no, is the answer "By comparing birds with human beings."?
Yes

Q: Article: Once in a blue moon, there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't expect it to be blue - the name has nothing to do with the color of our closest celestial neighbor. A full moon occurred on December 2. It will appear again on Thursday in time for the New Year's countdown. The New Year's Eve blue moon will be visible in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up until New Year's Day, making January a blue moon month for them. A full moon occurs every 29.5 days, and most years have 12. On average, an extra full moon in a month - a blue moon - occurs every 2.5 years. The last time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't come again until 2028. "Blue moons have no astronomical significance," said Greg Laughlin, an astronomer at the University of California. "'Blue moon' is just a name in the same sense as a 'hunter's moon'(a full moon in octorber) or a 'harvest moon,'" Laughlin said in an e-mail. The popular definition of blue moon came about after a writer for Sky & Telescope magazine in 1946 misinterpreted the Maine Farmer's Almanac and labeled a blue moon as the second full moon in a month. In fact, the almanac defined a blue moon as the third full moon in a season with four full moons. Question: What's the color of blue moon? Yes or no, is the answer "golden"?
A: No

Article: The Venice Carnival is the largest and the most important Venetian festival. It is a festival that celebrates the passage from winter to spring, a time when seemingly anything is possible, including the illusion that the people at the bottom become the most powerful by wearing masks on their faces. The Venice Carnival could date back to 1296. It was confirmed on the day before Lent, a public holiday, but it had no direct religious connection at that time. However, the participants were not allowed to wear masks around the city at night; men could not enter convents if they pretended to be women, and celebrations within the convents were strictly forbidden. People who broke the rules could be put into prison. The laws were not relaxed until the late 17thcentury, when the carnival-goers were allowed to wear masks throughout the carnival. Participants would wear a white mask in old days, while costumes have become even wilder today. St. Mark's Square is the center for the carnival, while Campo San Polo and Sestiere are two other popular places where events take place. Most of the events are free, along with several unusual masked balls for which visitors will have to buy tickets in advance. The 2012 Venetian Carnival was celebrated from February 11 to 21. There were the liveliest celebrations of parties, performances, show, music, dances, dinner sets along streets, and hotels. It attracted a great number of visitors around the world. Many travelers booked Venice hotels and prepared costumes and masks well ahead of time so that they couldn't be made fun of by local people. Question: From this passage we learn that in today's carnival _ . Yes or no, is the answer "not all events are free"?
No
