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. Washington, D.C. is famous for its historical places, like the White House and the Lincoln Memorial. 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.

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: There is just one four-legged animal that can walk two hundred miles without stopping once to rest. It would take a person two days and two nights to walk this far, and only one man has ever done it without stopping. What amazing animal has such endurance ? The camel! The camel is well known for something else, too. It can cross an entire desert without a single drink of water. Its body is built in a special way to help it store water and food. A person has just one stomach, but a camel has quite a few. Within each stomach are layers and layers of cells. These cells are like tiny water balloons, storing liquids until the camel needs them. When the camel drinks, the cells grow larger and larger. For a whole week, they can keep the animal's thirst away by sending water to all parts of its body. Have you ever wondered why the camel has a hump ? The hump is a storage place for fat. Because it has this storage area, the camel does not need to eat very often. When the animal needs energy, the layers of fat serve as fuel to keep it going on the long, hot days in the burning sun. The camel has another gift that makes it well suited to arid regions. This gift is its amazing nose. A camel can smell a water hole from miles away! When a camel moves, it sways from side to side like a ship on a wavy ocean. Because of this swaying motion, the camel has been called the "ship of the desert". Options: A It has several stomachs B The nose of a camel is special. C The camel has a hump which can store fat. D It has a swaying motion. Answer: D It has a swaying motion. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: 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. Options: A December, 2009 B November, 2009 C January, 2010 D February, 2010 Answer: C January, 2010 Question:

Answer: If you are in China, in which month can you see the blue moon?

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: A new American report says water-related problems will likely increase tensions around the world in the next ten years. These problems include water shortages, poor water quality and floods. The problems will increase the risk of failure of governments. However, countries are unlikely to go to war over water. But the real question is that some governments may use water as a weapon to pressure others ten years later. The report looks at possible effects of water problems on the United States national security interests over the next thirty years. It says the areas that will be most affected by water problems are North Africa, the Middle East and South Asia. The United States Secretary of State Hillary Clinton says, "Reliable water resources are essential for feeding the hungry, running industries and creating energy. Certainly they are central when we think about how climate changes will affect future generations." The report also predicts an increased demand for American assistance and expert help to solve those problems. That demand for help could create opportunities for leadership and influence. Water shortages, poor water quality, and floods are unlikely to result in state failure. But these could combine with poverty, social tensions, environmental problems, poor leadership and weak governments to produce social disorder. And that combination could cause state failure. The report predicts that from now through 2040 water shortages and pollution probably will harm the economic performance of important trading partners. During the next ten years the loss of groundwater supplies in some agricultural areas will create a risk to national and global food markets. These shortages will be a result of poor management. Agriculture uses about seventy percent of the world's freshwater. The report says technology that reduces the amount of water needed to grow crops will offer the best way to fight against water shortages. Options: A People would suffer from more floods. B Water would be used as a kind of weapon. C Water problems would lead to war in the future. D Floods would make water shortages more serious. Answer: B Water would be used as a kind of weapon. Question:

A:
What is the real concern of the report?
