Read the following article and select the best answer. Article: In America, square dancing has been the most popular form of folk dancing since the early days. In early times, when men and women worked in groups to build a barn or harvest crops, they danced when the work was done. The music came from the violin for the most part, but if there was no one to play a musical instrument, clapping was used to produce the rhythm to which people dance. The early settlers danced in a store, in a barn, or in a farm kitchen. A square is formed by four couples who stand facing the centre of the square. Each couple stand on one side of the square, the boy on the left and the girl on the right. The caller is an important part of the dance, since he tells the dancers which steps to do. If the dancers do not know the steps, he teaches them. It takes time to learn to be a good caller, and good callers are always in demand . These are the names of some of the steps the dancers do: Form a square; Circle; Honour your partner; Swing your partner; Form a star. There are many more. As the callers tell the dancers what to do next, they move to form the pattern he calls. Large or small numbers of people can dance at one time. Sometimes 800 or 1,000 people may be dancing at the same time. Or there may be only one square of eight people. Special clothes are worn by some when dancing. This makes the dance more colourful to watch. The special clothes are different from place to place. Women often wear full skirts of various colours with a pretty blouse. Men have coloured shirts and western trousers that they wear only when square dancing. In some country areas, everyone wears his best clothes. Today in some parts of the United States you will find some schools, clubs, or groups square dancing for fun. Question: If 800 people dance at the same time,how many squares can be formed? - 200 squares. - 100 squares. - 400 squares. - One big square.
**Answer**
100 squares.

Read the following article and select the best answer. Article: A three-year independent investigation into the September 11, 2001 attack on the Pentagon has _ new eyewitness evidence which, according to the Southern California-based researchers who conducted the investigation conclusively (and unfortunately), establishes as a historical fact that the violence which took place in Arlington that day was not the result of a surprise attack by suicide hijackers, but rather a military black operation involving a carefully planned and skillfully executed deception." A CNN Reporter at the scene states that there is no evidence that a 757 hit the Pentagon. What hit the Pentagon? A Boeing 757 loaded with passengers and fuel right? Who was on Flight 757? According to the Flight Information there were No Arabs on it. That makes me wonder if Flight 757 actually existed at all. From the pictures and the videos, people can find that there are several doubtful points that need to be taken into consideration, for example the marker line on the grass in the satellite and ground pictures, the different colors of the smoke, the hole which the plane impacted, and the standing pylons . Also, from the comparison of the different pictures, people can find some other strange points. For example, the gear is not the matching one. The wreckage of the plane is not the one from the American Airlines. The glass on the pavement of the pole is another doubtful point. The last thing that need considering is about the collapse. One of the gif video shows the plane impacting the Pentagon. The only problem with this video footage is that it has been altered and can not be fully trusted. These crash photos and videos shown here clearly have been doctored and don't even match the physics of what happened. So where is the real video? It leaves me many questions. Is this a missile? It is a real enigma. Question: Where can you possibly read this article? - In a newspaper. - In a book. - On a website. - In a magazine.
**Answer**
On a website.

Read the following article and select the best answer. Article: As wild animal lovers are not content with watching tigers and gorillas during the day, a growing number of zoos in the US are offering a more thrilling after-dark experience -- overnight stays. The Philadelphia Zoo is America's first zoo and home to more than 1,300 animals. It has been running its Roars and Snores Overnight Programs for about 20 years. The most popular theme program is the Night Flight Overnight Program where children aged 5 to 12 sleep in the zoo's tree house. The overnight stays are not only popular with young children. Most overnight stays include a night tour during which youngsters experience the mysterious sights and unusual sounds of the zoo. A midnight snack and breakfast are also served. "It is a unique experience to be at the zoo without the crowds and additional noise," explained Patterson, of the Denver Zoo, which has been running its Bunk with the Beasts program since 1998. With nearly 4,000 animals and 700 species the zoo attracts more than 1.8 million visitors a year. "The things you hear and see in the zoo are completely different," said Patterson. On Denver's two-hour tours, night vision scopes are provided so guests can see nocturnal animals such as owls, and indoor educational games increase the learning experience. Patterson said parents tend to be more worried about leaving their children than the children themselves. They have rarely had to call up a parent in the middle of the night. "They love it," Patterson said about the children. "For many, it's their first overnight stay away from home. They are so excited that by the end of the day they are so tired that they have no opportunity to worry." "Guests at the new overnight program at the Queens Zoo make breakfast treats for animals, and watch the keepers feed them to the animals," said Education Curator Tome Hurtubise. The growing popularity of overnight programs has caused zoos that only serve day-time visitors to think again. The Queens Zoo, which started their program this year, is so pleased with its success...
