I'm taking a test and have to guess the right answer to the question after the article. Article: If you're like most kids, you've probably made more than a few paper airplanes in your day. But how many kids can say their paper airplanes have been built life-size and then flown? At least one: 12-year-old Arturo Veldenegro of Tucson, Arizona, who won the Pima Air& Space Museum's first annual Great Paper Airplane Project Fly-Off in March 2012. " The purpose of the competition is to inspire and draw kids' interest in science and flight," says Tim Vimmerstedt, director of the museum. About 150 kids entered the competition. The young designers learned about how airplanes fly and then set to work designing their own planes. Arturo designed and built his airplane. When hen was finished, he took his plane to the flight area and let it fly, outdistancing the other competitors in all age groups. At last, Arturo's airplane flew the farthest---more than 75 feet! As the winner, Arturo got to meet with a team of engineers, which took his design and made a bigger one. The new paper airplane might have been the largest one ever built! Arturo named his large paper airplane Arturo's Desert Eagle. Later a helicopter tried to lift the paper airplane over the Arizona desert, but it was unsuccessful. Engineers worked for eight hours to repair it for a second try. This time, the helicopter managed to raise it to 2700 feet and then set the plane free. Arturo watched as his plane flew through the sky at speeds of up to 98 miles per hour for 10 seconds before falling to pieces. "I felt happy but sad," Arturo says, " It flew really well, but it was sad to see it destroyed." But that wasn't the end of Arturo's Desert Eagle. The Pima Air & Space Museum collected the pieces of the broken plane and put them on show to inspire other young engineers to reach for the sky. Question: According to the text, the Great Paper Airplane Project Fly-Off competition _ Options: A: has been held many times B: can only be entered by kids C: is to choose the largest plane D: is held by a team of designers

I'm taking a test and have to guess the right answer to the question after the article. Article: Revealed to the world by the famous British explorer, Dr David Livingstone, in 1855, the Victoria Falls are one of Africa's best-known natural wonders. They form a natural border between Zimbabwe and Zambia . The falls are named after Queen Victoria by Livingstone. They were known to the native people in the 18th century as: "the smoke that thunders". The waterfall is formed as the two-kilometer-wide Zambezi River spills over the edge of its giant stone riverbed and falls into the gorge below. At their highest point, the Victoria Falls drop a distance of 108m, almost twice as far as the Niagara Falls. As much as 546 million cubic meters of water per minute falls over the edge from that height. Viewing the falls from the Zambian side means that visitors can follow a path that goes right up to the falls. The falls can also be viewed from the Boiling Pot, right in the depths of the gorge at the bottom of the falls. The 111-meter-high Victoria Falls Bridge, a railway crossing, is now a popular place for Bungee jumping. It can be crossed on foot for excellent views of the falls and the winding blue-green waters of the Zambezi River. It is also possible to see the falls from a plane. The area around the falls is a major game-viewing place. The best time to view the Victoria Falls is between December and July, when the water level is the highest.

I'm taking a test and have to guess the right answer to the question after the article. Article: Life in space will certainly take some getting used to!But the space station has been designed to keep the astronauts as comfortable as possible--the modules are roomy,bright,and kept at a constant 70 degrees Fahrenheit.It's important the crew members are comfortable because they'll be busy aboard the station.In a typical workday,crew members will spend 14 hours working and exercising,1.5 hours preparing and eating meals,and 8.5 hours sleeping.Here are some other fun facts about life aboard the station: Food Come mealtime,astronauts will have a special dining kitchen.Space food just keeps getting better--and more like food we enjoy here on Earth.In early space missions,astronauts could eat only freezedried food that didn't require any preparation.But the space station is equipped with water,microwave ovens,and refrigerators,allowing the folks on board to eat more "normal" types of food,including fruit,vegetables,and ice cream! Sleep Each crew member has a private room.With no gravity,they'll need to tie themselves to their beds,or they will float away!That might sound like a strange way to sleep,but astronauts from past space missions report that sleeping in space is actually pretty great! Exercise You might not think it,but exercise is even more important on the station than it is on Earth.There is not much gravity in space.Astronauts don't stand up,sit down or walk in space,so their muscles and bones don't have to work much--and this muscle and bone loss can be dangerous back on Earth.To fight this,astronauts on the station will exercise on bikes,rowing machines,and other equipment about two hours every day. Clothing Astronauts will have to wear special space suits while traveling aboard the U.S.shuttle or Russian rockets.But once they're safe inside the space station,crew members can wear regular clothing.Of course,a specially designed,pressurized space suit is required for space walks.It has to withstand flying pieces and protect the astronauts from dramatic temperature changes.It can range from 120... Question: The facts about life in space are all mentioned EXCEPT _ . Options: A: clothing B: entertainment C: sleep D: exercise
