Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: The surprising experiment I am about to describe proves that air is all around you and that it presses down upon you. Air pressure is a powerful force. When you swim underwater, you can feel water pushing on your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth's surface. The following experiment is an easy one that you can do at home. But make sure that you are supervised , because you will need to use matches. Now for the experiment. What you need * hard-boiled egg without the shell * A bottle with a neck slightly smaller than the egg * A piece of paper * A match Method 1) Check that the egg will sit firmly on the neck of the bottle. 2) Tear the paper into pieces and put them into the bottle. 3) Light the paper by dropping a burning match into the bottle. 4) Quickly sit the egg on the neck of the bottle. Result Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches. Why it happened? As the paper burns, it needs oxygen and uses up the oxygen (air) in the bottle. The egg acts as a scale in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air presses against the egg, and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on us. Options: A The bottle could break. B You need to light the paper with a match. C The egg needs to be shelled . D The egg has to be perfectly placed on the neck of the bottle. Answer: B You need to light the paper with a match.

Answer: Why is there the need to take care when you are doing the experiment?

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Beach volleyball is one of those sports that can be an exciting game to play and watch, or, can just be about some friends getting together to have a great time. It's really easy, and all you need is sand, a net and a group of people, of any age or fitness level, who want to have fun. Beach volleyball can be played with as few as two people on each team, making a total of four people. However, if you are less skilled and experienced in the game, it will be easier to play with a larger team. The more players you have, the less ground each person will be responsible for covering and the more time they will have to recover in between shots. If you only have a few players, each of you will get quite a workout running for the ball after each volley. If you are looking for that relaxing, fun, low-key experience, choose larger teams. Beach volleyball is similar to regular volleyball in its rules. However, even experienced volleyball players do not realize how much more difficult it is to run and jump on sand. Since it is harder to move quickly on sand than a hard ground, play will be much slower than regular volleyball on a playground. When a player trains for beach volleyball, he will focus on building lower body strength as well as upper body. While he needs to be able to hit the ball with a great deal of power and accuracy , strengthening his legs is extremely important. Whether you are in it for the competition, or just to have a great time with your friends, beach volleyball can be very exciting and fun. You may even start out with friends and fall in love with the sport. Options: A it is not an easy job to move on sand B it is a workout running for the ball C it is usually a larger team D the beach volleyball is heavier Answer: A it is not an easy job to move on sand Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: FRIDAY, Aug. 3 (Health Day News) -- Middle school students who are physically fit are likely to score higher on standardized tests measuring reading and math abilities, a new study has found. And, the average scores went up in connection with levels of fitness, the findings showed. "The more physically fit kids were, the higher their scores," said the study's lead author, Trent Petrie, director of the Center for Sport Psychology at the University of North Texas in Denton. "Parents should encourage their kids to be physically active. There are some real cognitive and academic benefits that come from physical fitness", Petrie said. Results of the study are scheduled to be presented Friday at the annual meeting of the American Psychological Association in Orlando, Fla. The study included more than 1,200 middle school students from five schools in a suburban area of Texas, with 561 boys and 650 girls. About 57 percent of the children were white, and nearly one-quarter were Mexican American. Nine percent were black and about 2 percent were of Asian descent. The school district provided the researchers with information on the children's race, age, grade level and whether they qualified for the free school lunch program, which was an indicator of the family's socioeconomic status. The schools also provided scores to the tests, which were given between one and four months after the researchers had assessed the children's levels of fitness. Fitness tests were administered during physical education classes to determine the youngsters' heart and lung health (cardiorespiratory fitness), as well as their body mass index (BMI), an indicator of how much body fat a person has. The children also filled out questionnaires that helped the researchers determine factors such as self-esteem and social support. After accounting for factors such as age, sex, family income and self-esteem, the researchers found that for both boys and girls, higher levels of heart and lung health predicted better scores on both the math and reading...
