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. The experiment is carried out to prove  _  .. A) water pushes on your body when you swim underwater B) the earth is surrounded by a layer of air called the atmosphere C) the pressure of air around us has a powerful force D) the air pressure is not equalized around us

Ques: The great white shark is the largest shark and is probably the most well-known and feared shark. The great white shark is gray or bluish above and white below. The largest Great Whites can reach lengths of 22 feet and weigh up to 5,000 pounds. The Great White has massive teeth, which are positioned in rows. When the Great White attacks, it bites its prey and shakes its head back and forth. The serrated teeth act as a saw and literally tear the victim apart. Actually the Great White Shark often swallows many of its own teeth in an attack. Great Whites employ several hunting skills depending on the prey. Most of the time, the shark will remain still underwater before attacking its prey from underneath. In the case of hunting some kinds of seals, the impact of the shark is so powerful that it knocks both the shark and the seal clear out of the water. With larger prey such as elephant seals, the shark will simply take a huge bite out of it and wait for it to bleed to death. When hunting dolphins, the shark will attack from above, to avoid detection from the dolphin's echolocation. Interestingly, a Great White Shark has never been observed giving birth. However, pregnant females have been caught. The Great White Shark is known to be ovoviviparous. Females give birth to eight or nine pups that are already about five feet in length upon birth, which is different from other egg-laying animals. Despite the fear of Great White Sharks, at least in part generated by Steven Spielberg's 1975 movie, Jaws, Great White Sharks do not target humans as prey. Most attacks are attributed to mistaken identity. Sharks can easily mistake humans for seals. Many human injuries caused by Great White Sharks are cases of test-biting. If a shark is unsure about a floating object, it often gives it test bite to determine what kind of object it is. While such bites do little damage to buoys  and other objects, they obviously can cause serious damage on the human body. Which category does the passage most probably belong to? A) News B) Entertainment C) Nature D) Pets
