Read the article and select the best 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. Question: Why is there the need to take care when you are doing the experiment? 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.

Q: Read the article and select the best answer. Article: An Apple employee is in trouble after the prototype of its top-secret iPhone5 was left in a bar. The as yet unreleased prototype was supposedly "misplaced" at Cava22 in San Francisco. Apple's security team was called in after reports that it had been sold over the internet for PS120. However, technology website Cnet.co.uk reports that the San Francisco Police Department said Apple had not reported the item as lost. Cava22 owner Jose Valle has said that neither the SFPD nor Apple have contacted him, although he does remember getting calls about a lost iPhone last month. It follows a very similar incident in April 2010 when a then-unreleased iPhone4 was left in a beer garden of a German bar in California by an Apple engineer. The lost iPhone4 was also sold over the internet to the technology blog, which paid PS3,000. The incident led to Apple strengthening its already stiff security, for it seems difficult to believe that a virtually identical incident would happen for the second time in two years. Question: What can we infer from the text? Options: A: The iPhone5 prototype was left in the bar on purpose. B: The owner of Cava22 got the iPhone5 prototype. C: The SFPD contacted the bar owner for the incident. D: The Apple officials felt quite angry about the incident.

Read the article and select the best answer. Article: Counterfeit ( ) medicines are a widespread problem in developing countries. Like other counterfeits, they look like real products. But counterfeit drugs may contain too little or none of the active ingredients of the real thing. People do not get the medicine they need. And in some cases counterfeits cause death. Twenty children in Bangladesh died last year after being given acetaminophen . The medications contained ingredients that looked, smelled and tasted like the real thing. The medicine was produced by a local drug company that used a dangerous substitute to save money. The problem of counterfeit medicines is especially serious in Africa, Asia and Latin America. The W.H.O. estimates that up to thirty percent of medicines on sale in many of those countries are counterfeit. The problem is less widespread among industrialized countries. The W.H.O. says counterfeits make up less than one percent of the illegal drug market in countries like the United States, Canada, Japan, and New Zealand. But the agency also says as much as fifty percent of the medicine sold on the Internet is counterfeit. Much is being done to fight counterfeit drugs. Several companies are developing ways to make counterfeits easier to identify. And there are existing methods, like a machine that can quickly identify chemicals in pills to confirm if the pills are real. Other ideas include things like special tracking codes for drug packages. People could send a text message with the code and get a message back, which proves that what they bought is listed in a database. Some drug makers and other companies put three-dimensional images called holograms on their products as a security device. Question: Which of the following country may have serious problems of counterfeit medicines? Options: A: Canada. B: Japan. C: New Zealand. D: India.
