Read the following article and select the best answer. Article: It's hard to avoid looking like a fool on April Fool's Day. On April 1 each year, people play tricks on each other. These tricks are usually silly rather than mean. Classmates sometimes tie each other's shoelaces to their chairs.Teachers might hand out an impossibly difficult surprise test that scares students before they realize it's only a joke. Newspapers announce fake contests (such as "Win an elephant!") and report on fake stories (like "UFO" lands in New York City). Forget gifts, songs and special foods--those are for the other holidays of the year. On April Fool's Day, the only tradition is to laugh (and maybe to cause a little bit of trouble). One April Fool's Day, when I was in high school, a group of students in my class played a very clever and funny trick on the teachers. They bought some chickens and set them free in our school cafeteria. The chickens ran all round the school, in and out of classrooms and under our feet. Feathers were flying everywhere. Teachers began running after the chickens, trying to catch them. Finally, they caught four of them. But the chickens were wearing numbered tags around their necks, and the teachers discovered that they had only caught chickens No.1, 2, 3, and 5.Where was chicken No.4? The teachers looked and looked. They couldn't find another chicken. After a few hours, they realized that the students had played another joke on them: There were only four chickens in the first place! They've been tricked by the numbers on the chickens. It's been a long time since I was in high school, but that April Fool's Day remains one of my favorite memories from those years. Question: How many jokes did the students play on teachers? - One. - Two. - Three. - Four.
Two.

Read the following article and select the best answer. Article: Five teens from Sarasota, Florida, are making music from garbage. The Garbage-Men band's instruments are made from recycled objects. The guitars are boxes. A horn is made from pipes. The keyboard is formed from old bottles. The band started about two years ago. Jack Berry decided to make a playable, homemade guitar. After some trial-and-error, he ended up building it from a cereal box, a yardstick and toothpicks. After Jack showed his creation to his friend Ollie Gray, Ollie had the idea to form a band using other homemade instruments as a way to promote recycling. "We want to show people there is more to recycling than throwing things away in the bin ," Jack, 16, said, "You can actually reuse materials." Ollie, 15, plays drums made from trash cans. Evan Tucker, 15 (bass guitar); Harrison Paparatto, 15 (horns and violin); and Austin Siegel, 15, (keyboard), round out the band. The Garbage-Men plays at local events around Sarasota, including festivals, farmer's markets and community fundraisers. Typically, the teens will set up on the street and perform popular songs from the 1960s, including classic Beatles tunes and people's favorite "Wipe Out," by The Surfaris. In between sets, they talk about recycling the offer tips for how to help the environment. while they perform, Jack's little brother Trent, 11, gives out flyers about recycling and helps sell the band's CD and other merchandise. The band donates the money from sales to charity. They have raised more than $2,500 for Heifer International. The organization gives farm animals, seeds and agricultural training to people in poor countries to help end poverty and hunger. The band--all tenth graders--tries to play a gig for America's Got Talent. The teens hope to eventually take their show on the road by touring in other states. "Music is a really good way to get a good message across to people because it's really accessible," Jack says. Their instruments may be garbage, but their message isn't. Question: Who first had the idea to organize the Garbage-Men band? - Jack Berry - Ollie Gray - Evan Tucker - Harrison Paparatto
(Answer)
Ollie Gray

Ques: Read the following article and select the best answer. Article: The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures from the earth. This idea may sound like something from a science fiction , but it is actually being taken seriously by many researchers. This suggests the future for the "red planet" will be the main topic for discussion at an international conference hosted by NASA this week. Leading researchers as well as science fiction writers will attend the event. Turning Mars into a little earth has long been a topic in science fiction," said Dr Michael Meyer, NASA's senior scientist for astrobiology ."Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars." Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal. But many experts are shocked by the idea. "We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet," said Paul Murdin from the Institute of Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident .They will find Martian life forms. Europe and America's robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet. Question: The passage is about _ . - Mars supporting life - finding water in the Mars - a plan turning Mars into a little earth - the necessity of changing Mars
Ans: a plan turning Mars into a little earth

Ques: Read the following article and select the best answer. Article: Not drying your hands thoroughly after washing them could increase the spread of bacteria, and rubbing your hands while using a traditional hand dryer could be a contributing factor, according to new research. The research looked at different methods of hand drying, and their effects on transfer of bacteria from the hands to other surfaces. The different methods included paper towels, traditional hand dryer, and a new model of hand dryer, which rapidly blows water from the hands. Our bodies naturally have bacteria all over them. However, bacteria from other sources, such as raw meat, can also survive on hands. They can be easily transferred to other surfaces, increasing the risk of cross-contamination . When the hands are washed, the number of the bacteria on the surface of the skin decreases, but they are not necessarily _ . If the hands are still damp then these bacteria are more readily transferred to other surfaces. The researchers quantified the effects of hand drying by measuring the number of bacteria on the hands before and after different drying methods. Volunteers were asked to wash their hands and palce them onto contact plates, which were then incubated to measure bacteria growth. The volunteers were then asked to dry their hands using either hand towels or one of the two hand dryers, with or without rubbing their hands together, and levels of bacteria were re-measured. The researchers found that rubbing the hands together while using traditional hand dryers could cancel out the reduction in bacteria numbers following hand washing. When hands are rubbed together during drying, bacteria that live within the skin can be brought to the surface and transferred to other surfaces, along with surface bacteria that were not removed by hand washing. A resaecher says, "Good hand hygiene should include drying your hands thoroughly and not just washing . The best method of drying your hands id using paper towels or using a hand dryer which doesn't require you to rub your hands together." Question: The research maily tells us _ . - why washing our hands is important - what pose we should hold when washing our hands - it's important to dry our hands properly after washing - how to stop the transfer of bacteria when washing our hands
Ans:
it's important to dry our hands properly after washing
