Read the following article and select the best answer. Article: Few people ever took notice of Mr. Jimmy Tan whenever he entered a room. He was a shy, quiet and simple man who preferred to keep to himself in public. On the other hand, Mr. Thomas Kim, a fellow scientist, was a man everyone would notice on the streets. He wore bright outfits with huge flower prints, spoke with a booming voice, and his laughter could be heard from all corners of a room. In addition to the differences in their characters, Mr. Kim and Mr. Tan were also great _ at work in the Institute of Future Science. On Christmas Eve, everyone left work early to celebrate the special occasion, except for Mr. Tan and Mr. Kim. They were in their laboratory analyzing the results of their latest experiments. Mr. Tan realized that something special was taking place in his experiment --the bacteria he had cultured were growing extremely quickly under high pressure and at a very low temperature. After noting down the findings in his notebook, he left the room to prepare for another round of tests. Shortly after, Mr. Kim entered. "Hey Jimmy," Mr. Kim called out, "do you have an extra copy of the laboratory booking form?" There was no reply, so Mr. Kim looked through Mr. Tan's things. He soon found Mr. Tan's notebook and was horrified to see that Mr. Tan had managed to make one of the most important discoveries in modern science. He then looked into the deep-freeze cupboard where a dish containing the bacteria was kept. He put _ into his pocket and returned to his own laboratory. Mr. Tan came back an hour later to find his notebook and the dish missing. He knew that Mr. Kim had taken them and went to Mr. Kim's laboratory to find out. When he opened the door, he found Mr. Kim lying on the floor motionless. His face was pale and his skin had turned black. The deadly bacteria had been handled improperly. He shook his head and left. Question: Which of the following is true according to the passage? - Mr. Kim was afraid Mr. Tan might succeed ahead of him. - Mr. Tan's bacteria grew very fast in a warm container. - Mr. Tan worked much harder than Mr. Kim. - Mr. Kim was so tired that he fell down into sleep.
Mr. Kim was afraid Mr. Tan might succeed ahead of him.

Read the following article and select the best answer. Article: He must have been completely lost in something he was reading because I had to tap on the windshield to get his attention."Is your cab available ?"I asked when he finally looked up at me.He nodded,then said apologetically as I settled into the back seat,"I'm sorry,but I was reading a letter."He sounded as if he had a cold."I am not in a hurry,"I told him."Go ahead and finish your letter."He shook his head."I've read it several times already.I guess I almost know it by heart." "Letters from home always mean a lot" I said. "This isn't family," he replied."although it might just as well have been family.Old Ed was my oldest friend.In fact,we used to call each other 'Old Friend'--when we'd meet.I'm not much good at writing." "I don't think any of us keep up our correspondence too well,"I said."I know I don't,but I take it he's someone you've known quite a while?" "All my life.We were kids together, went to school together and all the way through high school.""There are not too many people who've had such a long friendship,"I said."Actually,"the driver went on,"I hadn't seen him more than once or twice year over the past 25 or 30 years because I moved away from the old neighborhood and you kind of lose touch even though you never forget." "You said 'was'.Does that mean---?" he nodded."A couple of weeks ago." "I'm sorry" He didn't say anything more,and we rode on in silence for a few minutes.But I realized that Old Ed was still on his mind when he spoke again,almost more to himself than to me." "I should have kept in touch with him." "Well,'' I agreed,"we should all keep in touch with old friends more than we do.But things come up and we just don't seem to find the time." When I got to my hotel room I didn't unpack right away.First I had to write a letter --and mail it. Question: Why did the driver said sorry when the writer settled into the back seat? Because - he didn't want to take the passenger - he didn't notice the writer - he had a cold and could not speak - he didn't feel well
(Answer)
he didn't notice the writer

Read the following article and select the best answer. Article: Finally, the long-awaited flying car is almost here. AeroMobil, a Slovakian company, plans to start selling its creation, the AeroMobil3. 0, in 2017. The company claims on its site that the vehicle "transforms in seconds from an automobile to an airplane" by using "existing infrastructure created for automobiles and planes."The vehicle is petrol-powered and has wings that fold, which allows it to be parked like a car, though it is nearly 20 feet long. The company's website features a video where the AeroMobil 3. 0 drives out of a hangar ( )and goes down a highway, sharing the road with ordinary cars until it arrives at an airstrip. The car then unfolds its wings and takes off from a stretch of grass, rather than a paved tarmac , and flies through the air like any other small airplane. AeroMobil spokesman Stefan Vadocz said his company hasn't decided on an exact price because it's not ready yet."The prototype is a work in progress," he said in an email. But he said the price would be several hundreds of thousands of euros---somewhere in between a sports car and a light sports aircraft. The vehicle seats two people---the pilot and a passenger---and its single propeller is located at the rear of the plane. The company said the car's top speed on the road is at least 99 mph and while flying it is at least 124 mph. It can fly for 435 miles before running out of fuel. It has a steel framework and carbon coating and is powered by a Rotax 912, a four-cylinder aircraft engine from BRP of Austria. Flying cars aren't exactly new. The concept has been around since long before The Jetsons popularized the idea in the 1960s. It has been a regular topic in Popular Science ever since World War I ace, Eddie Rickenbacker, wrote about it in 1924. But getting a practical, reliable flying car off the ground has been a serious challenge. Glenn Curtiss discovered this in 1918 when he developed the Curtiss Autoplane. It turned out to be more of a hopper than a flyer, so it failed to become popular with the public. Question: What is the biggest difference between the AeroMobil 3. 0 and other airplanes? - It is powered by aircraft fuel. - It can fly as fast as airplanes. - It has a propeller. - It can take off from a stretch of grass.
It can take off from a stretch of grass.
