[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: We usually believe what our brain tells us, but there are some amazing facts which show that the brain tricks us. As a result, we think we can see something that is not actually there or we ignore things that actually are there. Scientists Daniel Simons and Christopher Chabris have researched this phenomenon , which they call "change blindness". Their experiments show how we sometimes just do not see what is in front of our eyes because _ . Here is one of their most famous experiments. In this experiment, the participants were shown a video of two groups of people (one group in white T-shirts and one group in black T-shirts) who passed basketballs around in a hallway. Each group had three members. Simons and Chabris asked the participants to count how many times the white team passed the ball. While the two teams were passing their balls around, a person dressed up as a big bear walked through the group and stopped to look at the camera. Simons and Chabris found that about half of the research participants did not notice the big bear. Options: A Less than 25%. B About 50%. C About 75%. D Almost 100%. Answer: B About 50%. Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Last week,Chicago became the first city in the US to join the "Lights Out Plan".People turned off the lights in the city's tallest buildings,so that thousands of birds could get to their winter homes.Every year in autumn,some birds fly over Chicago on their way to the south,and come back the next spring. Lights mean danger to birds.Birds find their way by looking at the stars in the sky.Lights in tall buildings are so bright that birds may mistake them as stars.This means they can not find the right way to go home. This month,about 300 types of birds are flying over Chicago to go back to the south to live through the cold winter.Birds fly to warmer places for a few reasons.Many birds cannot live in the cold,so they fly to warmer places.But there are other reasons,too.Birds need to look for food in the south.Another reason is that they want to have baby birds.Many birds like to have their baby birds in the same "house" they lived in last year,so they fly back there. There are about 9,000 kinds of birds in the world,and about 600 kinds of birds _ .Some birds can fly a very long way.Sometimes they fly to other countries.We have fewer birds today because there are fewer places for birds. Options: A lots of birds are often ill B people kill lots of birds C there are fewer places for birds D other animals eat them Answer: C there are fewer places for birds Question:

[A]: Today we have fewer birds because _ .

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: "Would you tell me which way I should go from here?" asked Alice. "That depends a good deal on where you want to get," said the Cat. "I really don't care where" replied Alice. "Then it doesn't much matter which way you go," said the Cat. --- from " Alice in Wonderland " My name is David. And I have a brother called Mike. One day, my brother called me and asked me for some advice. He was trying to decide between two job offers: Job 1 - The first job was your typical 40 hour a week "office" job. Job 2 - The second job was more of a career in the insurance industry , where he would start at the bottom, and after many years and many long hours eventually rise to the top (if he was good). The second job did not pay as well as the first job (at the beginning), but the pay-off of the second job (in the future) was much greater than the first job. So which job should my brother take? Well the answer is...it depends. Just like the Cat was trying to tell Alice, which road you take depends a great deal on where you want to end up. Begin with the End in Mind I asked my brother what was his life's purpose. He said his purpose was to "teach," but he wanted to make a lot of money first. I told my brother to forget about the money, and I advised him to focus on his purpose. I then asked him which job best supported his end result of "teaching." He said the first job best supported his goal because he would only have to work 40 hours a week, which would give him spare time to teach. He continued on to say, "but if I take job number two, I can work hard and make more money, then I can retire early and "teach" later in life." I again advised him to "focus" on his purpose, not money. Things don't end wrong, they begin wrong! You Can't Ride Two Horses Well It would be very difficult to have a successful teaching career while you're working 70-80 hours a week in the insurance business; no one can ride two horses well. As they say, you can do anything, but not everything. I advised him to get started today by choosing the job that... Options: A you'd better have two horses B you can only ride one horse well C you can do everything well. D you can't do two things well at the same time Answer: D you can't do two things well at the same time Question:

[A]: You Can't Ride Two Horses Well means _ .

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Is your TV connected to the Internet? What about your chair or your fridge? It is possible that they are not. But in the future, most things in your home may be connected, as the so-called "Internet of things" is developing. The Internet of things may be coming sooner than you think. It is reported that during his speech earlier this year, Samsung CEO BK Yoon spent a lot of time talking about the Internet of things. He said that five years from now,every Samsung product will be part of the Internet of things, whether it's a washing machine or a vacuum cleaner . So, how do household objects that are part of Internet of things work? Well, think of a usual chair. When connected to the Internet, the chair warms up when it knows that the user has just walked into the room and is feeling cold. An Internet-connected camera, like a smart-home camera, could help people feel safer in their homes. It can recognize people's faces, and even can see when someone passes by in the dark. Then it can send you a message on your smartphone to let you know who's there. If the person is someone you don't know, it can tell you that, too. But according to MIT Technology Review, whether companies are connecting dog food bowls or security systems to the Internet, there may be problems. For example,many early connected-home devices don't have much built-in security, which means they could be hacked ,In addition, it could be difficult to get these devices to work together because they are made by different companies. To fight this, many companies have joined the Open Interconnect Consortium, which had 45 members by late 2014. So, picture this: you walk in through the front door of your home. The temperature changes to make you feel comfortable after a long day at school. Your favorite music starts playing for you. Do you think that this would be a good thing? It may happen sooner than you think. Options: A Companies which produce connected-home devices haven't joined together. B Connected-home devices may not work together and can easily get hacked. C Companies have difficulty connecting security system to the Internet.' D These new devices are produced by different companies. Answer: B Connected-home devices may not work together and can easily get hacked. Question:
