Read the following article and answer the question. Article: A 13-year-old American has made a cheap machine that can help blind people read. The blind can read by using _ - a system of small bumps that the blind touch to read the letters. The machine that makes these small bumps usually costs at least $2,000. It is called Braille writer. The American schoolboy, Shubham Banerjee, made a new Braille writer from a Lego tool that lets people create robots. Banerjee has called his new machine the Braigo - a combination of the words Braille and Lego. It costs just $ 350. It works by changing electronic text into Braille and then printing it using a computer or mobile machine. Banerjee designed his Braigo last year for a school science exhibition. Since then, he has caught the interest of Silicon Valley in the USA. The big technology company Intel spent money on Banerjee's machine last November, but they did not say how much money they put in. Banerjee also got $35, 000 from his father to help him start the project. His father works as a computer engineer at Intel. He spoke about why he gave so much money to his son, saying:"We as parents started to be interested more, thinking that he's on to something and this invention has to continue." Banerjee told the AP News: "My dream would probably be having most of the blind people...using my Braigo." Question: Banerjee's parents wanted him to continue to _ . Answer:
****
A: work on his invention

Problem:OPTIONS:
- In space our eyes are very wet.
- Tears will float around if they are big enough in space.
- People know everything about living in zero gravity.
- Gravity makes people's tears move upwards in space.

Read the following article and answer the question. Article: SPACE is a lonely place. Hundreds of thousands of kilometers from home, astronauts have a hard life. It stands to reason that, once in a while, they need to have a good cry. But this is a lot harder than it sounds. We still know very little about space, and about living in zero gravity. In fact, we are discovering new things every time astronauts take to the skies (and beyond). As The Atlantic reported in January, crying is not all that simple in space. This is because when a person normally cries, gravity makes their tears move downwards. But in a spacecraft, this is not the case. Here, there is no gravity, which is why we so often see pictures of astronauts floating around. This means that, strangely, when you cry your tears have nowhere to go. As a result, they just stick to your eyes. In May 2011, astronaut Andrew Feustel experienced this. "Tears," as he said, "don't fall off your eye... they just kind of stay there. " This can be quite painful. In space, your eyes get very dry, and the added moisture is irritating . Sometimes, things get even weirder . The astronaut Ron Parise told The Atlantic that when tears get big enough, they "break free of the eye and float around". No one can be quite sure why we cry. Why should water in our eyes have anything to do with feeling sad? If you stop to think about it, crying is a very strange thing indeed. And now, thanks to the wonders of space, it just got even stranger. Question: What can we learn from the passage? Answer:
****
A: Tears will float around if they are big enough in space.

Read the following article and answer the question. Article: You may have known several kinds of police --- traffic police, fire police and street police. But have you ever heard of energy-saving policeman? A group of 22 energy-saving policemen went to work last week in Beijing. They go around the city to see the use of energy in hotels, office buildings, shopping centers and other public places. One of their aims is to make sure that these places have set their air conditioning no cooler than 26degC. They also set up a special phone line so that people can tell them which buildings fail to follow the rule. "If everyone sets their air conditioning at 26degC, Beijing will save 400 million kilowatthour of electricity in one summer. That's one-third of all the usages of the city in the season," said a TV advertisement. Other Chinese cities, like Wuhan in Hubei Province and Yangzhou in Jiansu Province, are going to follow Beijing's steps in setting up a similar police team. As one of the fastest developing countries, China is using a lot of energy. This has a great effect on the country's environment and limited energy. From 1986 to 2005, the country experienced 20 warm winters continuously . Numbers show that Chinese cities have to spend billions of yuan solving environmental problems every year. At the beginning of this month, China made its first action plan to fight pollution. It aims to reduce energy usage by 20% and increase renewable energy up to 10% from 7% by 2010. To introduce the public to a green life, last week Beijing held a show on energy-saving technology and productions. Environment-friendly machines, such as a vending machine that helps collect used bottles, have attracted lots of attention. "We want to tell people that there are certain ways to protect the environment. Each of us can find effective ways to do it on our daily lives," said Liu Qianguang, an environmental engineer in Beijing. Question: In the year 2010 China's energy usages is going to be cut by _ . Answer:
****
A:
20%.
