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: What does the Braigo change into Braille? Options: A: Photocopies. B: Voices. C: Electronic text. D: Computer languages.

Read the article and select the best answer. Article: London used to be "foggy" for the same reason that cities like Beijing or Chongqing are "foggy" today. The "fog" was in fact smog, a mixture of smoke and fog. In other words, it was made by air pollution. In London, some of this pollution came from factories, but much of it came from the coal that people burnt in their houses to keep warm during the winter. By the 1950s, London's smog problem had become so bad that the government decided to do something to clean the air. A new law was made and nobody could burn coal in any British city. Within a few years, the air became much cleaner. There were no more " _ ". Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago. However, this problem is more difficult for Chinese cities to solve. One reason is that more of the pollution comes from the factories, rather than from coal burnt in people's houses. If these factories were closed, this would harm the economy and lots of people would lose their jobs. Another reason is that changing from coal to cleaner fuel , like gas, is quite expensive. However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution. As a result, there are fewer "pea-soupers" in Beijing than there used to be. Question: Which sentence is NOT true? Options: A: Air pollution is serious in Beijing and Chongqing. B: Using coal is much more expensive than using gas. C: Factories made much more pollution in China. D: The reasons of air pollution in London and Beijing are different.
