[Q]: Article: Thousands of taxi drivers in Shenyang, Liaoning province, reportedly blocked streets with their vehicles on Sunday in protest against unlicensed vehicles using taxi-hiring apps and apps-based car rental companies providing passenger services, including high-end cars. Although the drivers also complained about the withdrawal of the fuel subsidy by the government, their main complaint was the loss of business because of the rising number of Internet-based car services companies. On Wednesday, news reports came that Beijing transport authorities will take measures to stop the illegal "taxi business" of private cars through the newly rising Internet apps, following the footsteps of Shenyang and Nanjing.[:Z#xx#k.Com] It is not yet clear how the Shenyang city government will handle the issue and whether it will declare the services offered by market leaders such as Didi Dache, a taxi-hiring app provider backed by Tencent Holdings, and Kuaidi Dache illegal. But Shanghai transport regulators have set a rule, by banning Didi Zhuanche, or car services offered by Didi Dache in December. Such regulations will cause a setback to the car-hiring companies and investors that are waiting to cash in on the potentially booming business. Just last month, Didi Dache got $700 million in funding from global investors, including Singapore state investment company Temasek Holdings, Russian investment company DST Global and Tencent. Besides, the market is uncertain that Kuaidi Dache is about to finalize its latest round of funding after getting $800 million from global investors. Regulatory uncertainties, however, could cast a shadow on the future of the Internet-based car-hiring services, which have become popular in most of China's big cities. To be fair, these companies' business model is anything but bad. For example, Didi Zhuanche works side by side with established car rental companies to provide high-end car service mainly for businesspeople through the Internet and mobile phone apps. Every link in this business model chain has legal companies and services. Hence, it is hard to define it as illegal and ban it.
Question: Why did taxi drivers in Shenyang block the streets with their vehicles?
Options: (A) Because they wanted the government to increase their driving allowances. (B) Because they wanted to be educated how to use the taxi-hiring apps. (C) Because they wanted to make their main complaints known to the government. (D) Because they wanted to call on passengers not to hire the private cars.
[A]: C

[Q]: Article: We often don' t give importance to minor things thinking they won' t matter. But at times, some things look very minor but their result can be really powerful. Here are some of the efforts which can change the relationship between parents and children. Pat your child when he loses:May it be failure in the class, or on the field, speak words of encouragement to your child. The trust and confidence in your relationship will go to another level. After all, words of encouragement during failure are more valuable than words of praise after success. Give him importance, like a member of the family:Hang his painting in your room or in the office, take his opinion when you are buying furniture for the house. Your child will believe in himself and be a winner throughout. Share your own experience when your child makes a mistake:When you see your child lying or stealing, share with him the mistakes you made in your life. He' 11 know it is all right to make mistakes and that he can share with you anything. Appreciate at least one quality in your child every day:Each day look at what qualities your child possesses and appreciate him, maybe for his caring attitude, his dance skills or his observation power. Tell him how proud you are of him because of those qualities. Become his age before bedtime:Jump on the bed, have pillow fights, act silly, dance--become a child with your child for sometime. You' 11 forget all your day's stress. Try these minor things; you' 11 see the love deepen and the relationship blossom.

[Q]: Article: The US space agency NASA is looking for people to go to Mars, and stay there. This attractive career is for people who want a huge change of scenery and planet. The project is called the Hundred Years Starship, which aims to colonize other lands such as the red planet Mars. Settlers would travel to the red planet and live there forever. NASA says it would be too expensive to bring humans back to Earth. The space agency can afford, however, to send supplies to the astronaut pioneers from Earth. Astronauts would be landed on the planet's surface and would never be able to return home due to the cost. NASA has started the project with $1.6 million, and hopes to attract investment from space-living billionaires. Google co-founder Larry Page told NASA he would be interested if the cost of a one-way ticket can go down from $10 billion to $2 billion. The journey to Mars could take 4 months. Setting on the red planet would be extremely dangerous, especially given the freezing temperatures there. The thin atmosphere would be another problem as it is mostly carbon dioxide, so oxygen supplies are a must. A director in NASA said that he believed the trip might start with visiting Mars's moons first. He claimed that humans could be on Mars's moons by 2030. Many scientists think colonizing space is absolutely necessary. Steven Hawking believes we must move to other planets to survive as a species. He said: "Once we spread out into space and establish independent colonies, our future should be safe." Scientists Dirk' Schulze-Makuch and Paul Davies also call it a "desirable goal", though there surely are huge risks to explore new lands.
Question: Which of the following is TRUE about the Hundred Years Starship?
Options: (A) It has cost NASA around $10 billion. (B) It is expected to be conducted on Mars in 2030. (C) It aims to explore new lands in the universe. (D) It is a project first raise by Steven Hawking.
