Article: Considered one of Europe's two "bicycle capitals" along with Amsterdam, Copenhagen counts more bicycles than people and cycling is so popular that its numerous bike paths can become crowded. Two-wheeler traffic jams are especially regular on the main Noerrebrogade road used by around 36,000 cyclists a day. "You have to elbow your way in to go forward and some cyclists aren't always thoughtful," complains 22-year-old university student Lea Bresell. The creation of bike highways "comes right on time", says Danish Cyclist Federation Spokesman Frits Bredal. "Copenhagen's roads are overloaded with people who want to ride their bicycles in all kinds of weather," he says. "If in the 1960s Danes viewed the car as the symbol of freedom, the bicycles have supposed that role today," Bredal says. "It's a _ of transportation used by all social classes, even politicians ride bikes," he says. It is on crowded Noerrebrogade--the busiest bicycle street in Europe, according to the cyclist association--that city planners have decided to build the first of Copenhagen's environmentally friendly roads. The jammed bike paths will be widened up to four metres on either side of the road, which itself will be reserved for bikes only. The idea is to make Noerrebrogade "Europe's great cycling street", says Andreas Roehl, Copenhagen government's bicycle program manager who is also known as "Mr. Bike". But Roehl is not content with making life easier for Copenhagen's inner-city cyclists: He wants to get suburbanites out of their cars and onto two wheels as well. His goal is to hike the percentage of suburban commuters cycling to and from the city from the 37 percent it is today to 50 percent by 2015. Question: Why does Copenhagen plan to build the first bike highway? - Because bike highways are environmentally friendly. - Because it's a part of the city's development program. - Because the inner-city commuters urge that it should be built. - Because too many bicycles cause the paths to be crowded.
Because too many bicycles cause the paths to be crowded.

But rights activists say the government and private groups need to do more to help children in need. A small child protection service in Shanghai is trying to stop neglect and violence against children. Gege is seven years old. She has been homeless for almost half her life. Her mother suffers from a mental condition. They lived on the streets in Shenzhen for more than three years. A man named Xiao Xudong learned about Gege. He told her story to the local media earlier this year. Government officials heard the story and found help for Gege and her mother. The mother began to receive treatment for her mental problems. Gege was sent to a centre for children who had lost both parents. She was later re-united with her father. Her story has a happy ending. But social workers are not yet celebrating. Xiao Xudong spoke on Skype: "We have many child protection organizations, but why do we still have so many children being abused and neglected?" Recently, Chinese newspapers and magazines reported on repeated cases of child abuse in the country. The reports shocked many people and led the government to strengthen measures to protect children's rights. Xie Chang'e is a lawyer. She offers legal assistance at a child protection service called Hope Home. Ms. Xie said that China has laws to protect children's rights. But the laws are often unclear, she added, and difficult to put into effect. However, the government is starting to recognize the problems in the child welfare system. New rules state that parents or legal guardians who sexually abuse, sell, abandon or violently hurt children will lose their legal right to care for them. Ms. Xie supports the new regulations. She says they are a good way to help protect children. But she says police and other officials do not know about the regulations or do not always follow them. She also notes that the new regulations have the force of law, but they... Question: What causes the laws to protect children's rights to be ineffective? - The laws are so complicated that people don't understand them. - The laws are so general that they are hard to put into effect. - The laws are often ignored by the government. - The laws are not practical.
The laws are so general that they are hard to put into effect.

Q: Read the following article and select the best answer. Article: By 2050, half of the world's population will live in the tropics--the ly warm belt that circles the globe--according to State of the Tropics, a report released today. Rapid population growth, along with economic growth, means that the region's influence will grow in coming decades, the authors of the 500-page work predict. The project, first launched in 2011, aimed to answer one significant question: Is life in the tropics improving? To find out, the researchers analyzed environmental, social, and economic indicators collected over 6 decades. It finds that the region has made "extraordinary progress" in many areas. For example, more people have access to safe drinking water, and the number of protected areas is increasing. The tropics also have outperformed the rest of the world in economic growth over the past 30 years. However, some challenges remain. Investment in research and development, for example, has increased cautiously, but tropical nations still invest less than the rest of the world. "As a proportion of GDP the Rest of the World invests almost four times as much in research and development than the Tropics." concludes the report. The report also includes a new analysis of how climate change will affect the region. Many plant and animal species are moving poleward in an attempt to stay within their preferred environmental conditions in the tropics, the authors write. However, some organisms may not be able to keep pace with the changing conditions, they predict. As a result, they can experience population declines or go extinct. In addition, an expanded tropical zone also threatens health and safety issues, the authors warn. As regions become more suitable to insects such as mosquitoes and ticks, the spread of insect-borne diseases such as malaria, dengue, and Lyme disease could rise, causing a burden to human health and the economy. Bruna, a researcher, says he sees a lot to be concerned about in the report. "While we've made incredible advances in some areas, I think the risks for the tropics... Question: What was the original purpose of the project State of the Tropics? - To answer if life in the tropics is improving. - To do research about environment, society and economy. - To warn people of the problems in coming decades. - To help the development in the tropics.
A: To answer if life in the tropics is improving.
