Read the following article and select the best answer. Article: Federal regulators Wednesday approved a plan to create a nationwide emergency alert system using text messages delivered to cell phones. Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry's trade association, CTIA, estimates more than 48 billions text messages are sent each month. The plan comes from the Warning alert and Response Network Act, a 2006 federal law that requires improvement to the nation's emergency alter system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies. "The ability to deliver accurate and timely warning and alert alters through cell phone and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan. Participation in the alert system by carriers -- telecommunication companies -- is voluntary, but it has received solid support from the wireless industry. The program would be optional for cell phone users. They also may not be charged for receiving alerts. There would be three types of messages, according to the rules. The first would be a national alter from the president, likely involving a terrorists attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction emergencies, or so-called Amber Alerts. The service could be in place by 2010. Question: What is the purpose of the approval plan? - To warn people of emergencies via message. - To popularize the use of cell phone. - To estimate the monthly number of messages. - To promote the wireless industry.
To warn people of emergencies via message.

Read the following article and select the best answer. Article: Do you know anything about the history of weather? Don't look at the sky. Don't look for old weather reports. Looking at the tree rings is more important. Correct weather reports date back only one century, but some trees can provide an exact record of weather even further back. It is natural that a tree would grow best in a climate with plenty of sunlight and rainfall. It is also expected that little sunlight or rainfall would reduce the growth of a tree. The change from a favorable to an unfavorable climate can be found out by the reading pattern of rings in a tree trunk. To find out the weather of ten years ago, you can count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that plenty of sunny and rainy weather occurred. If the rings are close together, then the climate was bad for the tree. Studying trees is important not only for the history of weather, but also for the history of man. In an area of New Mexico you can find only sand -- no trees or people. However, many centuries ago a large population lived there. They left suddenly. Why? A scientist studied the pattern of the rings of dead trees that had grown there. He made up his mind that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move. In this example studying tree rings uncovered an exciting fact about the history of man. Question: The ancient people usually lived where there were plenty of trees mainly because _ . - trees were materials for fires and buildings - trees could supply them with fruit and food - rees could supply them with shades - trees provided an exact record of weather
trees were materials for fires and buildings

Q: Read the following article and select the best answer. Article: In James Cameron's fantasy films, such as Avatar and The Abyss, the unexplored is decorated in color and filled with alien danger. But on his dive to the deepest place on Earth, which took place on a Sunday last month, reality proved far different: white, deserted, and dull. "I felt like I literally had gone to another planet and come back," Cameron said after returning from the cold, dark place in the western Pacific Ocean, nearly 7 miles (11km) below the surface. "It was a very fantastic day." Cameron is the first person to explore the deepest valley in the ocean since two men made a 20-minute trip there in 1960. He spent about three hours gliding through the icy darkness, brightened only by lights on the one-man sub . This deepest section of the Mariana Trench is so untouched that at first it appeared dull. But there's something strangely interesting about the first pieces of video that Cameron shot -- a sense of aloneness. "It's really the sense of isolation, realizing how tiny you are down in this big, black and unexplored place," the Titanic director said. The wordless minute-long video, released by sponsor National Geographic, shows Cameron's sub gliding across what he calls "the very soft, almost gelatinous flat plain." To Cameron, the main thing was to appreciate being there. "There had to be a moment where I just stopped, and took it in, and said, ' _ What does that mean?'" Cameron told reporters during a conference call. The trip was only about half as long as planned because Cameron's battery ran low. He said he would return and film it in 3D for later viewing. "I see this as the beginning," Cameron said. "It's not a one-time deal and then moving on. This is the beginning of opening up this new frontier." Question: Which of the following statements is TRUE according to the passage? - Cameron's fantasy film, Avatar was inspired by his dive to the deepest place on Earth. - Cameron glided through the icy darkness alone by lights of the one-man sub. - Cameron didn't stay at the bottom of the ocean as planned because he was worn out. - Cameron felt bored when he went to the deepest valley in the ocean.
A: Cameron glided through the icy darkness alone by lights of the one-man sub.
