Read the following article and select the best answer. Article: Mr. Sankaram, a physics teacher, was known for his antics in his classroom to make the dull lessons in physics lively and interesting. Mixing different chemical drugs in the lab to become new substances in chemistry makes students excited. While studying botany or zoology, students can visit a garden or zoo. But physics limits students to listening to the boring lectures which are hard to understand. For example, why an apple dropping from a tree travels downwards but not upwards. But Mr. Sankaram's classroom antics to cause students to listen to topics such as how sound travels in air or why light travels faster than sound made him stand out from the rest of the teachers. At that time, most students in our school attended the college to please their parents, and some parents were proud of their children for simply attending a college, no-matter whether they benefited or not. They didn't study hard. But a few students were diligent and they wanted to study pre-medical courses to gain admission into the medical school. The schooling of pre-medical courses was very expensive. The college was next to the medical school. The wall separating them was about four feet high. Few tried to jump over the wall to get free pre-medical courses. Doing this was at risk of injuries and the climbing was forbidden. The college where Mr. Sankaram taught was known for unruly and naughty students. The unruly students usually sat at the back of the classroom. When a student from the back of the classroom tried to disrupt the class, Mr. Sankaram would say, "Dare you go ahead to make noise? Can you jump over the four-foot wall to get into the medical school?" The student's face went red and he became silent. In the physics class . I sat in the first row to escape from the troublemakers at the back. One day during the class. Mr. Sankaram unexpectedly asked me, "Can you jump over the four-foot wall?" I shook my head and answered, "No, sir, I couldn't jump over a one-foot wall, let alone a four-foot wall." Mr. Sankaram wasn't satisfied... Question: Mr. Sankaram's failing to get into the medical school _ . - resulted in getting his nickname "four-foot" - caused him to be forever depressed and to cry every day - made him work hard to let his students realize his dream - made him complain the life was unfair and he was not lucky
made him work hard to let his students realize his dream

Read the following article and select the best answer. Article: The rise of multinational corporations , global marketing, new communications technologies, and shrinking cultural differences have led to an unparalleled increase in global public relations or PR. Surprisingly, since modern PR was largely an American invention, America's relations is being threatened by PR efforts in other countries. Ten years ago, for example, the world's top five public relations agencies were American-owned. In 1991, only one was. The British in particular are becoming more sophisticated and creative. A recent survey found that more than half of all British companies include PR as part of their corporate planning activities, compared to about one-third of U.S. companies.It may not be long before London replaces New York as the capital of PR. Why is America lagging behind in the global PR race? Firstly, Americans as a whole tend to be fairly provincial and take more of an interest in local affairs. Knowledge of world geography, for example, has never been strong in this country. Secondly, Americans lag behind their European and Asian counterparts in knowing a second language. Less than 5 percent of Burson--Marshall's U.S.employees know two languages. Ogilvy and Mather have about the same percentage. Conversely, some European firms have half or more of their employees fluent in a second language. Finally, people involved in PR abroad tend to keep a closer eye on international affairs. In the financial PR area, for instance, most Americans read the Wall Street Journal. Overseas, their counterparts read the Journal as well as the Financial Times of London and The Economist, publications not often read in this country. Perhaps the PR industry might take a lesson from Ted Turner of CNN (Cable News Network). Turner recently announced that the word "foreign" would no longer be used on CNN news broadcasts. According to Turner, global communications have made the nations of the world so interdependent that there is no longer any such thing as foreign. Question: What is the immediate cause of the downfall of America's public relations? - The number of US public relations agencies had greatly decreased by 1991. - Other countries have increased their efforts in public relations. - On the global scale, cultural differences have significantly shrunk. - The British companies are becoming especially sophisticated and creative in public relations.
Other countries have increased their efforts in public relations.

A major football event will happen in the South American country later this month, but with teams of robots playing the game, which is known as soccer in the United States. The robot teams are guided by teams of humans from around the world. The event is known as RoboCup. Technology students at the University of Pennsylvania are trying for their fourth victory at the competition, which is held this year in the coastal city Joao Pessoa. The students have won the last three RoboCup competitions. Watching robots play football is similar to watching children play the game. The kicks are not good, there's a lot of falling down, and people are there to guide and support the team members. Jian Qiao Li is one of the leaders of the University of Pennsylvania team. He says one goal he has for the robot team is to make sure the machines can find the goal and the ball. He also wants the robots to be able to know where they are on the playing field. And he wants the team to be able to better control the walking and kicking abilities of the robots. Qin He is another leader of the robot team. She says the abilities of the robots increase every year. Ms. He says the US team is meeting its goals. The robots know the differences between the colors green and red, and they can decide where to go and where the ball is on the playing field. She says if there are three robot players on the field at the same time, they will communicate with each other to decide the different responsibilities for each robot. U. S. Team member Christopher Akatusuka hopes for another victory in Brazil. The team has won the RoboCup the past three years in the Netherlands, Mexico and Turkey. "They have every good team player right now. As long as their detection is good, I think they'll be very competitive; we just hope to compete against the real good German teams eventually, because the Germans always do very well, " says Akatsuka. Mr Akatsuka says RoboCup... Question: Akatsuka's final hope for his robot team is _ . - to invent the best software - to win the championship in Brazil - to make the best decision - to compete with humans
