Read the following article and select the best answer. Article: Texting walkers aren't just an annoyance to other walkers, Australian researchers armed with movie special-effects technology have determined scientifically that they're threats to themselves. Using motion-capture technology similar to that used for films, researchers concluded that texting while walking not only affects balance but also the ability to walk in straight line. "Some people like checking emails while walking to work in the morning" said the study co-author Hoorn, "but they may not know it has a serious effect on the safety of themselves". Other facts have also proved this. A tourist from Taiwan walked off a pier near Melbourne last month while checking Facebook, bringing a sudden and icy end to a penguin-watching visit. Another person who was too _ in his phone to notice dangers walked straight into the fountain in front of a shopping mall. The Australian study involved 27 volunteers, a third of whom admitted having knocked into objects while texting. They were asked to walk 8.5 meters three times--once without phones, once while reading text and once while writing text, when eight cameras recorded their actions. They found the volunteers using the phone walked slower, and, more seriously, they locked their arms and elbows in like "robots", which forced their heads to move more, throwing themselves off balance. "In a pedestrian environment, inability to maintain a straight path would be likely to increase potential for traffic accidents", said Mr. Hoorn. "The best thing to do is to step aside and stop, or keep off the phone." Authorities world-wide have taken note. Signs on Hong Kong's subway system advise passengers in three languages to keep their eyes off their phones. Police and transport authorities have highlighted the danger in Singapore, where the Straits Times newspaper recently declared cellphone-distracted road crossing as "bad habit No. 2" contributing to the rising number of road deaths. Some U.S. states, including New York and Arkansas, are considering bans on what they're calling... Question: According to the passage, people texting while walking usually _ . - do not influence other walkers - do harm to their eyes - put themselves in danger - can still walk straight
put themselves in danger

(Question)
Read the following article and select the best answer. Article: Mayor Boris Johnson Monday outlined plans to make London "the cleanest, greenest city on Earth" by the 2012 Olympics and called for commitments from other world cities at a climate change conference, leaders of the world' s 40 largest cities are meeting in Seoul this week for a summit on combating global warming -- the third to be held since 2005. "What we should do in Seoul is agree that we will stop the endless addiction of mankind to the internal combustion engine ," said Johnson. He said at a press conference the world's cities consume 75 percent of the world's energy and produce 80 percent of the emissions which cause climate change. "The problem of our planet is an urban problem," Johnson said. He said the British capital wants to use the Olympics "to drive the greening and the improvement of our city" and noted that London is committed to reduce carbon dioxide emissions by 60 percent by 2025. Johnson said the key measure was being taken to solve problems relating to housing and commercial buildings, which accounted for 70 percent of carbon dioxide emissions in London. This involved retrofitting -- installing lagging -- in large numbers of public buildings. Johnson proclaimed himself a "passionate cyclist" and said he would push ahead with cycle superhighways around London. London's air quality problem, he said, was caused by vehicle emissions from 8,300 worn and used diesel buses, which could be replaced by low-carbon vehicles. In addition, there were also 32,000 taxis running on diesel fuel, which could be replaced by electric vehicles. Johnson said there would be a few programs in the next few years to produce a "cleaner, greener" bus for the city. "The age of the diesel bus has got to be over in London." Question: If the passage was continually written, the following might be _ . - measures to end the age of the diesel bus - measures to reduce carbon dioxide emissions in London - measures to solve housing and commercial items - measures to replace the old and used vehicles
(Answer)
measures to end the age of the diesel bus

Ques: Read the following article and select the best answer. Article: We Chat, the Chinese social media smartphone app, saw an increase in user numbers of 41 per cent year on year to 500m at the end of 2014, in a sign that parent company Tencent is extending its reach for the mobile internet. Revenue grew 24 per cent to Rmb20.98billion, slightly higher than forecasts, driven mainly by online gaming revenues. It is unclear how much WeChat contributed to Tencent's revenues but the app's growth is a strong indicator of the company's long-term health as it tries to adjust its business to be more suitable for mobile devices. "We extended our leadership in games and online media, and made breakthroughs in emerging platforms such as online security . . . and mobile payments," Ma Huateng, Tencent chairman, said in a statement. WeChat is the second highest ranked app in China, behind QQ, Tencent's other chatting app, which claimed to have 815m registered monthly users at the end of 2014. However, that figure is more than the total number of internet users in China, which the government puts at 640million. Tencent has been unwilling to earn money through WeChat by flooding it with advertising, which could reduce efforts to increase the user base. But this is expected to change. Some analysts predicted that advertising would be introduced on later this year. Early attempts to test ads on the service have not always gone smoothly. After a BMW ad was introduced on some users' feeds in January, many users complained of "discrimination" by Tencent's data mining algorithm. They said it unfairly considered them as not wealthy or successful enough to view the sought-after BMW ad. Question: What is the main driving force of the Tencent's income growth? - QQ - WeChat - Online gaming - Advertisments
Ans: Online gaming

Question: Read the following article and select the best answer. Article: Mike Maietta was eating lunch when he got a text message from his mom. "Notre Dame," it said. " _ !" Mike, a senior at a Californian high school, shouted with joy. The big envelope meant that the excellent university in Indiana had offered him a place in its Class of 2013. But the $51,300 annual fee is a big trouble. So Mike and his parents are considering offers from several other colleges and are figuring out the costs of tuition, housing and holiday trips home. This year, money is the driving factor for a growing number of high school seniors, who have to decide what colleges to attend this fall. Less jobs and house prices have changed family spending. "We're excited that Mike got into eight great schools," said Mike's father, an engineer at Microsoft. "But if you consider going to school out of state, you've got to think about all of the other costs: moving, flying back and forth for the holidays. You're looking at about $3,000 a year, just for travel." As families weigh their choices, some are going back to financial aid offices hoping help packages can be increased. Rachel Brown was happy to get a thick envelope from New York University (NYU). Although she has always wanted to live in Manhattan, she is seriously considering the University of California San Diego (UCSD), because of the high cost in New York. "The tuition for NYU is twice as much as UCSD," said Rachel, 17. "My mom doesn't want me to have a big debt when I graduate, and I don't want that either. I'd have to take out a loan of $15,000. I'll check and see if there's any way that NYU can offer me any financial aid." More than 7.6 million American students have filled out the Free Application for Students Aid, 19.9 percent increase over last year. This month the Federal Department of Education urged college financial aid officers to give more help to certain families. A record 30,428 students applied for 2,300 places at Stanford, partly because the university increased financial aid for families earning below $10,000. Question: The passage mainly focuses on _ - the calculation of different costs including tuition - the extremely hard financial situation in America - the excitement of students' being able to enter ideal colleges - the financial crisis of families over college entrance
Answer:
the financial crisis of families over college entrance
