Read the following article and select the best answer. Article: More than four decades ago British scientist Robert Edwards first witnessed the miracle of human life growing inside a test tube at his Cambridge lab. Since that ground-breaking moment, more than four million babies have been born through IVF and in 2010 his great contribution to science was finally recognized as he was awarded the Nobel Prize for medicine. The prize for Dr Edwards, who was given a Daily Mirror Pride of Britain Award in 2008, includes a PS900,000 cheque. The Nobel Assembly described IVF as a "milestone in modern medicine". With the help of fellow scientist Patrick Steptoe, the Manchester-born physiologist developed IVF -- leading to the birth of the world's first test tube baby. Dr Steptoe died 10 years later but their work has transformed fertility treatment and given hope to millions of couples. It was a scientific breakthrough that transformed the lives of millions of couples. They said: "His achievements have made it possible to treat infertility, a disease which makes human unable to have a baby. This condition has been afflicting a large percentage of mankind including more than 10% of all couples worldwide." Louise Brown, the world's first test tube baby, made international headlines when she was born in Oldham, Gtr Manchester, in 1978 to parents Lesley and John who had been fruitlessly trying for a baby since 1969. Ivf-in-vitro fertilisation is the process whereby egg cells are fertilised outside the body before being implanted in the womb. After a cycle of IVF, the probability of a couple with infertility problems having a baby is one in five -- the same as healthy couples who conceive naturally. Professor Edwards, who has five daughters and 11 grandchildren, began his research at Cambridge University in 1963, after receiving his PhD in 1955.He once said: "The most important thing in life is having a child. Nothing is more special than a child." With the help of fellow scientist Patrick Steptoe, Prof. Edwards founded the Bourn Hall clinic in Cambridge shire, which now treats more...

Article: From New Delhi to Beijing,commuters spend a lot of time stuck in traffic.In the United States,Los Angeles(L.A.)and San Francisco tie for second place for having the worst traffic problems.Washington,D.C.is in first place with the worst traffic,according to the Texas A&M Transportation Institute. In L.A..drivers spend sixty-one hours every year stuck in traffic.These drivers know all too well how bad the traffic can be.Professor Cyrus Shahabi also knows about traffic jams.He said,"It's a prison of cars.There are too many cars,you can't move around a lot.I live more than 65 kilometers from my office at the University of Southern California.in L.A..I'm always late even with the help of a navigation system.I thought it would be appropriate to do something to solve it." Therefore,he and PhD student Ugur Demiryurek decided to develop an app for that.The ClearPath app claims to do what other navigation systems cannot.Professor Shahabi says his program uses historical data to predict traffic conditions even before the driver leaves the house. ClearPath uses two and a half years worth of traffic data from 9,000 sensors on the roads of L.A..It also collects information on accidents. Professor Shahabi says his system does more than just respond to current traffic conditions.With ClearPath,he says,a driver can enter what time he wants to leave on a specific time and date,and ClearPath will give the fastest route.It looks at the entire road network,including surface streets as well as highways,before the driver hits the road. Ugur Demiryurek says they will launch the free ClearPath app for roads in L.A.in two months.In a year,he and Professor Shahabi hope to have ClearPath available nationwide and overseas once they can collect traffic data from other cities. "I thought always that L.A.had the worst traffic,but now I know that Shanghai,Beijing,Seoul,Tokyo,believe it or not,Singapore,Hong Kong definitely are examples that can immediately use this." Question: The ClearPath app can mainly be used to _ . - predict traffic conditions - kill the boring time - avoid the traffic accidents - collect the current news
avoid the traffic accidents

Q: Read the following article and select the best answer. Article: The Collections of Chinese Ancient Cultural Relics Abroad: Volume Victoria and Albert Museum has just been published, the fruit of ten years' efforts by Chinese experts. The book is the first of an upcoming series that centers on ancient cultural heritage collections in different museums around the world. The book details 195 out of 18,000 items now in the Victoria and Albert Museum in England. More than 1.64 million ancient Chinese artifacts have been transported out of China because of different reasons such as wars and smuggling since the mid 19th century. More than 200 museums in 47 countries hold such collections, according to a report from UNESCO. "The information we now have about these pieces is still very patchy ," said Lu Zhangshen, curator of the National Museum of China. "In order to have a clearer picture about these items, National Museum of China decided to start the Chinese Ancient Cultural Relics Abroad book project in 2005. But after we began, we found it really difficult to collect information for every piece from each museum. That's why the first volume took us ten years." "The pieces in the book include 102 porcelains , 31 bronzes , 22 lacquer , 10 enamel vessels and so on," Liu Mingqian from Victoria and Albert Museum said. According to the National Museum of China, the volume of the Japanese museum Sen-oku Hakuko Kan is coming out soon and the museum will seek more cooperation from museums worldwide to accelerate the project. Question: Which of the following best describes Lu Zhangshen's attitudes towards the Chinese Ancient Cultural Relics Abroad book project? - worthwhile but expensive - reasonable but worthless - meaningless but hard - meaningful but difficult
A: meaningful but difficult

Read the following article and select the best answer. Article: Fire fighting is a serous matter, knowing what to do during a fire can save people's lives. It is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency exits, but not elevators. From the lower floors of building, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury. The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about twice the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building. Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked into the room. On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury. Bushes and trees can help you to have a soft landing. Question: The writer suggests that _ - breathing in smoke might be harmful - smoke will enter the room through an open window - fresh air can't reach the second floor window - to keep you head low will help you to escape a fire
(A).
smoke will enter the room through an open window
