I'm taking a test and have to guess the right answer to the question after the article. Article: It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia outweigh any financial considerations. Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects of a commercial return, and Lee's is one of them. The impact of a salary cut is probably less severe for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual opportunities. Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. "Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the... Question: What contribution can industrial scientists make when they come to teach in a university? Options: A: Increase its graduates' competitiveness in the job market. B: Develop its students' potential in research. C: Help it to obtain financial support from industry. D: Gear its research towards practical applications.

I'm taking a test and have to guess the right answer to the question after the article. Article: Eleanor Roosevelt was born in New York City on October 11, 1884. When her mother died in 1892, the children went to live with Grandmother Hall; her father died only two years later. Attending a good school in England gave her, at 15, her first chance to develop self-confidence among other girls. In her circle of friends was a distant cousin, handsome young Franklin Delano Roosevelt. They became engaged in 1903 and were married in 1905. Within 11 years Eleanor bore six children; one son died early. In Albany, where Franklin served in the state Senate from 1910 to 1913, Eleanor started her long career as political helpmate. When he was stricken with polio in 1921, she took care of him devotedly. From his successful campaign for governor in 1928 to the day of his death, she dedicated her life to his purposes. When Mrs. Roosevelt came to the White House, she understood social conditions well and she transformed the role of First Lady accordingly. She broke the tradition to hold conferences, and expressed her opinions. This made her a target for political enemies but her sincerity of purpose made her personally popular to many. As she had written: "...if truth and loyalty are stamped upon her face, all will be attracted to her..." After the President Roosevelt's death in 1945, she returned to a cottage at his Hyde Park estate; she told reporters, "The story is over." Within a year, however, she began her service as American spokeswoman in the United Nations. She continued a positive career until her strength began to wane in 1962. She died in New York City that November, and was buried at Hyde Park beside her husband. Question: Some people hated Eleanor probably because _ . Options: A: she didn't follow the traditions B: she always had better opinions C: she held too many meetings D: she became the First Lady

I'm taking a test and have to guess the right answer to the question after the article. Article: Boys and girls,as we all know,most people,especially young people ,tend to care about their hair much because hair plays a very important role in our appearance.But can you imagine what other uses hair has?Do you have any idea that human hair may become a new solar energy soutce?Before we begin with the new content of our Physics ,let me tell you a new invention first. It's reported that a Nepali teenager has designed a $32 solar panel using human hair. Milan Karki,who is 18 years old and lives in a village in rural Nepal,used human hair to replace silicon ,which is a common but expensive componet of solar panels. By using hair as a replacement,Karki says that solar panels can be produced for around $32,a price that could be halved if they were mass-produced. The solar panel works,because melanin ,which gives hair its colour,is light sensitive and can act as an elecrtical conductor.Kaiki was inspired to think of the idea by a Stephen Hawking book ,which explained how to create elecrtic energy from hair. The device that Karki has invented is capable of producing 9V or 18V of energy--plenty to charge a mobile phone. "Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months;whereas a pack of batteries would cost50p and lasts few nights,"according to The Daily Mail. The solar panel is claimed to be easy to service as the hair is easy to replace. Karki has now seng out several devices to other disrticts near his home for tetimg .He said,"First I wanted to provide elecricity for my home,then my village .Now I am thinking for the whole worle." So next time when you have a haircut,do remember to keep your hair cut down to use for energy.Perhaps you can also provide elecrticity for your home,even your village using your own hair. Question: What's the advantage of using hair as a new solar energy source? Options: A: It is a common but expensive component of solar panels. B: It can create electric energy. C: It can produce energy plenty to charge a mobile phone. D: It is cheap and easy to replace.
