- Li Jing is a student from China Youth University for Electronic Sciences.

Q: Read the following article and answer the question. Article: With limited pocket money in hand,many Chinese college students are increasingly opting to live life "low cost".One way to save money is teambuying.Online teambuying offers huge discounts and becomes popular on campus. Li Jing,a student at China Youth University for Political Sciences,for example,says she often buys movie tickets on teambuying websites.But while they offer a good opportunity to save money,Li said she would "think twice before buying them from online stores".Because many of them are "a bit chaotic  ",and have fake goods mixed among them.Then why don't the students just earn more pocket money by taking up parttime jobs?Guo Na,a teacher at the Communication University of China,said most college students were unlikely to choose workstudy programs to earn pocket money because of their intensive study schedules. A kind of card called "VELO" has become another ideal choice for many money savers.It provides allround discounts while dining out or shopping in general.Cao Zuyang,a student at the University of Electronic Science and Technology of China,often searches for sales online and buys things together with friends to cut down on costs.Cao once wanted to buy an electromagnetic oven  ,which was on sale at a shopping website.He then asked five dormitory roommates to pitch in for the oven.Each student only paid 25 yuan. Most students find it difficult to deal with the expense of accommodation while traveling.So they choose to travel to cities where they have friends and live in their dorms.For instance,Ge Rui,a student at the Hebei University of Technology,has been to many cities where he has friends."Friends can act as free guides,offer me free accommodation,give me valuable tour information,and broaden my mind at the same time," he said.He also had friends from other cities coming over and living with him when they visited his city. Question: Which of the following statements is TRUE? Answer:
Answer: You should think twice before buying something from online stores.


Problem:OPTIONS:

Read the following article and answer the question. Article: People who drink moderately  , exercise, quit smoking and eat five servings of fruit and vegetables each day live on average 14 years longer than people who adopt none of these behaviors, researchers said on Tuesday.   Much evidence has shown these things contribute to healthier and longer lives, but the new study  actually quantified   their combined effect, the British team said.   "These results may provide further support for the idea that even small differences in lifestyle may make a big difference to health in the population," the researchers wrote in the journal PLoS Medicine. Between 1993 and 1997 the researchers questioned 20,000 healthy British men and women about their lifestyles. They also tested every participant's blood to measure vitamin C intake, which shows how much fruit and vegetables people ate. Then they assigned the participants aged 45-79 a score of between 0 and 4, giving one point for each of the healthy behaviours.   After allowing for age and other factors that could affect the possibility of dying, the researchers determined people with a score of 0 were four times as likely to have died. Also a person with a health score of 0 had the same risk of dying as someone with a health score of 4 who was 14 years older.   The lifestyle change with the biggest benefit was giving up smoking, which led to an 80 percent improvement in health, followed by eating fruits and vegetables. Moderate drinking and keeping active brought the same benefits.   With this information, public-health officials should now be better encouraging behavior changes likely to improve the health of middle-aged and older people. Question: Which of the following statements is TRUE about the new study? Answer:
****
A: It made it possible to measure the benefits brought by lifestyle changes.


Read the following article and answer the question. Article: Our youngest child eagerly entered kindergarten, while our oldest child excitedly went to college--and I felt left behind. After being very happy as a stay-at-home mother of six children, I suddenly felt stuck on a dead-end road and lacked direction. An inner anxiety troubled me that life was passing by. The road, requiring expensive education, appeared too long and difficult. Thanks to supportive friends and family, I eventually discovered the road sign pointing to the ideal program at an excellent college, which offered a lot of student grants . Driving to my first class, I, aged 40, was eager and nervous. School required sacrifices : weekends for class, sleep for study, and life's luxuries  for tuition fees. But the rewards greatly outweighed the cost. The narrow and rocky road developed perseverance   and patience, while the smooth and open road built low confidence. Along the way, I met fellow travelers of all ages and interests: a 50-year-old woman who learned photography at the community college; a successful 62-year-old businessman who worked toward a nursing degree to serve in developing countries; an 80-year-old woman who enthusiastically started classes to learn how to surf the Internet, so she could keep up with the world. Twelve years after starting the journey as a non-traditional student, I graduated with a doctoral degree in literature. My children have been especially proud, calling me Dr. Mom. When you hear the small, still voice asking you to do something more or different, remember you can trust your heart. Question: How did the author feel after her youngest child entered kindergarten? Answer:
OPTIONS:
- She felt proud of her children.
- She felt eager to go back to work.
- She felt both very anxious and helpless.
- She felt worried about her children's growth.
She felt both very anxious and helpless.


input: OPTIONS:
- to focus on the differences between the two
- to lay emphasis on the similarities between the two
- to simplify the concept of the human genome
- to give an exact description of the human genome Now, answer this question: Read the following article and answer the question. Article: Imagine that the genome   is a book.The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels.There are one billion words in the book, as long as 800 Bibles; if I read the genome out to you at the rate of one word per second for eight hours a day, it would take me centuries; if I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube.This is a huge volume, a book of great length, but it all fits inside an extremely small cell nuclear  that fits easily upon the head of a pin. The idea of the genome as a book is not, strictly speaking, even a metaphor.It is true to a great extent.A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of signs into a large dictionary of meanings through the order of their groupings.So is a genome.The only difference is that all English books read from left to right, while some parts of the genome read from left to right while some from right to left, but never both at the same time. While English books are written in words of different lengthens using twenty-six letters, genomes are written entirely in words of three-letter length, using only four letters, and instead of being written on flat pages, they are written on long chains of DNA molecules  . The genome is a very clever book, because in the right condition it can both photocopy itself and read itself. Question: The real purpose of the author's comparison of the genome to a book is   _  . Answer:
A:
output:

assistant: to simplify the concept of the human genome
