Article: Turning on the TV, a wonderful scene comes to your eyes -- a group of men, tall, strong and handsome, and women, young, beautiful and attractive, too. Together they eat in the finest restaurants, traveling everywhere around the world by luxurious planes and pleasure ships. They are models. Do you envy them? What sort of life are models leading? Is it a wonderful life for a young lady or a young man? A few models are well-known actors or actresses who can make a lot of money only by showing themselves off in commercials. But the majority of them are just curious to see what it is like. They'd like to be models just because they are attracted by what they imagine -- models earn a lot of money and lead a glorious life. This is true for those who are very successful. However, most models find it difficult to get work. Very few can earn enough to live on, and for all models their expenses are high. Their agents claim about 20% of the earnings, and no model will get very far without a clever agent. Besides, they have to buy good clothing. They also have to pay to travel to interviews and reach the places where the work is to be done. Interviews for a model job are known as cattle-markets in the modeling world, and not without a good reason. A top model can choose his or her work, demand and receive high fees and has his or her expenses paid. But for most models, the situation is quite different. And agent or employer inspects each model much as a farmer inspects cattle at a market. Intelligence, qualifications and personal characteristics count for little against good looks and tight figures. For all except the very few lucky ones, the life of a model is a continual search for work, trying to sell himself or herself in the face of fierce competition and, sometimes, not particularly moral standards on the part of some employers. Immigration officials at airport look suspiciously at a girl whose passport shows her occupation as "Model", and these are men and women of considerable experience of the world. It comes no... Question: What may be the author's attitude towards modeling? Yes or no, is the answer "Before being crazy about a model job, young people should be aware of the difficulties."?

No

Article: The largest known outbreak of the lethal Ebola virus in West Africa is prompting authorities as far away as Asia to take preventive measures, although scientists say a global spread of the disease is unlikely. At South Korea's Incheon International airport, a major hub for air travel in Asia, quarantine inspections of arriving passengers are being enhanced. Authorities say all passengers are being recorded by an infrared camera to detect fevers because Ebola is becoming a big concern. The incubation period of the Ebola virus is between two and 21 days, during which time an infected person might not show any signs of infection. In Hong Kong, the Center for Health Protection says public hospitals will begin to report and test all those who developed fever who, within the past 21 days, traveled to the three affected African countries. Singapore's health ministry is urging the public there "not to be alarmed." It has issued a statement deeming Ebola to pose "a low public health risk to Singapore," in part because "there is low travel connectivity to West Africa where the current outbreak remains limited to." Some airlines have suspended flights into the affected region. But health authorities say there is little risk of passengers contracting the virus on a flight from an infected person.Dr. Day, a tropical medicine researcher, explains Ebola is only spread through direct contact with blood, saliva and other bodily fluids. Since March, there have been more than 1,200 confirmed Ebola cases in West Africa. This is believed to be a new strain of the virus and nearly 700 of those infected in this worst-known outbreak have died.There is no known cure for Ebola. It was first recognized in Zaire (now the Democratic Republic of Congo) in 1976. There is no approved vaccine, but at least four are under development. Question: According to the passage, which of the following about Ebola virus is true? Yes or no, is the answer "It is only spread through direct contact with blood, saliva and other bodily fluids."?
**Answer**
No

Article: Plants may not have eyes and ears,but they can recognize their siblings ,and researchers at the University of Delaware have discovered how.The ID system lies in the roots and the chemical signals they secrete . Canadian researchers published that sea rocket,a common seashore plant,can recognize its siblings.Susan Dudley observed that when siblings are grown next to each other in the soil,they "play nice" and don't send out more roots to compete.However,the moment one of the plants is thrown in with strangers,it begins competing with them by rapidly growing more roots to take up the water and mineral nutrients in the soil. After reading Dudley's study,Bais decided to find the method behind the sibling recognition.Working in his laboratory,Bais and his doctoral student Meredith Biedrzycki set up a study with wild populations of Arabidopsis thaliana.In a series of experiments,young seedlings were exposed to liquid media containing the root secretions from siblings,from strangers,or only their own secretions.The length of the longest lateral root was measured.The exposure of plants to the root secretions of strangers induced greater lateral root formation than exposure of plants to sibling secretions.Strangers planted next to each other are often shorter,because so much of their energy is directed at root growth.Because siblings aren't competing against each other,their roots are often much shallower . Biedrzycki did the _ laboratory research,observing more than 3,000 plants involved in the study every day for seven continuous days and documenting the root patterns."Arabidopsis roots are nearly translucent when they are young and were also twisted when I removed them from plates,"Biedrzycki notes."This manuscript is very important for my research since the focus of my thesis project is understanding the biochemical ways behind root secretions." The research also may have implications for the home gardener."Often we'll put plants in the ground next to each other and when they don't do well,we blame the... Question: What encouraged Bais to study the sibling recognition? Yes or no, is the answer "Dudley's study."?
