Article: John Wesley Powell(1834--1902)Was a famous explorer of the American West.When he Was young,his mother put him under the guidance of George Crookham,a self-taught scientist,from whom he received a wide,but informal,education.Young John learned many things about the natural sciences.But his father preferred him to study religion.The argument continued for three years.Then John decided to leave home to seek further education.He soon discovered that he knew more about science than any teacher he met.He realized that the only good scientific education in the country came from colleges in the east,like Harvard and Yale.But he Was too poor to go to them,SO he got work as a school teacher in Illinois.Whenever possible,he went on scientific trips of his own. In 1861,civil war broke out in the United States.John joined the Union forces of the North.At the battle of Shiloh Powell lost his right arm.Despite his disability, he began his famous exploration of the Colorado River on May 24 1869. It Was one of the greatest trips of discovery in the history of America.Never before had any white men traveled to that area.The trip Was far more dangerous than expected.The rivers were filled with rocky areas and waterfalls.Sometimes,the boats overturned or broke into pieces against big rocks.All along the way, Powell measured distances,temperatures,heights,depths and currents.He examined soils,rocks and plant life.Powell'S explorations led to the creation of US Geological Survey, which became responsible for all mapping and scientific programs of American lands. Powell's scientific studies of western lands shaped his ideas of how those lands should be used.He suggested programs to control both crop farming and cattle raising.He Was especially concerned about water supplies.Many of his ideas were rejected at first and were not signed into law until years after his death because they were far ahead of his time. Question: From the text we can see that _ . Yes or no, is the answer "Powell'S explorations caused the creation of US Geological Survey"?
No

Article: Japanese doctors have used thin sheets of tissue from people's cheeks repair damaged corneas . A team from Osaka University transplanted thin layers of cheek cells onto the eyes of four patients with a rare and painful eye condition,reports BBC online. Patients whose vision had been cloudy could see well afterwards,and the"new corneas"remained clear more than a year after the operation. Doctors can also take cells from a healthy eye and grow them in a dish to produce a new cornea,or they can transplant corneas from donors . But these techniques may not work when both eyes are too badly damaged by accident or disease. The team hope their work may help solve the problem and lead to other types of grow-your-own tissue transplants. The cornea is the clear layer of cells on the surface of the eye. It can be damaged by trauma or by a range of diseases. The team worked with four patients who had a painful condition that causes cloudy corneas and dry eyes. Often the eye can regenerate cornea cells but none of the four patients had this ability. The researchers took a 3 mm-wide square of tissue from inside the mouth(cheeks)and grew it into a thin layer in the lab. They used a special low temperature technique to separate a very thin sheet off each batch. They then laid that onto the patient's eye. The cell layers stuck onto the eye and developed into tissue that looked and acted like a healthy cornea. However,long-term follow-up and experience with a large series of patients is needed to assess the benefits and risks this method. Yet,"it does offer the potential of treating severe eye diseases that are resistant to standard approaches,"said the head of the research,Kohji Nishida. Question: If both eyes are too badly damaged,we can treat them _ . Yes or no, is the answer "by none of the mentioned method"?
No

Q: Article: Once upon a time, there was a family with eighteen children in a small village not far from Nuremberg. Eighteen! In spite of the hopeless condition, two of the children had a dream. They both wanted to pursue their talent for art. After many long discussions, the two boys finally worked out an agreement. They would toss a coin. The loser would go down into the nearby mines and, with his earnings, support his brother who attended the academy. Then, when that brother who won the toss completed his studies, in four years, he would support the other brother at the academy. They tossed a coin on a Sunday morning after church. Albrecht Durer won and went off to Nuremberg. Albert went down into the dangerous mines and, for the next four years, financed his brother, whose work at the academy was excellent. By the time he graduated, he had earned considerable fees for his works. When the young artist returned to his village, the Durer family held a festive dinner to celebrate Albrecht's triumphant homecoming, where Albrecht drank a toast to his beloved brother for the years of sacrifice that had enabled him to fulfill his ambition. His closing words were, "Now you can go to Nuremberg to look for your dream, and I will take care of you." Tears streaming down his pale face, shaking his lowered head from side to side, Albert sobbed, "No... no... no...no. It is too late for me. Look...look at what four years in the mines has done to my hands! I have been suffering from arthritis so badly in my right hand that I cannot even hold a glass to return your toast, much less draw delicate lines with a pen or a brush... For me, it is too late." To show thanks to Albert for all that he had sacrificed, Albrecht Durer painstakingly drew his brother's abused hands with palms together and thin fingers stretched skyward. He called his powerful drawing simply "Hands", but the entire world almost immediately opened their hearts to his great masterpiece and renamed it "The Praying Hands". The next time you... Question: Which of the following is NOT true about Albrecht Durer? Yes or no, is the answer "He didn't begin to earn his living until his graduation."?
A: No

Article: Do you often lose things? Don't worry. Now a new tool that can be connected to any object you might lose may be the way to solve your problem. The Tile, a small square linked up to your iphone or ipad by means of Bluetooth, lets you see how close you are to your missing item, within a 50-to-150-foot range. If the item goes out of your phone's 150-foot range, it can still be found on other smart phones with the same app. When you drive the app on your phone, it shows you, with green bars that increase or decrease, how close or far away you are from the Tile. You can also program it to make a sound when you get close to the Tile. And you can link up your phone with up to ten Tiles. And if your lost object--a dog, for example, or a stolen bike--go out of your own phone's 150-foot Bluetooth range, you can set it as a "lost item". If any of the phones with the Tile app comes within range of your lost item, a message will be sent to your phone, telling you its position. The Tile app also has the function to remember where it last saw your Tile, so that you can easily find where you left it. Since the Tiles use Bluetooth rather than GPS, they are never out of battery or needn't to be charged, and they work for one year before needing to be replaced. And the app works with all generations of iPhones and iPads. For further information, please visit www. tile666.com. Question: Which of the following is TRUE according to the passage? Yes or no, is the answer "The Tile cannot be linked up with a phone without Bluetooth."?
**Answer**
No
