Read the following article and select the best answer. Article: "Dr.Papaderos, what is the meaning of life?" The usual laughter followed, and people stirred to go.Dr.Papaderos held up his hands and stilled the room and looked at me for a long time, asking with his eyes if I was serious and seeing from my eyes that I was. "I will answer your question." Taking his wallet out of his hip pocket, he fished into a leather wallet and brought out a very small round mirror, about the size of a quarter.And what he said went like this: "When I was a small child during the war, we were very poor and we lived in a remote village.One day, on the road, I found the broken pieces of a mirror.A German motorcycle had been broken in that place. I tried to find all the pieces and put them together, but it was not possible, so I kept only the largest piece.This one.and, by scratching it on a stone, I made it round.I began to play with it as a toy and became fascinated by the fact that I could reflect light into dark places where the sun would never shine--n deep holes and crevices and dark closets.It became a game for me to get light into the most inaccessible places I could find. I kept the little mirror, and, as I went about my growing up, I would take it out in spare time and continue the challenge of the game.As I became a man, I got to understand that this was not just a child's game but a metaphor for what I might do with my life.I came to understand that I was not the light or the source of light.But light--truth, understanding, knowledge--is there, and it will shine in many dark places only if I reflect it. I am a fragment of a mirror whose whole design and shape I do not know.Nevertheless, with what I have I can reflect light into the dark places of this world--into the black places in the hearts of men--and change some things in some people.Perhaps others may see and do likewise.This is what I am talking about.This is the meaning of my life. Question: On hearing the author's question, Dr.Papaderos _ at first. - laughed at his foolishness - wasn't sure of the answer - doubted his seriousness - wasn't interested at all
doubted his seriousness

Read the following article and select the best answer. 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: We can infer from the passage _ . - the new technique can be widely used in the operations - the new technique needs to be further tested - the new technique has more benefits than risks - any new technique has risks
the new technique needs to be further tested

*Question*
Read the following article and select the best answer. 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? - The Tile needs to be charged after a year of use. - One smart phone can only be linked up with one Tile. - A missing item can't be found if it goes out of your phone's Bluetooth range. - The Tile cannot be linked up with a phone without Bluetooth.
**Answer**
The Tile cannot be linked up with a phone without Bluetooth.
