Article: Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water,you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are full of black surfaces already, in the form of asphalt roads? Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside. The heat-collector is a system of connected water pipes. Most of them run from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the groun. When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes itunderground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer into which heat several heat exchangers have been built. The hot water from the street runs through these exchangers, warming the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store. In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice. Question: For what purpose are the diving pipes used? Yes or no, is the answer "To carry heat down below the surface."?
Yes

Article: Ears are for hearing -- everyone knows that. But for a creature called the Cuvier's beaked whale, hearing starts in the throat, a new study found. The observation might help explain how all whales hear. The work might also help scientists understand how animals are affected by underwater sonar . This sonar, used by some ships, sends out sound waves to locate underwater objects. The Cuvier's beaked whale is a so-called toothed whale. Toothed whales dive deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to "see" the shape, size, and location of objects, even when they're 1,000 meters under the sea, where it is totally dark. To better understand how the whale hears, researchers from San Diego State University in California took X-rays of two Cuvier's beaked whales. The whales had died and washed up on the beach. Ted Cranford and his colleagues used the images to make a computer model of a Cuvier's beaked whale's head. Then, they modeled the process of sound traveling through the head. The researchers knew that some sounds get to the ears of a toothed whale through a structure called "the window for sound". Found on the lower jaw, this structure is very thin on the outside and has a large pad of fat on the inside. When the researchers used their computer model to work out how sound waves travel in the whale's head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal's jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal's ears. Cranford guesses that other types of whales may hear through their throats. Further testing is needed to be sure. Eventually, the insight into how whales hear might explain whether sonar testing by military ships is causing the animals to wind up on beaches. Question: Researchers took X-rays of two Cuvier's beaked whales in order to _ . Yes or no, is the answer "know more about the way the whale hears"?

No

Ques: Article: A 12-year old boy who donated bone marrow to his dying sister and has raised more thanPS10,000 for charity has been named the UK's Family Hero of the Year. Adam Kerr, 12, from Armagh, Northern Ireland, also helps his mother care for his younger brother Brian, 9, who suffers from the genetic disease Fanconi's anaemia . But it is not the first hardship that has affected young Adam. When he was just six, he donated his own bone marrow to his younger sister Helen who suffered from a rare blood disorder. Sadly she developed complications and died a few months after the operation in 2005. Adam found it very difficult to be happy after Helen's death. So he decided to start raising money in memory of Helen to help local poor children and families with bereavement . Overall he has raised PS10,000 and he has no intentions of giving up. He organised a Fun Day to provide the money for a brother and sister from Northern Ireland to visit their sick brother having a bone marrow transplant in a London hospital. He received his award and a cheque forPS2,000 at an "Oscar's style" ceremony in London. Ms Phillips said: "Adam is an incredible young man. In his relatively short life he has faced real sadness and bad luck and yet he works tirelessly to make life better for others." The Awards were sponsored by the charity 4Children and Take a Break Magazine. Anne Longfield OBE, Chief Executive of 4Children said:"It's an honour to recognise Adam's devotion and self-sacrifice, and his bravery shows there is always reason for hope and optimism. There is so much unrecognized goodwill out there of people who do so much for others, and the inspiring winners of the Family Heroes Awards remind us how important it is for us all to do our best to make a difference in the lives of others." Question: What's the best title for the passage? Yes or no, is the answer "A little boy makes a big difference to others"?
Ans: No
