Article: It takes years of school to develop math skills, but learning about numbers starts earlier than you might think. Now according to a new study, at three months, babies have already started acquiring a concept   of "how much". Previous research had suggested that very young babies can tell when the number of objects   in a group has changed. But the babies in these studies were simply reacting generally to the fact that something had changed, they suspected. Researchers of Harvard University studied 36 babies, all three months old. During the tests, each baby wore a hat with sensors  . The babies watched a series of images on a computer screen. _ showed the same object, such as a cartoon character. For a while, the number of the objects in the pictures didn't change. Then the images began to display a different object, or a different number of one of the objects the babies had previously looked at. As soon as something changed, the babies' brains responded with a specific pattern of electrical signals, which would be recorded by sensors. By analyzing these signals, the researchers discovered that one part of the brain (near the top on the left side) responded when the object in the image changed. A different part of the brain (lower and on the right side) responded when the number of objects in the image changed. This was not the area of the brain that is involved in attention. That suggests that the babies' brains are doing more than just reacting to a change in what they're seeing - they actually seem to be able to tell number changes from other types of changes. Numbers and amounts are important concepts in our lives. Even though babies are years away from adding, subtracting  , multiplying, and dividing, their brains seem to be preparing for a time when they finally will. Question: Why were hats with sensors used in the study? Yes or no, is the answer "To record the electrical activity of each baby's brain."?

Yes

Article: Jerry Morris died on 28 October 2009. He was 99 years old. You have probably never heard of him. He was a professor of public health. More than 50 years ago he produced one of the most famous epidemiological   papers of the 20th century. His study showed that bus conductors were much less likely to die of heart disease than bus drivers. Why? Because the conductors spent their working day walking. It seems obvious now but in the middle of the last century doctors were puzzled by the rising numbers of people who got heart diseases. Jerry Morris found one of the main causes: a sedentary   lifestyle. He started exercising for a few minutes each day and lived until his 100th year. If you wish to protect your heart, you have to do more than wander in the garden. The exercise needs to be reasonable. Jogging is not for everyone and a round trip to the gym takes a couple of hours, plus the monthly membership fee is only good value if you visit regularly. The answer is simple: walk. A half-hour purposeful walk five times a week will lower your risk of heart disease, diabetes and strokes. Older people sometimes feel they have left it too late. But it is never too late to start and there are no upper age limits. Start gently. Take your time: a 15-minute flat walk in the nearest park, four or five times a week. Within a month or so, you are already beginning to protect your heart. Build the walks up. When you can comfortably walk for half an hour in the park, go further: try following rivers and canals. Regular walkers have their own natural gymnasium. There is no membership fee, just some of the finest scenery in the world. Great Britain is the walker's gym. When you have followed the rivers and canals, and are enjoying walking for a couple of hours, head for the coast. Once again, build it up slowly. When you are comfortable with long coastal walks, you can think of our national parks. Question: What might be the best title for this passage? Yes or no, is the answer "A Walk a Day Keeps the Doctors away"?
**Answer**
No

Article: The Celerifere, an early version of the bicycle, was built around 1791 by a French man, Comte Mede de Sivrac. It was basically a scooter with a high seat. There were no pedals---you had to push with your feet like you do with a skateboard or a scooter. Around 1816 Baron Karl Drais de Sauerbrun in Germany added a moveable steering handle. These early machines were often known as dandy horses or hobby horses, but weren't very popular. The improvement that made them popular was added by a Scottish blacksmith around 1839. Kirkpatrick Macmillan added pedals to enable it to get up hills. It was this improvement that made the bicycle a serious form of transportation. Bike were called velocipedes or bone-shakers, because of the lack of the proper tires made for a rough ride! It wasn't until around 1869 that they began to be called bicycles ("two-wheels"). Carriage makers in Paris (either Pierre and Ernest Michaux, or their employee Pierre Lallement) switched the pedal to the front wheel. That's why it is usually either Lallement or the Michauxs, not Macmillan, who are considered as the inventor of the bicycle. In 1869 the penny-farthing or high-wheeler was invented. With the large wheel the rider could go much farther with each push of the pedal, but caused many accidents because the seat was so far off the ground. In the mid-1880s Englishman James Starley manufactured what he called the "safety bicycle" , which had two similarly-sized wheels and a major improvement--- a chain and sprocket  driven rear wheel, with the pedals between the two wheels like modern bicycles. One more historical note---it's possible that the idea of the bicycle was thought of almost 400 years before it was actually invented. There is a drawing of a bicycle-like machine in one of Leonardo da Vinci's notebooks, which dates back to about 1493. Question: Who is recognized as the inventor of the bicycle? Yes or no, is the answer "The Michauxs."?
