Not all of your navigational skills are learned.Research shows that your sense of direction is innate.An innate ability is something you are born with.Your brain has special navigational neurons--head-direction cells, place cells, and grid cells --and they help program your inside compass when you're just a baby. In 2010.scientists carried out an experiment to study baby rates' activity in their brains.Although the rats were newborns.the researchers discovered that their head-direction cells(which help them recognize the direction they're facing) were fully grown and developed.The rats.it seemed.were born with a sense of direction.And they hadn't even opened their eyes yet! Humans.of course, are not rats.But the hippocampus --the brain we use for navigation--is similar in most mammals.If the rat's compass develops this way.then it's likely a human's compass does, too. If we're born with a sense of direction.then why are some people so good at getting lost? The scientists found that the two other cells---place and grid cells--developed within the first month.Place cells are thought to help us form a map in our mind.while gird cells help us navigate new and unfamiliar places.The two cells work together, and that's where the trouble might be. People who took part in a 2013 study played a video game that required them to travel quickly between different places.Monitoring their brains.the scientists.According to researcher Michael Kahana, differences in how gird cells work may help explain why some people have a better sense of direction than others. Question: What do we know about our navigational neurons? Yes or no, is the answer "Place and grid cells grow later than head-direction cells"?
No

Q: Article: People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020. In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races. Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer. "By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. " Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved. ks5u Question: According to Richard Mason, what is the biggest challenge for driverless cars? Yes or no, is the answer "They are now too expensive for consumers."?
A: No

Article: I came to live here where I am now between Wounded Knee Greek and Grass Greek. Others came too, and we made these little grey houses of logs that you see, and they are square. It is a bad way to live, for there can be no power in a square. You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything tries to be round. In the old days when we were strong and happy people, all our power came to us from the respectful circle of the nation, and so long as the circle was unbroken, the people were getting rich. The flowering tree was the living center of the circle, and the circle of the four quarters nursed it. The east gave peace and light, the south gave warmth, the west gave rain, and the north with its cold and strong wind gave strength and continuous power. This knowledge came to us from the outer world with our brief. Everything the Power of the World does is done in a circle. The sky is round, and I have heard that the earth is round like a ball, and so are all the stars. Birds make their nests in circle, for theirs are the same as ours. The sun comes forth and goes down again in a circle. The moon does the same, and both are round. Even the seasons form a great circle in their changing, and always come back again to where they were. The life of a man is a circle from childhood to childhood, and so it is in everything where power moves. Our places were like the nests of birds, and these were always set in a circle, the nation's circle, a nest of many nests, where the Great Spirit meant for us to nurse our children. But the "white people" have put us in these square boxes. Our power is gone and we are dying, for the power is not in us any more. You can look at our boys and see how it is with us. Where we were living by the power of the circle in the way we should, boys were men at twelve or thirteen years of age. But now it takes them very much longer to grow up. Question: According to the passage, the Indians _ . Yes or no, is the answer "lived in round places, but were forced to live in square houses"?

No
