[单项选择]In the world of art, distinguishing the authentic piece from the forgery is not an easy feat and often requires the use of multiple experts. Millions of dollars can be at stake, yet even experts can be fooled. However, a recent discovery has introduced a new resource for galleries and other groups seeking to establish the origins of their paintings: mathematicians. Math experts were able to analyze digital images of authenticated paintings where they found consistent differences in paint texture. This consistency suggests that each artist has a unique style of brush stroke that cannot be completely duplicated.

One of the most famous bridges in the world is the Golden Gate Bridge that spans San Francisco Bay. Because it was built in 1937, it has become one of the first sights people see if they are coming to San Francisco by ship. The main part of the Golden Gate Bridge is a suspension span. It hangs from steel cables that are supported by two huge towers, one at each end of the bridge. The suspension span was the longest in the world when it was finished in 1937. It measures 4,200 feet between the towers. The floor of the
bridge is wide enough for six lanes of cars, three in each direction. There are sidewalks, too, but not many people use them. It costs a lot of time to go on foot from one end of the bridge to the other.
