Teacher: Now, understand the problem? Solve this instance: Article: In front of a popular restaurant, a line of customers wait for taxis. And wait. Most of the cabs(taxis) are full. That's nothing unusual in this city of 4 million people. But it's 2:30 in the morning. Visitors to the Olympic Games may leave disappointed if they see Athens only through the eyes of the typical tourist, who makes a beeline of the islands after the visit to the Acropolis and the unusual and attractive Plaka district. To fully appreciate and discover Athens' many charms , do as the Greeks do: walk out into the neighborhoods, find the packed nightclubs, eat at one of the innumerable restaurants, or see Hollywood stars under real stars in a romantic outdoor cinema. The Greek capital is named for the ancient goddess Athena, whose favourite animal was the owl . It's a fitting symbol for the city's nocturnal nature, which often reaches its highest point in summer with a rush hour just before dawn. As native Athenian Panos Demestiha said, Athens by day is unlivable , but it's magical at night. Athenians face up to heavy traffic block, decreasing green space, dusty streets... City officials are using the momentum of the August 13-29 Olympics to fix some of these problems and make city life more bearable.
