Instead of going on location, producers can recreate the city's look in studios with the help of computers at lower cost. But San Francisco still attracts moviemakers, as its long history of film offers plenty of iconic  spots to visit. Here are just a few: Alcatraz: The Enforcer (1976), Escape From Alcatraz(1979), Murder in the  First (1995), The Rock (1996) A federal prison from 1934 to 1963, Alcatraz housed notorious criminals. Now a national park, Alcatraz offers visitors a chance to tour the prison, including a look at one of the cells portrayed in Clint Eastwood's Escape from Alcatraz, with the concrete chipped away behind the vent . Fort Point, Golden Gate Bridge: High Anxiety (1977), Foul Play (1978), The Presidio(1988), Dopamine(2003) Built to protect the San Francisco Bay area from attacks during the Civil War, Fort Point is where James Stewart saved Kim Novak in Vertigo, right at the base. The bridge has also been blown up countless times on films, including inX-Men:The last Stand (2006) andMonsters vs. Aliens(2009). The best view is from the north side, looking back to the city.    Coit Tower: The Enforcer, Inner Space(1987), The Presidio, Sister Act 2(1993),  The Rock, Dr. Dolittle (1998), Boys and Girls(2003)    The narrow white concrete column at the top of Telegraph Hill has been a part of San Francisco's skyline since 1933, and offers amazing views of the bay and the city. Coit Tower has been in the backdrop of numerous movies filmed in San Francisco.    City Hall: A view to a Kill(1985),Class Action(1991),Final Analysis(1992),Bedazzled(2000),The Wedding Planner(2001), Milk(2008)    City Hall has one of the largest domes in the world and it replaced a structure destroyed in the 1906 earthquake. It was used at the end of Invasion of the Body Snatchers, and Metro City Hall in the 2010 animated movie,Megamind, was an homage   to San Francisco's City Hall.

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Animals Can Sense Natural Disasters Among the dead in South Asia' s tsunami were many tourists at Sri Lanka' s national wildlife park at Yala. But very few of the park's animals -- elephants, buffaloes, monkeys and wild cats -- appear to have died. There are theories that animals can sense natural disasters and run away to safety. First, it's possible that the animals may have heard the quake before the tsunami hit. The underwater burst produced sound waves known as infrasound . Humans can't hear infrasound, but many animals including dogs, elephants, tigers and pigeons can. A second early warning sign the animals might have sensed is ground vibration . The great quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves moving on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached Sri Lanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yala might have felt the Rayleigh waves and then run to higher ground. But what about humans? While we can't hear infrasound, we can feel it, although we don't necessarily know we're feeling it. We also experience Rayleigh waves by special sensors in our joints , which exist just for that purpose. Sadly, it seems we don't pay attention to the information when we get it. Maybe we screen it out because there's so much going on before our eyes and in our ears. Options: A Rayleigh waves can be felt both by animals and human beings. B Rayleigh waves, just like infrasonic sound, can only be felt by animals. C Rayleigh waves are vibrational waves that usually cause quakes or tsunamis. D Rayleigh waves move on the ocean surface at a speed ten times that of sound waves. Answer: A Rayleigh waves can be felt both by animals and human beings. Question:
++++++++++
output: Which of the statements about "Rayleigh waves" is true?


Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Premier Win Jiabao continued his second trip around the quake disaster zone on May 23, 2008, visiting surviving students in Mianyang, one of the worst-hit cities. In a tent school, where more than 500 students from the destroyed prefix = st1 /BeichuanMiddle Schoolwere studying, Premier Wen encouraged them to study harder following the disaster. "let us not forget the earthquake," he told the students. "Then you will know what life is all about--it is bumpy, as the roads are.  Today, people save us and take good care of us. In the future, we will help them in return." He wrote on the blackboard to encourage them, "Hardships make a country stronger."

During the next four days, Premier Wen set foot in almost all of the worst-hit counties, walking over rocks and tiles, comforting weeping children and encouraging rescuers. The Chinese Premier says saving lives is the top priority. "We must try all means to get into those areas. The earlier, the better. One person can be saved one second earlier. As long as there is a gleam of hope, we will make efforts 100 times greater than that.' Chinese are deeply moved by what the Premier has said and done. A mother sent a message to her son in Beijing, saying "The 66-year-old Premier Wen has worked really hard for quake relief. He has comforted and moved us. Pass this on to your friends, pray for him." Options: A Hardships make a country stronger. B Premier Wen jiabao went on his first trip around the quake disaster zone. C Life is difficult. D The Chinese are deeply moved by Premier Wen. Answer: A Hardships make a country stronger. Question:
