Problem: Write a multi-choice question for the following article: Article: SAN FRANCISCO--A phone app in San Francisco gives information about open parking spots.City officials in San Francisco introduced the app to try to reduce traffic jams in the city, but some say it raises safety concerns. In this city, drivers searching for parking spots lead to 30 percent of all downtown jams, city officials think.Now San Francisco has found a solution -- a phone app for spot-seekers that shows information about areas with available spaces.The system, introduced last month, relies on wireless sensors fixed in streets and city garages that can tell within seconds if a spot has opened up. But the system could come with serious consequences.Some people say that drivers searching for parking could end up focusing on their phones, not the road."It could be really distracting ," said Daniel Simons, a professor of psychology at the University of Illinois. City officials admitted the hidden problem.They are urging drivers to pull over before they use the city's iPhone app, or to do so before they leave home. Nathaniel Ford, executive director of the San Francisco Municipal Transportation Agency, said safety could actually improve if drivers quickly found a spot instead of circling and getting frustrated. San Francisco has put sensors into 7,000 parking spots and 12,250 spots in city garages.If spaces in an area open up, the sensors communicate wirelessly with computers that in turn make the information available to app users within a minute, said Mr. Ford, of the transportation agency.On the app, a map shows which blocks have lots of places(blue)and which are full(red). More than 12,000 people have downloaded San Francisco's app, which is available now only for the iPhone.

A: Question: The phone app mentioned in the text _ .Options:A is a bit slow in reactingB hasn't been put into serviceC was introduced several years agoD can't be downloaded to all phonesAnswer:D

When a couple goes out for an anm dinner,for example,the thought of feeling superior to others probably never comes to them. The goal is to share a special meal that stands out from other meals. There are no obvious limits to the _ of demand for quality.For example ,porsche famous car producer,has a model which was considered perhaps the best sport car on the mark Priced at over $120,000,it handles perfectly well and has great speen acceleration.But in 200 the producer introduced some changes which made the model slightly better in handling acceleration.People who really care about cars find these small improvemenmts exciting.To them,however,they must pay almost four times the price. By placing the desire to be superior to other at the heart of his description of nisation demands,Keynes actually reduced such demands.However,the desire for higher quality has natural limits.

[Q]: Write a multi-choice question for the following article: Article: You are seeing a film in which two men are having a fight. They hit one another over the heads with chairs. And so it goes on until one of the men crashes through a window and falls thirty feet to the ground below. He is dead! Of course he isn't really dead. With any luck he isn't even hurt. Why? Because the men who fall out of high windows or jump from fast moving trains, who crash cars or even catch fire, are professionals. They do this for a living. These men are called stuntmen. That is to say, they perform tricks. They actually do most of the things you see on the screen. For example, they fall from a high building. However, they do not fall onto hard ground but onto empty cardboard boxes covered with a mattress. Again, when they hit one another with chairs, the chairs are made of soft wood and when they crash through windows, the glass is made of sugar! But although their work depends on tricks of this sort, it also requires a high degree of skill and training. Often a stuntman's success depends on careful timing. For example, when he is " blown up" in a battle scene, he has to jump out of the way of the explosion just at the right moment. Naturally stuntmen are well paid for their work, but they lead dangerous lives. They sometimes get seriously injured, and even killed. A Norwegian stuntman, for example, skied over the edge of a cliff a thousand feet high. His parachute ( ) failed to open and he was killed. In spite of all the risks, this is no longer a profession for men only. Men no longer dress up as women to perform some dangerous actions. For nowadays there are stunt girls , too.
