Question: Write a multi-choice question for the following article, with the given choices and answer: Article: The Golden Gate Bridge in San Francisco, California is one of the world's most beautiful bridges. It is also one of the most visited places in the world. Vehicles cross the bridge an average of 41 million times each year. More than 1,800 hundred million vehicles have used the bridge since it opened more than 70 years ago. The bridge was painted "International Orange" because that color went well with the natural surroundings. The color also is easier to see in the heavy fog that often covers the area. But the Golden Gate Bridge was not named for its orange color. It was named for the body of water that it crosses, the Golden Gate Strait. The Golden Gate Strait is the entrance to the San Francisco Bay from the Pacific Ocean. The Golden Gate Bridge links the city of San Francisco with Marin County,California. Planning for the bridge began in the 1920s when the area around San Francisco was growing. People living in the area needed another way to get to the city besides small ferries . Joseph Strauss was the chief engineer for the project. Work began in 1934. Mr.Strauss demanded the strongest safety protections in the history of bridge building. These included the first use of "hard hats" to protect the workers' heads and special glasses to protect their eyes. A special safety net was suspended under the bridge. This net saved the lives of 19 men during the construction. However, 11 other workers were killed when they fell from the bridge through the net. Still, this was a new safety record for the time. The Golden Gate Bridge opened in 1937. It extends 1,280 meters across the water. The total length is 2,737 meters. It was the largest suspension bridge in the world until 1964. That is when the Verrazano Narrows Bridge opened in New York City. Today, the Golden Gate Bridge is the ninth longest suspension bridge in the world. Options: A He attached importance to the workers' safety. B His safety measures were not of practical value. C He built the first suspension bridge in the world. D He demanded strong measures to ensure the safety of the bridge. Answer: A He attached importance to the workers' safety. Question:
Answer: What do we know about Joseph Strauss?

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Geologists have been studying volcanoes for a long time.Though they have learned a great deal,they still have not discovered the cause of volcanic action.They know that the inside of the earth is very hot,but they are not sure exactly what causes the great heat.Some geologists have thought that the heat is caused by the great pressure of the earth's outer layers.Or the heat may be left from the time when the earth was formed.During the last sixty years scientists have learned about radium,uranium,thorium,and other radioactive elements.Many scientists now believe that much of the heat inside the earth is produced by radioactive elements. Whatever the cause of the heat may be,we do know that the earth gets hotter the farther down we dig.In deep mines and oil wells the temperatures rise about 1degF for every 50 feet.At this rate of the temperature 40 miles below the earth's surface should be over 4 000deg.This is much hotter than necessary to melt rock.However,the pressure of the rock above keeps most materials from melting at their usual melting points.Geologists believe that the rock deep in the earth may be plastic,or puttylike .In other words,the rock yields slowly to pressure but is not liquid.But if some change in the earth's crust releases the pressure,the rock melts.Then the hot,liquid rock can move up toward the surface. Options: A the pressure of the rock itself B the pressure of the rock above C the pressure of the earth's outer layers D the heat given out by some radioactive elements Answer: B the pressure of the rock above Question:
Answer: According to the passage, _ prevents most rock from melting at its usual melting points.

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: How much do you hate waiting for another beer in a crowded bar? Josh Goodman invented a pretty obvious solution --self-service beer taps. Goodman, 36, recalled the exact moment in late 2008 when his frustration _ "I was hanging out with my friends at a Baltimore sports bar before an Orioles game," he said. "We just couldn't get another beer served to us quickly." Even more than annoyed, Goodman was struck by how much money the bar must be losing. Almost immediately, he got to work on a self-service beer concept. Within a few months, Goodman had launched Pour My Beer in Chicago (where he'd relocated to be with his wife). He invested $20,000 of his own funds and partnered with a U.S. manufacturer to make beer tables with two to four self-service taps. In February 2009, Goodman landed his first client : A Baltimore tavern. He spent the next two years growing the business and adding more bars and restaurants. In 2011, Pour My Beer introduced self-service "beer walls," which let people pour their own beer from taps on a wall. Pour My Beer has expanded to over 200 restaurants and bars in 28 states and Canada. The concept will roll out in Chicago's O'Hare International Airport this week and in Italy and Brazil later this year. The tables start at $4,000 and the beer walls cost as much as $16,000. It generated more than $400,000 in sales in 2013 and doubled that in 2014. Goodman expects to take in close to $2 million in revenue this year(2015) --which would make it the company's first profitable year. "Our business customers tell us that they've cut down on waste and they're selling twice as much beer on average," said Goodman. Options: A His friends advised him to do so. B He realized the loss in waiting for beers. C He set up Pour My Beer in Chicago. D His company started to make profits. Answer: B He realized the loss in waiting for beers. Question:
Answer:
Josh Goodman decided to invent the self-service beer taps when _ .
