Problem: Given the question: Write a multi-choice question for the following article: Article: Everybody hates it, but everybody does it. A recent report said that 40%of Americans hate tipping. In America alone, tipping is a $16 billion-a-year industry. Consumers acting politely ought not to pay more than they have to for a given service. Tips should not exist. So why do they? The common opinion in the past was that tips both rewarded the efforts of good service and reduced uncomfortable feelings of inequality. And also, tipping makes for closer relations. It went without saying that the better the service, the bigger the tip. But according to a new research from Cornell University, tips no longer serve any useful function. The paper analyzes numbers they got from 2,547 groups dining at 20 different restaurants. The connection between larger tips and better service was very weak. Only a tiny part of the size of the tip had anything to do with the quality of service. Tipping is better explained, by culture than by the money people spend. In America, the custom came into being a long time ago. It is regarded as part of the accepted cost of a service. In New York restaurants, failing to tip at least l5% could well mean dissatisfaction from the customers. Hairdressers can expect to get l5%-20%, and the man who delivers your fast food $2. In Europe, tipping is less common. In many restaurants the amount of tip is decided by a standard service charge. In many Asian countries, tipping has never really caught on at all. Only a few have really taken to tipping. According to Michael Lynn, the Cornell papers' author, countries in which people are more social or outgoing tend to tip more. Tipping may reduce anxiety about being served by strangers. And Mr. Lynn says, "In America, where people are expressive and eager to mix up with others, tipping is about social approval. If you tip badly, people think less of you. Tipping well is a chance to show off."

Problem: Given the question: Write a multi-choice question for the following article: Article: Boiler rooms are often dirty and steamy,but this one is clean and cool.Fox Point is a very new 47unit living building in South Bronx,one of the city's poorest areas.Twothirds of the people living there are formerly homeless people,whose rent is paid by the government.The rest are lowincome families.The boiler room has special equipment,which produces energy for electricity and heat.It reuses heat that would otherwise be lost to the air,reducing carbon emissions while also cutting costs. Fox Point is operated by Palladia,a group that specializes in providing housing and services to needy people.Palladia received support from Enterprise Community Partners (ECP),which helps build affordable housing by providing support to housing developers. ECP has created national standards for healthy,environmentally clever and affordable homes which are called the Green Communities Standards.These standards include water keeping,energy saving and the use of environmentally friendly building materials.Meeting the standards increases housing construction costs by 2%,which is rapidly paid back by lower running costs.Even the positioning of a window to get most daylight can help save energy. Michael Bloomberg,New York's mayor,plans to create 165,000 affordable housing units for 500,000 New Yorkers.Almost 80% of New York City's greenhouse gas emissions come from buildings,and 40% of those are caused by housing.So he recently announced that the city's Department of Housing and Preservation and Development (DHPD),whose duty is to develop and keep the city's supply of affordable housing,will require all its new projects to follow ECP's green standards. Similar measures have been taken by other cities,such as Cleveland and Denver,but New York's DHPD is the largest city developer of affordable housing in the country.(2010*,B)

Problem: Given the question: Write a multi-choice question for the following article: Article: In June, 2007, a group of students from eight high schools in Winnipeg, the capital of Canada's Manitoba province, will begin test-launching a satellite the size of a Rubik's cube. The one-kilogram Win-Cub satellite, named for its home city and its shape, will be put into low orbit. Once in space, it can perform for a few months or up to several years, communicating information that could help find the signs of earthquakes. There are 80 similar satellite projects worldwide, but this is the first high-school based program of its kind in Canada. 30 Manitoba high school students are having a hand in designing and building the satellite, in cooperation with aerospace experts and 10 students from the University of Manitoba, and with support from two other organizations. The Win-Cube project is not something that goes on a piece of paper; it is real-world engineering, allowing high school students to have an opportunity to learn more about the exciting world of engineering through their participation in this challenging program. It is also taken as a wonderful example of the unique partnerships within Manitoba. Designing, building and launching a satellite with high-school participation will bring this world-class educational project into reality and Manitoba closer to space. "These Manitoba high school students deserve congratulations for their enthusiasm, innovation , and a strong love for discovery," said Education, Citizenship and Youth Minister Peter Bjomson. "We want to make science more relevant, interesting and attractive to high school students by showing them how classroom studies can relate to practical experience in the workplace or, in this case, in space," Bjomson added. The Win-Cube program is mainly aimed at inspiring a strong desire for discovery on the part of the students. It also shows Manitoba's devotion to research and innovation and the development of a skilled workforce -- all important drivers of knowledge-based economic growth.
