Problem: Write a multi-choice question for the following article: Article: Forget chip fat, sugar cane or rapeseed oil -- the latest source of biofuel could be watermelons. Scientists have discovered that the fruit is a great source of sugar that can be readily distilled into alcohol to power cars and farm machinery. And sellers reject 360,000 tons of "substandard" fruit every year in America alone which could be used as an economical way to make fuel. The waste from US growers could produce nearly two million gallons (nine million litres) of biofuel per year. In the study, researchers at the United States Department of Agriculture set out to determine the biofuel potential of juice from rejected watermelons --those not sold due to imperfections, and currently ploughed back into the field. About a fifth of each yearly watermelon crop is left in the field because of surface blemishes or because they are misshapen. Dr. Wayne Fish, who led the team, found that 50 percent of the fruit was fermentable into alcohol which could provide valuable fuel. "We've shown that the juice of these watermelons is a source of readily fermentable sugars, representing an unexploited raw material for alcohol biofuel production," he said. The study, published in the journal Biotechnology for Biofuels, discovered that watermelons could produce around 20 gallons of fuel per acre from fruit that otherwise would go to waste. Production of biofuels has been targeted by Western governments as a way to support renewable energy targets. The European Union has a target for 2010 that 5.75 percent of transport fuels should come from biological sources, but the target is unlikely to be met. The British government's Renewable Transport Fuel Obligation requires five percent of the fuel sold at the pump by 2010 to be biofuel.

A: Question: We can infer from the passage that _ .Options:A it will cost a lot to make biofuel from watermelonsB Western countries are engaged in biofuel study but still have a long way to goC watermelon juice has been used as a source of sugars to produce alcohol biofuelD the European Union is likely to meet its target of transport fuels from biological sourcesAnswer:B

Problem: Write a multi-choice question for the following article: Article: The United States is not part of the Kyoto Protocol.But since 2005 more than 1,000 mayors across the country have agreed to sign their own version of the protocol. It is called the United States Conference of Mayors' Climate Protection Agreement.Local leaders have agreed to follow the suggestions of the Kyoto Protocol in their communities.They have also agreed to urge state and federal governments to follow these suggestions.One goal is to reduce air pollution to the 1990 levels by 2012. A "green" city might work on several kinds of environmental goals and programs.These include air quality,reducing electricity use, green building, public health, the reuse of materials, water quality and clean transportation. The Natural Resources Defense Council works to protect the environment through action, law and science.One of its online projects is called Smarter Cities, which lists some cities that have made important environmental steps. Washington,D.C.is also a leading city for green roofs,with over 92,000 square meters of green rooftops.The city also launched a program called "Skip the Bag,Save the River."Stores charge people a fivecent tax for using plastic or paper shopping bags instead of reusable bags.Money from the tax will be used to clean up a local river. New York City is using water as a renewable energy source.For several years, the city has experimented with water in the East River to create energy.Officials operating the program recently asked for permission to put into place 30 river turbine devices. The people of Portland, Oregon are among the top recyclers in the nation.People living there recycle over half of the waste they throw out.The city has also worked to provide green transportation by providing safe bike paths and free parking spaces where electric cars can get recharged. In Oakland, California, you can ride on one of several public hydrogenpowered buses.These buses release zero pollution into the air.However,they cost about five times more than common buses.

A:
Question: Why are shoppers charged a fivecent tax for buying shopping bags?Options:A To clean a local lake that has been polluted.B To get enough money for the green roof project.C To prevent shoppers from using reusable bags.D To collect money for an environmental project.Answer:D
