Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Farmer Ed Rawlings smiles as he looks at his orange trees. The young oranges are growing well in Florida's weather. Warm sunshine and gentle rains, along with Ed Rawlings' expert care, will produce a good crop of oranges this year. However, Ed has to guard against Florida's changeable winter weather. In January and February, temperatures can destroy Ed's entire orange crop. Having farmed in Florida for the past 35 years, Ed is prepared for the frost . When temperatures drop below freezing, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer of ice around the trees. Strange as it may sound, this thin layer of ice actually keeps the fruit warm. What happens is simple. When the trees are watered, the water loses heat and becomes ice. The warmth of the heat it loses is taken in by the fruit and keeps its temperature at a safe level. Ed has effectively used this method to save many orange crops. But Ed still faces difficulties. The trees must be watered at the exact moment the temperature drops to the freezing point. Also, just the right quantity of water must be used. Too much water can form a thicker layer of ice that will break the tree's branches . Another difficulty is that wind blows away the heat, so Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used. Computer technology may help Ed with some of these worries. With equipment , air and soil temperatures and wind speed can be measured. The information is fed into a computer which can calculate when the temperature will drop below freezing. The computer can correctly decide the quantity of water to be used and how frequently( ) the trees should be watered. Ed finds looking after his orange trees a lot easier with the help of a computer, and, his customers will have the benefits of computer--age oranges. Options: A using a wind machine to drive away the cold air B equipping his orange trees with a computer C watering it at the proper time D picking his fruit at the first sign of frost Answer: C watering it at the proper time Question:

A: Ed tries to protect his crop by _ .

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: This past month saw one of the most devastating storms in history brings death and destruction on the Philippines. The number of lives lost is still being calculated, but it is already sitting above five thousand. In the flurryof news about the storm and its after-math, the cries of "I told you so" from environmentalists rang out loud and clear. These scientists were especially vocal during the United Nations Climate Change Conference, which just wrapped up in Warsaw, Poland. The timing of the conference and Typhoon Haiyan was an eerie coincidence, but perhaps the concurrence offered a wakeup call for all. Christiana Figures, Executive Secretary of the UN Framework Convention on Climate Change (UNFCCC) said, "We are witnessing ever more frequent extreme weather events, and the poor and vulnerable are already paying the price." Scientists claim that storms like Typhoon Haiyan are an inevitable result of the effect greenhouse gases are having on our environment. Environmental analysts claim that rising temperatures around the globe and changing weather patterns are all part of the same problem. This isn't breaking news. We've heard the warnings for years. The UN has been hosting the Climate Change Conference since1995.But the changes that need to be made are huge. Added to this, the developed nations and developing countries have competing interests that are difficult to settle. The issue of who takes responsibility becomes difficult to resolve. We may feel far away from Poland and resolving conflicts between countries, but we mustn't feel far away from the issue. When we watch neighboring countries suffer in severe weather, when we hear reports of increasing global temperatures, when we walk outside and find it difficult to breathe the Shanghai air, we know we have a very real problem. So what are we going to do about it? Are we making every-day choices that can have a positive impact? Are we reducing our carbon footprint? Are we choosing to walk, ride a bicycle or take public transportation instead of a car?... Options: A Haiyan B Bebinca C Danas D Cimaron Answer: A Haiyan Question:

A: What is the most terrible typhoon in 2013? It is _ .
