Problem: Given the question: Background: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution, acid rain, and global warming. Fossil fuels are also limited and may eventually run out. Like fossil fuels, radioactive elements are limited. In fact, they are relatively rare, so they could run out sooner rather than later. On the other hand, nuclear fission does not release air pollution or cause the other environmental problems associated with burning fossil fuels. This is the major advantage of using nuclear fission as a source of energy. Paragraph: Us and Canada are two friendly countries. Canada uses alternative methods to produce electricity while the US use more coal and oil. Both countries recently participated in a Global Warming Council. Given the paragraph above, please answer correctly the following question: Which country burns more fossil fuels?
++++++++++++++++++++++++++++++++
The answer is:
US

Problem: Given the question: Background: Generally, nearsightedness first occurs in school-age children. There is some evidence that myopia is inherited. If one or both of your parents need glasses, there is an increased chance that you will too. Individuals who spend a lot of time reading, working or playing at a computer, or doing other close visual work may also be more likely to develop nearsightedness. Because the eye continues to grow during childhood, myopia typically progresses until about age 20. However, nearsightedness may also develop in adults due to visual stress or health conditions such as diabetes. A common sign of nearsightedness is difficulty seeing distant objects like a movie screen or the TV, or the whiteboard or chalkboard in school. Paragraph: David is a doctor with the local hospital. Yesterday, he was seeing two patients, patient A and patient B. His tests found out that patient A had myopia, but patient B had normal eyesight. He referred the patient with eye condition to an ophthalmologist. Given the paragraph above, please answer correctly the following question: Would patient A find it difficult or easier to see the whiteboard in school than patient B?
++++++++++++++++++++++++++++++++
The answer is:
difficult

Problem: Given the question: Background: People protect areas that might flood with dams. In dire situations, they use sandbags ( Figure below ). Dams are usually very effective, but high water levels sometimes cause a dam to break. In that case, flooding can be catastrophic. Flood waters can also overflow a dam. People may line a river bank with levees to protect against floods. These are high walls that keep the stream within its banks during floods. Flood protection in one location sometimes causes problems elsewhere. For example, a levee in one location may just force the high water upstream or downstream. This will lead to flooding in a different location. Sometimes water gets so high that the river must be allowed to flood. Paragraph: Two villages experienced flooding this spring. Berg village used many sandbags to protect from the dam overflowing. Creek village didn't use any sandbags, they were caught by surprise. Given the paragraph above, please answer correctly the following question: Which village experienced higher water levels?
++++++++++++++++++++++++++++++++
The answer is:
Creek
