input: Please answer the following: Background: The dangers of global warming are being increasingly studied by a wide global consortium of scientists. These scientists are increasingly concerned about the potential long-term effects of global warming on our natural environment and on the planet. Of particular concern is how climate change and global warming caused by anthropogenic, or human-made releases of greenhouse gases, most notably carbon dioxide, can act interactively, and have adverse effects upon the planet, its natural environment and humans' existence. It is clear the planet is warming, and warming rapidly. This is due to the greenhouse effect, which is caused by greenhouse gases, which trap heat inside the Earth's atmosphere because of their more complex molecular structure which allows them to vibrate and in turn trap heat and release it back towards the Earth. This warming is also responsible for the extinction of natural habitats, which in turn leads to a reduction in wildlife population.The most recent report from the Intergovernmental Panel on Climate Change (the group of the leading climate scientists in the world) concluded that the earth will warm anywhere from 2.7 to almost 11 degrees Fahrenheit (1.5 to 6 degrees Celsius) between 1990 and 2100. Paragraph: Rob was evaluating two research studies on climate change, study A and study B. Study A explained how increased greenhouse gases would affect the climate. On the other hand, study B showed how decreased greenhouse gases would affect the climate. Rob found the studies very interesting. Given the paragraph above, please answer correctly the following question: Which study involved more complex molecules, study A or study B?
++++++++++
output: study A

input: Please answer the following: Background: When using measuring devices, we often use a technique called calibration to increase the accuracy of our measurements. Calibration is a method of setting or correcting a measuring device by matching it to known measurement standards. To better understand calibration, we will look at the example of calibrating a thermometer. All thermometers are slightly different in their temperature readings. One way to calibrate a thermometer is by using the freezing point and boiling point of water ( Figure below ). If we know that water freezes at 0C and boils at 100C, we can calibrate our thermometer by measuring the temperature of ice water and of boiling water. We place the thermometer in ice water and wait for the thermometer liquid to reach a stable height, then place a mark at this height which represents 0C. Then we place the thermometer in boiling water, and after waiting for the thermometer liquid to reach a stable height, we place a mark at this height which represents 100C. We can then place 100 equally spaced divisions between our 0 and 100C marks to each represent 1C. Our thermometer has now been calibrated using the known values for the freezing point and boiling point of water, and can be used to measure temperatures of objects between 0 and 100C. Paragraph: While working on a touch screen laptop, Chris notices that his button presses seem to not be connecting where he presses on the screen. He opens up a calibration application and resets everything. The program then asks him to touch the screen where a button is in different locations on the screen. Given the paragraph above, please answer correctly the following question: Will properly running the calibration application likely increase or decrease the accuracy of Chris' touch screen?
++++++++++
output: increase

input: Please answer the following: Background: Plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". This occurs in a type of glacier called a "valley glacier". As a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock. The freezing and thawing action of the ice enlarges, widens, or causes further cracks in the bedrock as it changes volume across the ice/water phase transition (a form of hydraulic wedging), gradually loosening the rock between the joints. This produces large pieces of rock called joint blocks. Eventually these joint blocks come loose and become trapped in the glacier. Paragraph: Rob likes to visit high mountainous locations. Last year he visited the the Alps mountains in Austria. There he saw an unique type of glacier called valley glacier. This year he went further east to visit the Ural mountains in Russia. There he didn't see any valley glacier. Given the paragraph above, please answer correctly the following question: Where there would be joint blocks, Alps or Ural?
++++++++++
output: Alps

input: Please answer the following: Background: As a cell grows, its volume increases more quickly than its surface area. If a cell was to get very large, the small surface area would not allow enough nutrients to enter the cell quickly enough for the cell's needs. This idea is explained in Figure below . However, large cells have a way of dealing with some size challenges. Big cells, such as some white blood cells, often grow more nuclei so that they can supply enough proteins and RNA for the cell's requirements. Large, metabolically active cells often have lots of cell protrusions, resulting in many folds throughout the membrane. These folds increase the surface area available for transport of materials into or out of the cell. Such cell types are found lining your small intestine, where they absorb nutrients from your food through protrusions called microvilli . Paragraph: Gary, a high school student, is supposed to be studying two different cells under a microscope during his biology class. Gary doesn't like biology class at all though and can't find the motivation to look at the cells in detail. In his homework where students are supposed to write what they observed, Gary simply wrote down the first thing he saw under the microscope which was that Cell A is larger than cell B. It won't get him a great grade, but Gary is hoping it will at least get him a pass on the assignment. Given the paragraph above, please answer correctly the following question: Will Cell B have an easier or harder time transporting materials than cell A?
++++++++++
output:
harder
