user: Problem: Given the question: Please answer correctly the following question related to the paragraph below.   In which stage the gas molecules would collide more forcefully with the interior surface of the cylinder, stage A or stage B?  Rob is testing the properties of gas. To that end, he experimented with a cylinder of gas in three stages, stage A, stage B, and stage C. In stage A he kept the gas in room temperature. In stage B he heated the gas up. And in stage C he cooled the gas down.  Hint: Shown in the Figure below is a cylinder of gas on the left that is at room temperature (300 K). On the right, the cylinder has been heated until the Kelvin temperature has doubled to 600 K. The kinetic energy of the gas molecules increases, so collisions with the walls of the container are now more forceful than they were before. As a result, the pressure of the gas doubles. Decreasing the temperature would have the opposite effect, and the pressure of an enclosed gas would decrease.

The answer is:
stage B


Problem: Given the question: Please answer correctly the following question related to the paragraph below.   In which location the Geiger counter would click, location A or location C?  Keith landed a job with the EPA. As part of his training he needed to learn how the Geiger counter works. To learn more about the counter he tested it in three different locations, location A, location B, and location C. Location A had very high radiation; location B had low radiation; and location C didn't have any radiation. Keith learned how the counter works in locations with varying degrees of radiation.  Hint: You generally can’t see, smell, taste, hear, or feel radiation. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one pictured in the Figure below , contains atoms of a gas that is ionized if it encounters radiation. When this happens, the gas atoms change to ions that can carry an electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. You can see a video about the Geiger counter and how it was invented at the URL below.

The answer is:
location A


Problem: Given the question: Please answer correctly the following question related to the paragraph below.   Which team studied more about muscles performing lactic acid fermentation during strenuous exercise?  A group of students in biology class studied fermentation. Team A studied alcoholic fermentation, while team B learned more about lactic fermentation. They later organised a trivia contest between teams.  Hint: Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy.
