Background: Earthquakes may take place every day near a volcano. But before an eruption, the number and size of earthquakes increases. This is the result of magma pushing upward into the magma chamber. This motion causes stresses on neighboring rock to build up. Eventually the ground shakes. A continuous string of earthquakes may indicate that a volcano is about to erupt. Scientists use seismographs to record the length and strength of each earthquake. Paragraph: Two neighboring cities are situated in a volcanic area with lots of earthquakes. Park city is situated near a very active volcano, while Hill city is situated 50 miles north. Given the paragraph above, please answer correctly the following question: Which city experiences more magma pushing upward into the magma chamber?
Ans: Park

Background: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis. Paragraph: Ben and Jerry were two friends with very different dietary habits. Jerry ate healthy food, and was always on top of his caloric consumption, while Ben overate because he loved fatty foods such as butter, bacon et al. Given the paragraph above, please answer correctly the following question: Which friend was at a lower risk for cardiovascular disease?
Ans: Jerry

Background: A major use for petroleum products is fuel for cars, trucks, airplanes, trains, and other vehicles. The chemical used are usually a mixture of compounds containing several carbon atoms in a chain. When the material is ignited, a massive amount of gas is created almost instantaneously. This increase in volume will move the pistons in an internal combustion engine to provide power. A jet plane works on a similar principle. Air comes into the front of the engine and mixes with the jet fuel. This mixture is ignited and the gases formed create a lot of pressure to push the plane forward. The idea can be seen even more clearly in the case of a rocket launch. The ignition of the fuel (either solid-state or liquid) creates gases produced under great pressure that pushes the rocket up. Paragraph: Two sister cities used petroleum products in different ways. Sin city used it for fuel, while Hill city used it only for making plastic materials which would then recycle. Given the paragraph above, please answer correctly the following question: Which city used more fuel for airplanes?
Ans: Sin

Background: The Figure below shows decibel levels of several different sounds. As decibel levels get higher, sound waves have greater intensity and sounds are louder. For every 10-decibel increase in the intensity of sound, loudness is 10 times greater. Therefore, a 30-decibel "quiet" room is 10 times louder than a 20-decibel whisper, and a 40-decibel light rainfall is 100 times louder than the whisper. High-decibel sounds are dangerous. They can damage the ears and cause loss of hearing. Paragraph: Jonathan is attending a football game for his favorite team. Before the game, there will be a fireworks display and a fly over by some jet fighter planes. Jonathan has been looking forward to the fireworks for weeks because he has heard they are really great. The fireworks begin and their sound waves are of a high intensity. After the fireworks, the jets fly over and the sound waves for that has an even higher intensity than the fireworks did. Given the paragraph above, please answer correctly the following question: Which sound more likely damaged Jonathan's ears?
Ans: jets
