input question: Background: The earliest members of the human species evolved around 200,000 years ago in Africa. Early humans lived in small populations of nomadic hunters and gatherers. Human beings remained in Africa until about 40,000 years ago. After that, they spread throughout Europe, Asia, and Australia. By 10,000 years ago, the first human beings colonized the Americas. During this long period of time, the total number of human beings increased very slowly. Birth rates were fairly high but so were death rates, producing low rates of population growth. Paragraph: Two colleagues studied human evolution, Dan studied early humans, from around 200,000 years ago, while Bob studied human settlements from 10,000 years ago. Given the paragraph above, please answer correctly the following question: Which student learned more about high birth rates????
output answer: Bob

input question: Background: Further heating then adds energy to the liquid particles, increasing their speed, kinetic energy, and temperature. This is the second slope on the curve. Once the particles are energetic enough to completely break free of each other, they start to enter the gas phase. Boiling occurs at the second plateau of this curve, and the temperature at this point is referred to as the boiling point . Again, the added heat is being used to break up the interactions between particles instead of increasing their kinetic energy, so no temperature increase is observed until all particles are in the gas phase. Finally, adding even more energy will further speed up the gas particles, increasing the kinetic energy and temperature of the substance. Paragraph: James is going camping and decides to really live the experience. He brings only his tent and essentials and sets out into the woods. After pitching camp he remembers he needs to secure water. Luckily there is a stream nearby so he fill s a pot with water and brings it back to his camp. He starts a fire, placing the pot on top of it so the water can boil Given the paragraph above, please answer correctly the following question: Will the particles in water move slower or faster after increasing their temperature????
output answer: faster

input question: Background: However, the addition of a metal catalyst, such as platinum, provides a lower energy pathway. The energy requirements for breaking the H-H bond are offset somewhat if each hydrogen atom can form a new bond with the metal surface. Then, collisions between the alkene and the metal-hydrogen complex result in the formation of a product. The metal surface is regenerated after the hydrogen atoms are removed, so it is not used up by the reaction, but it increases the rate by stabilizing the high energy hydrogen atoms. Paragraph: Michael and Robert are both performing a chemistry experiment. The reaction they are performing uses alkenes and hydrogen as reactants. Michael performs the experiment without any additional materials, while Robert performs the experiment while using a platinum catalyst. Given the paragraph above, please answer correctly the following question: Whose reaction will require more energy to occur????
output answer: Michael

input question: 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 fewer motion causing stresses on neighboring rock to build up????
output answer:
Hill
