input: Please answer the following: Given the background: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species. and the situation: Two students from the same class, studies different types of animals. Bill studied predators, while John studied grazers. Answer the following question: Which student found out that a single species could become dominant over others?
++++++++++
output: Bill

input: Please answer the following: Given the background: Collision theory tells us that molecules need to collide in order for a reaction to take place. All else being equal, anything that increases the frequency of collisions would also increase the rate of reaction. One way to do this is to increase the concentrations of one or more of the reactants. Using a real world example, a busy freeway will experience much more frequent car collisions than a fairly empty neighborhood street. Similarly, forcing more randomly moving molecules into the same amount of space will cause an increased number of collisions over a given length of time, providing the reactants with more opportunities to transform into products. and the situation: Becky is an accountant who as a hobby enjoys performing amateur chemistry experiments at home. She is currently working with a new idea she found online and is curious to see the results. She has two beakers, beaker A and beaker B, filled with the same chemical compound. She was able to find a reactant at a store and is going to pour some into each of the beakers. Her plan is to pour twice as much into beaker B and write down her observations. Answer the following question: Which beaker will have a lower rate of reaction?
++++++++++
output: beaker A

input: Please answer the following: Given the background: Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in - ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane, with two carbon atoms. The chemical formulas and properties of methane, ethane, and several other alkanes are listed in Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally have higher boiling and melting points. and the situation: Ian is learning about alkanes in science class and their melting and boiling points. He is given a few different alkanes try try with this test, mainly methane ethane and a third alkane that he has to test to find out what it is called Alkane C. Answer the following question: Which has a lower boiling/melting point, Methane or Ethane?
++++++++++
output: Methane

input: Please answer the following: Given the background: The Hawaiian Islands ( Figure above ) are in the central Pacific Ocean. The islands are volcanoes that increase in age from southeast to northwest. The youngest island is the Big Island of Hawaii at the southeast end of the chain. The volcanoes get older through Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai, and Niihau Islands through the northwest. The Kilauea volcano on Hawaii has been erupting almost continuously since 1983. There are also eruptions at an underwater volcano called Loih and the situation: Melinda lived on The Big Island of Hawaii. One day she invited her Australian friend Janice over to visit the islands. Janice was very excited about the invitation. Answer the following question: Which person lived closer to Kahoolawe island?
++++++++++
output:
Melinda
