You are given a background paragraph that describes one or more causal or qualitative relationships such as a relationship in economics or a scientific law and a story that makes use of the concepts or the relationship described in the provided paragraph. You are also given a question about the story that requires an understanding of the relationship described in the background paragraph and the story. You need to come up with an answer to the given question; the answer will be a span from either the question or the story. In order to correctly answer the given question, you need to understand the relationship mentioned in the background paragraph and should be able to use it to understand that in the story. Your answer can not consist of any word that is not mentioned in any of these: the background paragraph, the story, or the question. You can directly copy and paste a span from the story or the question while answering the given question.

Background Paragraph: Enzymes increase the rate of chemical reactions by reducing the amount of activation energy needed for reactants to start reacting. One way this can happen is modeled in the Figure below . Enzymes aren’t changed or used up in the reactions they catalyze, so they can be used to speed up the same reaction over and over again. Each enzyme is highly specific for the particular reaction is catalyzes, so enzymes are very effective. A reaction that would take many years to occur without its enzyme might occur in a split second with the enzyme. Enzymes are also very efficient, so waste products rarely form. 
Story: A scientist is testing chemical reactions. At first he tries mixing two chemicals together at a temperature of 85 degrees Celsius and labels it Trial A. He records the time for the reaction to complete at 2 minutes. Knowing that this isn't the temperature users at home will be combining the chemicals at he tries the reaction again at a more modest 65 degrees Celsius and labels this trial B. Noting this temperature the reaction takes almost 4 times as long which is completely unacceptable, He then gets an idea to add and enzyme designed specifically for these two chemicals and then tries the reaction at the modest 65 degrees Celsius again calling this one trial C. 
Question: Given that this enzyme is designed specifically for use with the chemicals in this experiment, will the reaction for trial C be faster or slower than the reaction in trial B?

Ex Output:
faster.

Background Paragraph: New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe’s neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks. 
Story: Pam and Jill studied mammals. Jill was fascinated with their nutrition, while Pam was more interested and read about the natural selection phenomenon. 
Question: Which person studied more about organisms with traits that better enable them to adapt to their environment?

Ex Output:
Pam.

Background Paragraph: Precipitation in grasslands is equal to or less than evapotranspiration and causes soil development to operate in relative drought. Leaching and migration of weathering products is therefore decreased. Large amounts of evaporation causes buildup of calcium (Ca) and other large cations flocculate clay minerals and fulvic acids in the upper soil profile. Impermeable clay limits downward percolation of water and fulvic acids, reducing chemical weathering and podzolization. The depth to the maximum concentration of clay increases in areas of increased precipitation and leaching. When leaching is decreased, the Ca precipitates as calcite (CaCO3) in the lower soil levels, a layer known as caliche. 
Story: Monsoon plays a big role in shaping local climates. In some places of the Horn of Africa monsoon causes heavy rainfall. But across the Red Sea the Arabian Peninsula mostly misses the monsoon. As a result, they have minimal rainfall throughout the year. 
Question: Would less or more calcite precipitate in the lower soil levels in Horn of Africa than in Arabian Peninsula?

Ex Output:

less.
