user: TASK DEFINITION: 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.
PROBLEM: Background Paragraph: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. They are more likely to bump into one another and to collide with greater force. For example, when you fry an egg, turning up the heat causes the egg to cook faster. The same principle explains why storing food in a cold refrigerator reduces the rate at which food spoils (see Figure below ). Both food frying and food spoiling are chemical reactions that happen faster at higher temperatures. 
Story: Ned learned about reactions at a higher temperature for his physics class, while Paul had to learn about reactions at lower temperatures. 
Question: Which person didn't study about the heat causing the egg to cook faster?

SOLUTION: Paul.

PROBLEM: Background Paragraph: Something that is elastic can return to its original shape after being stretched or compressed. This property is called elasticity . As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force . The farther the material is stretched or compressed, the greater the elastic force becomes. As soon as the stretching or compressing force is released, elastic force causes the material to spring back to its original shape. You can watch a demonstration of elastic force at this URL:. 
Story: Andy is playing with a rubber band. He stretches the rubber band out as far as he can without breaking it. 
Question: Will the amount of force required to stretch the rubber band increase or decrease as he stretched it further?

SOLUTION: increase.

PROBLEM: Background Paragraph: Plates include both oceanic crust and continental crust. Stable subduction zones involve the oceanic lithosphere of one plate sliding beneath the continental or oceanic lithosphere of another plate due to the higher density of the oceanic lithosphere. That is, the subducted lithosphere is always oceanic while the overriding lithosphere may or may not be oceanic. Subduction zones are sites that usually have a high rate of volcanism and earthquakes.[2][better source needed] Furthermore, subduction zones develop belts of deformation and metamorphism in the subducting crust, whose exhumation is part of orogeny and also leads to mountain building in addition to collisional thickening. 
Story: David is interested in geology. One day he was studying about how the earth's crust works. He specifically noticed two lithosphere, lithosphere A an lithosphere B. Lithosphere A is an oceanic lithosphere while lithosphere B is an overriding lithosphere. He also noticed two 
distinct zones, zone A an zone B. Zone A is a subduction zone, but zone B is not a subduction zone. Just reading about geology made David excited. Now, he wants to 
visit places with high volcanic activity. For that he chose place C. To compare with place C geology he would also visit place D, which does not have any volcanic activity. 
Question: Which place would most likely be in zone B, place C or place D?

SOLUTION:

assistant: place D.
