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: Bernoulli’s law explains how the wings of both airplanes and birds create lift that allows flight (see Figure below ). The shape of the wings causes air to flow more quickly — and air pressure to be lower — above the wings than below them. This allows the wings to lift the plane or bird above the ground against the pull of gravity. A spoiler on a race car, like the one in Figure below , works in the opposite way. Its shape causes air to flow more slowly — and air pressure to be greater — above the spoiler than below it. As a result, air pressure pushes the car downward, giving its wheels better traction on the track. 
Story: Rob is experimenting with how air pressure works. To that end, he has designed two tests. In the first test the air flow works as it would in an airplane wing. He labels it as case A. In the second test the air flow works as it would in a race car spoiler. He labels it as case B. He is surprised to see that air flow behaves differently in different situations. 
Question: Would case A have faster or slower air flow above it than case B?

SOLUTION: faster.

PROBLEM: Background Paragraph: When peer feedback is established it allows students to interact with their peers and creates high social skills while learning material more effectively. Interaction with other students allows students to have better social approaches when interacting. Learning by peer feedback gives students more of an opportunity to work as a unit instead of individuals working alone. Working in groups gives students more useful life skill that well help prepare them for the future. Peer feedback gives more control to the student, the student can decide if they want to use the criticism their peers are giving them or not. When given options more students are more likely to give and absorb more feedback. Peer feedback has confirmed an increase in affect; students that have increasing responsibilities have more drive towards their work and a spike in confidence.[6] Furthermore, Kristanto (2018) found that peer feedback is an essential element of peer assessment. In peer assessment, feedback from peers can provide suggestions or correction for students' future works as companion of the received grade.[7]. 
Story: Two college groups did a one year experiment on each other. One group called Group Alpha spend more time and worked together. Group Beta let it's members study on their own and be less dependent on the group. Group Alpha had better results. 
Question: Which group experienced less peer feedback?

SOLUTION: Beta.

PROBLEM: Background Paragraph: When you go to the dentist to get a tooth pulled, you really don’t want to feel any pain. The dentist injects an anesthetic into your gum and it eventually becomes numb. One theory as to why anesthetics work deals with the movement of ions across the cell membrane. The anesthetic gets into the membrane structure and causes shifts in how ions move across the membrane. If ion movement is disrupted, nerve impulses will not be transmitted and you will not sense pain – at least not until the anesthetic wears off. 
Story: Two men in the Vietnam War needed to have their arms amputated. Unfortunately, the men were not able to be knocked unconscious for the operation. The doctor asked each patient if they wanted anesthetic injected into their arm or not. Marco replied that he wanted some, and Luke declined any anesthetic. 
Question: Which person's ions will be able to move across the cell membrane?

SOLUTION:
Luke.
