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.

[EX Q]: Background Paragraph: Alcoholic beverages do not make the entire body warmer.[361] The reason that alcoholic drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood. This can actually result in making the core body temperature lower, as it allows for easier heat exchange with a cold external environment. 
Story: Two people got stuck in a local  blizzard. Tom had a bottle of alcohol with him and drank it after he found some kind of shelter in the snow. Dan didn't have alcohol with him. 
Question: Which of the two people had a larger influx of warm blood near the surface of the skin?
[EX A]: Tom.

[EX Q]: Background Paragraph: For comparison,  sunlight on Saturn is slightly brighter than Earth sunlight at the average sunset or sunrise (see daylight for comparison table). Even on Pluto, the sunlight would still be bright enough to almost match the average living room. To see sunlight as dim as full moonlight on Earth, a distance of about 500 AU (~69 light-hours) is needed; there are only a handful of objects in the Solar System known to orbit farther than such a distance, among them 90377 Sedna and (87269) 2000 OO67. 
Story: A startup has build a simple spaceship that uses only sunlight for its propulsion. The more sunlight it gets faster it moves. They planned to send the spaceship to three different points, point A, point B, and point C. Point A is near the planet Saturn, point B is near Pluto, and point C is about 69 light-hours away. 
Question: At which point the spaceship would move faster, point B or point C?
[EX A]: point B.

[EX Q]: 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: Whose nerve impulses will not be transmitted?
[EX A]:
Marco.
