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.

Input: Consider Input: Background Paragraph: Antifreeze could also be called “antiboil” because it also raises the boiling point of the water in a car radiator. Hot weather combined with a hot engine can easily raise the temperature of the water in the radiator above 100 °C, which is the boiling point of pure water. If the water boils, it could cause the engine to overheat and become seriously damaged. However, if antifreeze has been added to the water, the boiling point is much higher. For example a 50 percent antifreeze solution has a boiling point of 129 °C. Unless the water gets hotter than this, it won’t boil and ruin the engine. 
Story: Rob is an auto mechanic. He was checking the radiators of his car and truck. He put antifreeze into the car radiator, but didn't put any antifreeze into the truck radiator. He was wondering how the vehicles would fare in coming hot weather. 
Question: Which vehicle's engine would less likely be damaged, car or truck?

Output: car.


Input: Consider Input: Background Paragraph: Common causes of heat exhaustion include:[1]

Hot, sunny, humid weather
Physical exertion, especially in hot, humid weather
Due to impaired thermoregulation, elderly people and infants can get serious heat illness even at rest, if the weather outside is hot and humid, and they are not getting enough cool air.
Some drugs, such as diuretics, antihistamines, beta-blockers, alcohol, ecstasy, and amphetamines can cause an increase in the risk of heat exhaustion.[2]
Especially during physical exertion, risk factors for heat exhaustion include:[1]

Wearing dark, padded, or insulated clothing; hats; and/or helmets (for example, football pads or turnout gear)
Having a higher percentage of body fat
Dehydration
Fever
Some medications, like beta blockers and antipsychotic medicines[2]. 
Story: Two groups of people were out in the sunny, humid weather of Illinois. Group One wore black clothes and helmets, and Group Two wore white, light clothing. Both groups were comprised of people of all ages and fitness levels and exercised in the sun for an hour. 
Question: Which group had more inebriated people experiencing heat illness?

Output: Group One.


Input: Consider Input: Background Paragraph: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth’s surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465°C (860°F). That’s hot enough to melt lead!. 
Story: Brad and Joe studied atmospheric conditions on different planets of our solar system. Joe studied about Earth, while Brad studied more about Venus. 
Question: Which person learned less about sulfuric acid clouds?


Output: Joe.
