input question: Given the background: The earliest members of the human species evolved around 200,000 years ago in Africa. Early humans lived in small populations of nomadic hunters and gatherers. Human beings remained in Africa until about 40,000 years ago. After that, they spread throughout Europe, Asia, and Australia. By 10,000 years ago, the first human beings colonized the Americas. During this long period of time, the total number of human beings increased very slowly. Birth rates were fairly high but so were death rates, producing low rates of population growth. and the situation: Research team Alpha learned about early human activities, from 200000 years ago, while team Gamma learned about late human activities, 40000 years ago to present times. Answer the following question: Which team learned about humans that lived in small populations of nomadic hunters????
output answer: team Alpha

input question: Given the background: Surface temperature differences in turn cause pressure differences. A hot surface warms the air above it causing it to expand and lower the density and the resulting surface air pressure. The resulting horizontal pressure gradient moves the air from higher to lower pressure regions, creating a wind, and the Earth's rotation then causes deflection of this air flow due to the Coriolis effect. The simple systems thus formed can then display emergent behaviour to produce more complex systems and thus other weather phenomena. Large scale examples include the Hadley cell while a smaller scale example would be coastal breezes. and the situation: Mark was visiting southern Africa as an exchange student. He was amazed by the beauty of Namib Desert, which is located mostly in Namibia. He kind of enjoyed the hot surface of the desert. Next to Namib desert is the grasslands of Botswana. He noticed that the surface temperature was much lower there. Answer the following question: Which place would have higher surface air pressure, Namibia or Botswana????
output answer: Botswana

input question: Given the background: Many different chemical substances cause cancer. Dozens of chemicals in tobacco smoke, including nicotine, have been shown to cause cancer ( Figure below ). In fact, tobacco smoke is one of the main sources of chemical carcinogens. Smoking tobacco increases the risk of cancer of the lung, mouth, throat, and bladder. Using smokeless tobacco can also cause cancer. Other chemicals that cause cancer include asbestos, formaldehyde, benzene, cadmium, and nickel. and the situation: Linda lives in a run down house in downtown Detroit. The walls and floors are degraded, and were made with large amounts of asbestos. As a result, Linda comes into contact with asbestos frequently. Linda's cousin, Gerald, lives in a upper-class neighborhood of Detroit. His house was built recently, and as a result he never comes into contact with asbestos. Answer the following question: Who is less likely to develop cancer????
output answer: Gerald

input question: Given the background: Any unused energy in foodwhether it comes from carbohydrates, proteins, or lipidsis stored in the body as fat. An extra 3,500 Calories of energy results in the storage of almost half a kilogram (1 pound) of stored body fat. People who consistently consume more food energy then they need may become obese. Obesity occurs when the body mass index is 30.0 kg/m 2 or greater. Body mass index (BMI) is an estimate of the fat content of the body. It is calculated by dividing a person's weight (in kilograms) by the square of the person's height (in meters). Obesity increases the risk of health problems such as type 2 diabetes and hypertension. and the situation: Two groups of adults were a part of a diet experiment. Group Brown ate 3500 extra calories a day for 3 months, while group Yellow, had a normal diet. Group Brown gained a lot of weight. Answer the following question: Which group has a smaller chance of getting more health problems????
output answer:
Yellow
