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 didn't learn about the spread of humans to Europe?
Answer: team Alpha

Question: Given the background: Other pathogens spread when they get on objects or surfaces. A fungus may spread in this way. For example, you can pick up the fungus that causes athlete's foot by wearing shoes that an infected person has worn. You can also pick up this fungus from the floor of a public shower or other damp areas. After acne, athlete's foot is the most common skin disease in the United States. Therefore, the chance of coming in contact with the fungus in one of these ways is fairly high. and the situation: Bart and Homer decide to go bowling to celebrate the start of the weekend. Upon arriving, Bart needs to rent a pair of bowling shoes from the alley since he doesn't own any. Homer brought his own pair of bowling shoes though and doesn't need to rent a pair. They bowl for several hours until their arms are tired and they can hardly stand. Answer the following question: Who is more likely to develop athlete's foot?
Answer: Bart

Question: Given the background: The temperature of a body of water directly affects the amount of dissolved oxygen it can hold. Following Henry's law, as water becomes warmer, oxygen becomes less soluble in it. This property leads to daily anoxic cycles on small geographic scales and seasonal cycles of anoxia on the larger scale. Thus, bodies of water are more vulnerable to anoxic conditions during warmest period of the day and during the summer months. This problem can be further exacerbated in the vicinity of industrial discharge where warm water used to cool machinery is less able to hold oxygen than the basin to which it is released. and the situation: Dan visited Twin lakes every year. The interesting fact about them wast that, while Twin I had a very cold water all year, Twin II lake had very warm waters year round. Answer the following question: Which body of water held less dissolved oxygen?
Answer:
Twin II
