Problem: Given the question: I read this background article the other day: Fish reproduce sexually. They lay eggs that can be fertilized either inside or outside of the body. In most fish, the eggs develop outside of the mother's body. In the majority of these species, fertilization also takes place outside the mother's body. The male and female fish release their gametes into the surrounding water, where fertilization occurs. Female fish release very high numbers of eggs to increase the chances of fertilization.  I am facing a new situation today: Tim and Dan both studied reproduction in college. Dan studied plant reproduction while Tim studied fish reproduction.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person studied less about the ways fish eggs can be fertilized?
++++++++++++++++++++++++++++++++
The answer is:
Dan

input question: I read this background article the other day: During the Cold War, the Arctic became a place where the United States, Canada, and the Soviet Union performed significant research that has been essential to the study of climate change in recent years. A major reason why research in the Arctic is essential for the study of climate change is because the effects of climate change will be felt more quickly and more drastically in higher latitudes of the world as above average temperatures are predicted for Northwest Canada and Alaska. From an anthropological point of view, researchers study the native Inuit peoples of Alaska as they have become extremely accustomed to adapting to ecological and climate variability.[1]  I am facing a new situation today: Two countries situated at different latitudes are exposed to climate change. Iceland is located closer to the North Pole, while Ecuador is located near the Equator.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country will feel the effects of climate change less quickly????
output answer: Ecuador

I read this background article the other day: Compared to conventional milk production, organic milk production tends to have lower eutrophication potential per ton of milk or per hectare of farmland, because it potentially reduces leaching of nitrates (NO3−) and phosphates (PO4−) due to lower fertilizer application rates. Because organic milk production reduces pesticides utilization, it increases land use per ton of milk due to decreased crop yields per hectare. Mainly due to the lower level of concentrates given to cows in organic herds, organic dairy farms generally produce less milk per cow than conventional dairy farms. Because of the increased use of roughage and the, on-average, lower milk production level per cow, some research has connected organic milk production with increases in the emission of methane.Animal welfare issues vary among dairy farms and are not necessarily related to the way of producing milk (organically or conventionally).  I am facing a new situation today: There are two dairy farms in the town of Milkton and both are about the same size. Farm A produces only organic milk. Farm B does not but they are considering switching production to organic milk.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farm uses more pesticides, dairy farm A or B?
----
Answer: B

Q: I read this background article the other day: During May, June, and July, the Northern Hemisphere is exposed to more direct sunlight because the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to seasonal lag, June, July, and August are the warmest months in the Northern Hemisphere while December, January, and February are the warmest months in the Southern Hemisphere.  I am facing a new situation today: Two twin brothers live far away from each other. Dan lives in the Norther Hemisphere, in North America, and Bill lives in Tasmania, in the Southern Hemisphere.They often talk about the weather, the seasons, and how it affects them.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother experiences less sunlight in May?
A: Bill

Question: I read this background article the other day: Any unused energy in food—whether it comes from carbohydrates, proteins, or lipids—is 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.  I am facing a new situation today: Roger and Samantha are brother and sister. Both of them perform roughly the same amount of physical activity on a day-to-day basis. Roger, however, eats a lot more food relative to the amount he needs given his activity levels. Samantha, on the other hand, eats the appropriate amount of food given her level of activity.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who is more likely to develop hypertension in the future?
Answer: Roger

Please answer this: I read this background article the other day: Once again, a mutation is the change in the DNA or RNA sequence. In multicellular organisms, mutations can be subdivided into germline mutations and somatic mutations. Germline mutations occur in the DNA of sex cells, or gametes, and are therefore potentially very serious. These mutations can be passed to the next generation. If the zygote contains the mutation, every cell in the resulting organism will have that mutation. If the mutation results in a disease phenotype, the mutation causes what is called a hereditary disease. Somatic mutations , which occur in somatic, or body, cells, cannot be passed to the next generation (offspring). Mutations present in a somatic cell of an organism will be present (by DNA replication and mitosis) in all descendants of that cell. If the mutation is present in a gene that is not used in that cell type, the mutation may have no effect. On the other hand, the mutation may lead to a serious medical condition such as cancer.  I am facing a new situation today: Dan studied multicellular organisms that presented mutations. Group A presented gemline mutations, while group B presented somatic mutations. He was fascinated by these organisms.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group had fewer organisms having mutations in the DNA of sex cells?
++++++++
Answer:
group B
