input: Please answer the following: I can use this background: Many respiratory diseases are caused by pathogens. A pathogen is an organism that causes disease in another organism. Certain bacteria, viruses, and fungi are pathogens of the respiratory system. The common cold and flu are caused by viruses. The influenza virus that causes the flu is pictured below ( Figure below ). Tuberculosis, whooping cough, and acute bronchitis are caused by bacteria. The pathogens that cause colds, flu, and TB can be passed from person to person by coughing, sneezing, and spitting. Illnesses caused by bacteria can be treated with antibiotics. Those caused by viruses cannot. Now, I have a new situation: Martin and David are roommates in their dorm room. Martin comes down with the flu and is very sick coughing and sneezing a lot. David opts to take care of Martin, spending a lot of time with him to make sure he gets well soon. Answer this question please: Given David decides to stay with his parents instead of taking care of Mathew, will his chances of getting the flu increase or decrease?

output: decrease

input: Please answer the following: I can use this background: 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. Now, I have a new situation: Two neighboring ponds were stocked with adult fish last year. Hill pond had a very nice winter and the fish started reproducing normally, while Mound pond had no fish reproducing this spring. Answer this question please: Which pond had more fish spawning this spring?
++++++++++
output: Hill

input: Please answer the following: I can use this background: The jejunum is the second part of the small intestine, where most nutrients are absorbed into the blood. As shown in Figure below , the mucous membrane lining the jejunum is covered with millions of microscopic, fingerlike projections called villi (singular, villus). Villi contain many capillaries, and nutrients pass from the villi into the bloodstream through the capillaries. Because there are so many villi, they greatly increase the surface area for absorption. In fact, they make the inner surface of the small intestine as large as a tennis court! Now, I have a new situation: Pete liked the human physiology so he started reading about the digestive system, especially about the jejunum. His colleague Fox, studied more about the stomach. Answer this question please: Which student read more about where most nutrients are absorbed into the blood?
++++++++++
output: Pete

input: Please answer the following: I can use this background: When soil is flooded, hypoxia develops, as soil microorganisms consume oxygen faster than diffusion occurs. The presence of hypoxic soils is one of the defining characteristics of wetlands. Many wetland plants possess aerenchyma, and in some, such as water-lilies, there is mass flow of atmospheric air through leaves and rhizomes. There are many other chemical consequences of hypoxia. For example, nitrification is inhibited as low oxygen occurs and toxic compounds are formed, as anaerobic bacteria use nitrate, manganese, and sulfate as alternative electron acceptors. The reduction-oxidation potential of the rhizhosphere decreases and metal ions such as iron and manganese precipitate. Aerenchyma is a modification of the parenchyma. Now, I have a new situation: Owen inherited two pieces of land. The Eastern land was covered in wetlands, not very good for building or farming on it, but the Western land had a good rich soil good for agriculture. Answer this question please: Which land had hypoxia develop in the soil?
++++++++++
output:
Eastern
