Q: You are given a new situation: Two cousins both have chronic viral infections. Tim has Kaposi's sarcoma-associated herpesvirus, while Nate has the EpsteinBarr virus. and a hint : Hepatitis viruses can develop into a chronic viral infection that leads to liver cancer. Infection by human T-lymphotropic virus can lead to tropical spastic paraparesis and adult T-cell leukaemia. Human papillomaviruses are an established cause of cancers of cervix, skin, anus, and penis. Within the Herpesviridae, Kaposi's sarcoma-associated herpesvirus causes Kaposi's sarcoma and body-cavity lymphoma, and EpsteinBarr virus causes Burkitt's lymphoma, Hodgkin's lymphoma, B lymphoproliferative disorder, and nasopharyngeal carcinoma. Merkel cell polyomavirus closely related to SV40 and mouse polyomaviruses that have been used as animal models for cancer viruses for over 50 years. Please answer this question : Which cousin has a lower chance of developing Kaposi's sarcoma?
A: Nate

Q: You are given a new situation: Jimbo and Jedd are both farmers who have lakes and water wells downstream from their farms. Jimbo's products have been in high demand recently, so he has started to use very high amounts of fertilizers on his farms. Jedd has recently decreased the amount of fertilizer he uses because his products aren't wanted as much by the people in his town. and a hint : Huge amounts of chemicals, such as fertilizers and pesticides, are applied to farm fields (see Figure below ). Some of the chemicals are picked up by rainwater. Runoff then carries the chemicals to nearby rivers or lakes. Dissolved fertilizer causes too much growth of water plants and algae. This can lead to dead zones where nothing can live in lakes and at the mouths of rivers. Some of the chemicals can infiltrate into groundwater. The contaminated water comes up in water wells. If people drink the polluted water, they may get sick. Please answer this question : Who will be more likely to cause people to get sick?
A: Jimbo

Q: You are given a new situation: Hill town was full of gasoline powered vehicles, while Valley town 50 miles away, banned all gas powered vehicles and allows only electrical vehicles or horse-and-buggies. and a hint : Gasoline-powered vehicles emit a lot of harmful materials. Nitrogen oxides are formed when atmospheric nitrogen reacts with oxygen at the high temperatures found in a car engine. Carbon monoxide is a by-product of incomplete combustion of hydrocarbons. Evaporated and unused fuel releases volatile hydrocarbons into the atmosphere to help form smog. The presence of a catalytic converter in the exhaust system of the car causes these materials to react and be changed into less harmful products. Please answer this question : Which town emitted more nitrogen oxides?
A: Hill

Q: You are given a new situation: Two cousins were fascinated about food chains in nature. Liam started reading about apex predators, while Fox read about grazers and large herbivores. and a hint : An apex predator, also known as an alpha predator or top predator, is a predator at the top of a food chain, with no natural predators.Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels. Food chains are often far shorter on land, usually limited to being secondary consumers for example, wolves prey mostly upon large herbivores (primary consumers), which eat plants (primary producers). The apex predator concept is applied in wildlife management, conservation and ecotourism. Please answer this question : Which cousin learned more about predators with no natural predators?
A:
Liam
