Q: I read this background article the other day: Millions of people in the world jog for exercise. For the most part, jogging can be a healthy way to stay fit. However, problems can also develop for those who jog in the heat. Excessive sweating can lead to electrolyte loss that could be life-threatening. Early symptoms of electrolyte deficiency can include nausea, fatugue, and dizziness. If not treated, individuals can experience muscle weakness and increased heart rate (which could lead to a heart attack). Many sports drinks can be consumed to restore electrolytes quickly in the body. I am facing a new situation today: Ted and Randy liked jogging. Last week while jogging by himself, Randy experienced an unpleasant episode and was taken to the hospital, because he passed out while jogging in the heat, without any water or supplements on him. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which jogger experienced less nausea?
A: Ted
Question: I read this background article the other day: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species. I am facing a new situation today: Two students from the same class, studies different types of animals. Bill studied predators, while John studied grazers. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student didn't find out that predators can be keystone species?
Answer: John
[Q]: I read this background article the other day: You don't have to suffer through an infection to gain immunity to some diseases. Immunity can also come about by vaccination. Vaccination is the process of exposing a person to pathogens on purpose so the person will develop immunity to them. In vaccination, the pathogens are usually injected under the skin. Only part of the pathogens are injected, or else weakened or dead pathogens are used. This causes an immune response without causing the disease. Diseases you are likely to have been vaccinated against include measles, mumps, and chicken pox. I am facing a new situation today: In Colorado, everyone makes sure they get vaccinated for measles. However in Ontario they don't like to get vaccines so most of the population skips them. One year a major measles outbreak occurs. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Given the people of Ontario are now required to get vaccinated for measles, will the infection rate in Ontario increase or decrease?
****
[A]: decrease
input: Please answer the following: I read this background article the other day: An allergy is a disease in which the immune system makes an inflammatory response to a harmless antigen . Any antigen that causes an allergy is called an allergen. Allergens may be inhaled or ingested, or they may come into contact with the skin. Two common causes of allergies are shown in Figure below . Inhaling ragweed pollen may cause coughing and sneezing. Skin contact with oils in poison ivy may cause an itchy rash. Other common causes of allergies include dust mites, mold, animal dander, insect stings, latex, and certain food and medications. Symptoms of a common allergy such as pollen can include sneezing, a runny nose, nasal congestion and itchy, watery eyes. I am facing a new situation today: Ben studied allergies ever since he experienced an allergic reaction to pollen. His brother Frank had no interest in the subject whatsoever, he was more interested in engineering. 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 allergies caused by animal dander?
++++++++++
output: Frank
Please answer this: I read this background article the other day: Blood vessels help regulate body processes by either constricting (becoming narrower) or dilating (becoming wider). These actions occur in response to signals from the autonomic nervous system or the endocrine system. Constriction occurs when the muscular walls of blood vessels contract. This reduces the amount of blood that can flow through the vessels (see Figure below ). Dilation occurs when the walls relax. This increases blood flows through the vessels. I am facing a new situation today: Greg is a physician working for the city hospital. Today he is seeing two patients, patient A and patient B. He noticed that patient A's blood vessels are constricted, but blood vessels of patient B are dilated. He needs to prescribe medicine according to his observation. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would patient B's blood vessels be narrower or wider than patient A's?
++++++++
Answer: wider
Question: I read this background article the other day: 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. I am facing a new situation today: Two brothers got sick and weren't feeling well. Strangely enough they found out they were infected with viruses. Tom was infected with human papillomavirus, while Chris was infected with hepatitis. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother was more at risk of developing penis cancer?
Answer:
Tom
