Question: I read this background article the other day: Many different chemical substances cause cancer. Dozens of chemicals in tobacco smoke, including nicotine, have been shown to cause cancer ( Figure below ). In fact, tobacco smoke is one of the main sources of chemical carcinogens. Smoking tobacco increases the risk of cancer of the lung, mouth, throat, and bladder. Using smokeless tobacco can also cause cancer. Other chemicals that cause cancer include asbestos, formaldehyde, benzene, cadmium, and nickel. I am facing a new situation today: Two friends met after 20 years. Tom had been smoking tobacco all these years and had some health problems related to that, while Randy quit smoking 25 years ago. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend had a lower risk of developing cancer of the throat?
Answer: Randy
[Q]: I read this background article the other day: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis. I am facing a new situation today: Ronaldo and Jeff are two college roommates that have similar body structure and similar physical activity levels. Ronaldo is a nutrition enthusiast and eats a diet with appropriately low amounts of fat and cholesterol. Jeff, on the other hand, doesn't really care about nutrition at all. He eats whatever he wants, whenever he wants, and as a result he consumes a diet with an inappropriately high amount of fat and cholesterol. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who is less likely to have increased blood lipid levels?
****
[A]: Ronaldo
input: Please answer the following: I read this background article the other day: Allergy symptoms can range from mild to severe. Mild symptoms might include itchy eyes, sneezing, and a runny nose. Severe symptoms can cause difficulty breathing, which may be life threatening. Keep in mind that it is the immune system and not the allergen that causes the allergy symptoms. Allergy symptoms can be treated with medications such as antihistamines. Severe allergic reactions may require an injection of the hormone epinephrine. These treatments lessen or counter the immune system's response. I am facing a new situation today: Two groups of students went on a field trip. Group Scouts visited a bee farm, while group Bears went to a salmon hatchery. Group Scouts had children experiencing mild allergic reactions, while one student had severe allergic reactions to a bee sting. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group had more students experiencing difficulty breathing?
++++++++++
output: Scouts
Please answer this: I read this background article the other day: On Earth, the common weather phenomena include wind, cloud, rain, snow, fog and dust storms. Less common events include natural disasters such as tornadoes, hurricanes, typhoons and ice storms. Almost all familiar weather phenomena occur in the troposphere (the lower part of the atmosphere). Weather does occur in the stratosphere and can affect weather lower down in the troposphere, but the exact mechanisms are poorly understood.Weather occurs primarily due to air pressure, temperature and moisture differences between one place to another. These differences can occur due to the sun angle at any particular spot, which varies by latitude from the tropics. In other words, the farther from the tropics one lies, the lower the sun angle is, which causes those locations to be cooler due the spread of the sunlight over a greater surface. The strong temperature contrast between polar and tropical air gives rise to the large scale atmospheric circulation cells and the jet stream. Weather systems in the mid-latitudes, such as extratropical cyclones, are caused by instabilities of the jet stream flow (see baroclinity). Weather systems in the tropics, such as monsoons or organized thunderstorm systems, are caused by different processes. I am facing a new situation today: Two continents were separated by a large ocean. Oceania had milder weather and experienced common weather phenomena, while Lemuria experienced natural disasters. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which continent experienced wind phenomena?
++++++++
Answer: Oceania
Problem: I read this background article the other day: The water level is seasonal, being lowered by about 10 feet (3.0 m) over the winter. The reservoir fills in the spring from snow melt and underground springs. The lake is usually at full level by late spring, but in the occasional years of low snow melt and low rainfall, it may remain up to several feet below its typical level. Water is let out of the lake in the fall so that ice will not damage docks and other structures around the lake. This also leads to excellent water quality, as a significant portion of the water is replaced every year. I am facing a new situation today: The water level in Large Lake was high in March, 3 feet higher in April, and 7 feet higher still in May. It dropped to a much lower level in September, October and November, when they released a significant portion of the water as a yearly chore. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: When was the water level lower, in April or in March?

A: in March
input: Please answer the following: I read this background article the other day: Light may transfer its energy to matter rather than being reflected or transmitted by matter. This is called absorption . When light is absorbed, the added energy increases the temperature of matter. If you get into a car that has been sitting in the sun all day, the seats and other parts of the car's interior may be almost too hot to touch, especially if they are black or very dark in color. That's because dark colors absorb most of the sunlight that strikes them. I am facing a new situation today: There are two cats sitting outside in the sun. One of them has white fur and one of them has black fur. Tina sees them and goes to pet them both. Robert is planning a beach trip and needs to buy a new lounge chair to sit in because his old one is broken. At the store he sees two chairs that he likes. One of the chairs is dark blue and one of the chairs is light blue. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: If Robert wants his chair to stay cooler during the day which color should he buy?
++++++++++
output:
light blue
