Problem: I read this background article the other day: Air pollution can also indirectly cause other health issues and even deaths. Air pollutants can cause an increase in cancer including lung cancer, eye problems, and other conditions. For example, using certain chemicals on farms, such as the insecticide DDT (dichlorodiphenyltrichloroethane) and toxic PCBs (polychlorinated biphenyl), can cause cancer. Indoors, pollutants such as radon or asbestos can also increase your cancer risk. Lastly, air pollution can lead to heart disease, including heart attack and stroke. I am facing a new situation today: Two neighboring towns had different methods of growing crops. Lean town used insecticides, while Bean town did not. Lean town had high levels of air pollution. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which town had fewer inhabitants experiencing eye problems?

A: Bean
Problem: Given the question: I read this background article the other day: Other pathogens spread when they get on objects or surfaces. A fungus may spread in this way. For example, you can pick up the fungus that causes athlete's foot by wearing shoes that an infected person has worn. You can also pick up this fungus from the floor of a public shower or other damp areas. After acne, athlete's foot is the most common skin disease in the United States. Therefore, the chance of coming in contact with the fungus in one of these ways is fairly high. I am facing a new situation today: Two brothers worked out a few times per week at the same gym. Tim got athlete's food from the gym, but Dan didn't. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother got athlete's foot from walking barefoot in damp areas?
++++++++++++++++++++++++++++++++
The answer is:
Tim
input question: I read this background article the other day: The Figure below shows decibel levels of several different sounds. As decibel levels get higher, sound waves have greater intensity and sounds are louder. For every 10-decibel increase in the intensity of sound, loudness is 10 times greater. Therefore, a 30-decibel "quiet" room is 10 times louder than a 20-decibel whisper, and a 40-decibel light rainfall is 100 times louder than the whisper. High-decibel sounds are dangerous. They can damage the ears and cause loss of hearing. I am facing a new situation today: Jeremy works on a construction site operating a jackhammer and a large welding machine. Jeremy is frequently exposed to sounds with high decibel levels due to being around these machines so often. Jeremy's brother, Alexander, on the other hand works in a library. Unlike Jeremy, Alexander is frequently exposed to sounds with very low decibel levels during his work. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Whose ears, Jeremy's or Alexander's, are less at risk of being damaged due to the sounds they encounter frequently????
output answer: Alexander's
I read this background article the other day: Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. I am facing a new situation today: Tony and Greg are brothers. They are currently in the kitchen eating a snack together. Greg is eating a stalk of celery while Tony is eating out of a bowl of candy. Tony remarks that he doesn't know how Greg enjoys such a bland snack. Greg just gives Tony an angry glare before getting up to go into the living room. On the living room table, Greg finds a glass of milk and a bowl of milk. The glass of milk has started to get thick, but the bowl of milk appears to be still fresh. Greg rolls his eyes at the mess and walks away. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person will experience more tooth decay?
----
Answer: Tony
Q: I read this background article the other day: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid. I am facing a new situation today: China used alternative fuels to generate electricity, while Mongolia burned lots of fossil fuels. There were frequent debates between the two countries on this matter. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country released fewer anthropogenic emissions?
A: China
[Q]: I read this background article the other day: A large log placed in a fire will burn relatively slowly. If the same mass of wood were added to the fire in the form of small twigs, they would burn much more quickly. This is because the twigs provide a greater surface area than the log does. An increase in the surface area of a reactant increases the rate of a reaction. Surface area is larger when a given amount of a solid is present as smaller particles. A powdered reactant has a greater surface area than the same reactant as a solid chunk. In order to increase the surface area of a substance, it may be ground into smaller particles or dissolved into a liquid. In solution, the dissolved particles are separated from each other and will react more quickly with other reactants. I am facing a new situation today: Two groups of friends went camping , but camped separately a few hundred yards away and started a fire each. Both groups had the same volume of wood. Group P had larger logs, while group Q had small twigs, sawdust and kindlings. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group had brought smaller particles of wood to burn?
****
[A]:
group Q
