Problem: Given the background: One result of air pollution is acid rain. Acid rain is precipitation with a low (acidic) pH. This rain can be very destructive to wildlife. When acid rain falls in forests, freshwater habitats, or soils, it can kill insects and aquatic life. It causes this damage because of its very low pH. Sulfur oxides and nitrogen oxides in the air both cause acid rain to form ( Figure below ). Sulfur oxides are chemicals that are released from coal-fired power plants. Nitrogen oxides are released from motor vehicle exhaust. and the situation: Two counties paid a study about acid rain. They found out Hill county had experienced that, while New county hadn't. Answer the following question: Which county experienced less air pollution?

A: New

Problem: Given the question: Given the background: Hepatitis B is a contagious virus that affects the liver, infection can last from a few weeks to a serious lifelong illness. Two different types of infection exist for this disease, "acute" and "chronic." Acute Hepatitis B is a short term illness that occurs within 6 months of exposure, Chronic Hepatitis B is long term and happens when the virus remains in the body. The younger the child is, the greater their chance of developing a chronic infection and this risk goes down as the child gets older. Approximately 90% of infected infants will develop a chronic infection.[3] and the situation: Bob has just graduated from medical school. He went on to serve his community. Especially he is interested in treating children. One day he saw two children, child M and child N, and found child M is infected with Acute Hepatitis B while child N is infected with Chronic Hepatitis B. Next day he saw two other children, child O and child P. Child O was younger, but child P was older. Answer the following question: Which child had less chance of developing a chronic infection, child O or child P?
++++++++++++++++++++++++++++++++
The answer is:
child P

input question: Given the background: Generally, nearsightedness first occurs in school-age children. There is some evidence that myopia is inherited. If one or both of your parents need glasses, there is an increased chance that you will too. Individuals who spend a lot of time reading, working or playing at a computer, or doing other close visual work may also be more likely to develop nearsightedness. Because the eye continues to grow during childhood, myopia typically progresses until about age 20. However, nearsightedness may also develop in adults due to visual stress or health conditions such as diabetes. A common sign of nearsightedness is difficulty seeing distant objects like a movie screen or the TV, or the whiteboard or chalkboard in school. and the situation: Two groups of people when to the doctor. Group A had myopia, while group B had nearsightedness. Both groups got eyeglasses for their conditions. Answer the following question: Which group had their people inherit their condition????
output answer: Group A

Given the background: Human beings invented agriculture about 10,000 years ago. This provided a bigger, more dependable food supply. It also allowed people to settle down in villages and cities for the first time. Birth rates went up because there was more food and settled life had other advantages. Death rates also rose because of crowded living conditions and diseases that spread from domestic animals. Because the higher birth rates were matched by higher death rates, the human population continued to grow very slowly. and the situation: A team of archaeologists studied two human settlements, village Alpha from about 11000 years ago and village Beta, which existed 9000 years ago. Village Beta was bigger, because their inhabitants already knew about and practiced agriculture. Answer the following question: Which village had a smaller food supply?
----
Answer: Alpha

Q: Given the background: Insecticide control of aphids is difficult, as they breed rapidly, so even small areas missed may enable the population to recover promptly. Aphids may occupy the undersides of leaves where spray misses them, while systemic insecticides do not move satisfactorily into flower petals. Finally, some aphid species are resistant to common insecticide classes including carbamates, organophosphates, and pyrethroids.For small backyard infestations, spraying plants thoroughly with a strong water jet every few days may be sufficient protection. An insecticidal soap solution can be an effective household remedy to control aphids, but it only kills aphids on contact and has no residual effect. Soap spray may damage plants, especially at higher concentrations or at temperatures above 32 C (90 F); some plant species are sensitive to soap sprays. and the situation: Pam and Mary were two gardener friends. They both had some aphid infestations, but Mary had more aphids on her farm, so she used every method and insecticide available to get rid of them, with limited success. Answer the following question: Which farmer didn't spray plants thoroughly with a insecticidal soap solution?
A: Pam

[Q]: Given the background: A firm with high fixed costs requires a large number of customers in order to have a meaningful return on investment. This is where economies of scale become important. Since each firm has large initial costs, as the firm gains market share and increases its output the fixed cost (what they initially invested) is divided among a larger number of customers. Therefore, in industries with large initial investment requirements, average total cost declines as output increases over a much larger range of output levels. and the situation: City D's mayor wants to invite more businesses in the city. Three firms, firm A, firm B, and firm C, took advantage of this opportunity. Firm A does not require large initial costs, but firm B and firm C require large initial costs. Firm B managed to increase its market share, but firm C failed to increase its market share. Answer the following question: Which frim's average total cost would decline, firm B or firm C?
****
[A]:
firm B
