input: Please answer the following: I have a new situation: Hydrologists studied two samples of rain water. Jim studied an acid rain sample from a nearby city, and Dan studied a sample of water from another town. But I can use this 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. What is an answer for this question: Which hydrologist learned more about air pollution?

Please answer this: I have a new situation: 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. But I can use this background: 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. What is an answer for this question: Which person will experience more tooth decay?

Answer: Tony
Problem: I have a new situation: John wanted to see how he would fare in high altitude compared to ground-level. So, he first measured his responses in ground-level. He labeled this part of the study as case A. Then he board on an airplane to reach high altitude, and measured his responses there. He labeled this part of the study as case B. Now, John knows how he needs to prepare for a high altitude hiking. But I can use this background: As shown here, pressure decreases to less than 25% of ground-level atmospheric pressure when we get to an altitude of about six miles. Since this is a common cruising altitude for commercial airplanes, pressurized cabins are needed for the comfort and survival of the passengers. This is because the density of the air decreases along with the decreasing air pressure, so there is less oxygen in a breath of air. You've probably noticed this effect in high-mountain areas, as it often feels harder to breath. What is an answer for this question: Which case would see lower air density, case A or case B?

A: case B
Problem: Given the question: I have a new situation: Dan is a dance instructor. In an upcoming dance competition he has to send two groups of students, group A and group B. He dressed group A students with godet. But he didn't dress group B students with godet. There are two categories of dance, category C and category D, in the dance competition. Category C requires lots of motion, but category D does not required much motion. Dan has to decide which of his student groups would compete in category C and which group to compete in category D. But I can use this background: A godet (/ode/ or /odt/)[1] is an extra piece of fabric in the shape of a circular sector which is set into a garment, usually a dress or skirt.[2] The addition of a godet causes the article of clothing in question to flare, thus adding width and volume.[3] Adding a godet to a piece of clothing also gives the wearer a wider range of motion.[4] What is an answer for this question: Which group should Dan select for category C competition, group A or group B?

The answer is:
group A
input question: I have a new situation: Two neighboring towns, Pine town and Willow town, used different types of woods for lumber et al. Willow town used hardwoods, while Pine town used softwoods. But I can use this background: Conifers have many uses. They are important sources of lumber and are also used to make paper. Resins, the sticky substance you might see oozing out of a wound on a pine tree, are collected from conifers to make a variety of products, such as the solvent turpentine and the rosin used by musicians and baseball players. The sticky rosin improves the pitcher's hold on the ball or increases the friction between the bow and the strings to help create music from a violin or other stringed instrument. What is an answer for this question: Which town used more conifers to make paper????
output answer: Pine
input question: I have a new situation: Two brothers liked natural sciences. Ben decided to study Ecology, while his brother Dan decided to study Geography. They studied a lot and became very good at these subjects. But I can use this background: Ecology is the study of ecosystems. An ecosystem consists of all the living and nonliving components of the habitat. Whereas nutrients and certain elements are recycled through ecosystems, energy moves in just one direction. Many interactions among species within an ecosystem are centered around the flow of energy. The formation of ecosystems, from new land to current habitats, is usually based on the pioneer species, and these species are able to live in an area due to the nonliving factors, such as the climate, the soil and the amount of rainfall, of that area. The populations within an ecosystem also determine the stability of the system. Recent tremendous increases in the human population have raised many important ecological issues. What is an answer for this question: Which brother studied fewer nonliving components of the habitat????
output answer:
Dan
