Question: Drought is major concern in the Midwest. To confront the problem scientists are trying to develop drought-resistant crops. To that end, they took a plant that was not exposed to drought. They labeled it as plant A. Then they took a similar plant, and repeatedly exposed it to drought. They labeled it as plant B. They wanted to find out what makes a plant drought-resistant. Given the paragraph above, please answer correctly the following question: In which plant there would be more water loss, plant A or plant B? Hint: One interesting thing that has been found in plants that are consistently exposed to drought, is their ability to form a sort of "memory". In a study by Tombesi et al., they found plants who had previously been exposed to drought were able to come up with a sort of strategy to minimize water loss and decrease water use. They found that plants who were exposed to drought conditions actually changed they way the regulated their stomates and what they called "hydraulic safety margin" so as to decrease the venerability of the plant. By changing the regulation of stomata and subsequently the transpiration, plants were able to function better in situations where the availability of water decreased.
Answer: plant A

Question: Blue island and Red island were two big sister islands situated 100 miles from each other. People on Blue island used gas powered vehicles, while people on Red island used electrical vehicles. The people on Blue island presented more respiratory problems. Given the paragraph above, please answer correctly the following question: Which island had more volatile hydrocarbons into the atmosphere? Hint: Gasoline-powered vehicles emit a lot of harmful materials. Nitrogen oxides are formed when atmospheric nitrogen reacts with oxygen at the high temperatures found in a car engine. Carbon monoxide is a by-product of incomplete combustion of hydrocarbons. Evaporated and unused fuel releases volatile hydrocarbons into the atmosphere to help form smog. The presence of a catalytic converter in the exhaust system of the car causes these materials to react and be changed into less harmful products.
Answer: Blue

Question: Two counties paid a study about acid rain. They found out Hill county had experienced that, while New county hadn't. Given the paragraph above, please answer correctly the following question: Which county experienced more air pollution? Hint: 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.
Answer:
Hill
