[Q]: I read this background article the other day: Electrons can be removed from some objects using friction, simply by rubbing one substance against another substance. There are many examples of objects becoming charged by friction, including a rubber comb through hair, and a balloon on a sweater. In both these instances, the electrons move from the second object to the first, causing the first object to become negatively charged and the second one positively charged. Friction between the tires on a moving car and the road cause the tires to become charged, and wind causes friction between clouds and air which causes clouds to become charged and can result in tremendous bolts of lightning. I am facing a new situation today: Weather patterns in two cities are rather different. Much to the dismay of many residents of the town, the weather in Smallville is often windy and cloudy. Citizens of Klangton are much happier since they rarely experience heavy winds and generally only have a couple clouds in the sky. Their weather is almost always sunny with almost clear skies. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Do the clouds in Klangton have more or less electrons than the clouds in Smallville?

[A]: less
input: Please answer the following: I read this background article the other day: Rain dissolves fertilizer in the soil. Runoff carries it away. The fertilizer ends up in bodies of water, from ponds to oceans. Nitrogen is a fertilizer in the water. Since there is a lot of nitrogen, it causes algae to grow out of control. Pictured below is a pond covered with algae ( Figure below ). Algae use up carbon dioxide in the water. After the algae die, decomposers break down the dead tissue. The decomposers use up all the oxygen in the water. This creates a dead zone. A dead zone is an area in a body of water where nothing grows because there is too little oxygen. There is a large dead zone in the Gulf of Mexico ( Figure below ). The U.S. states outlined on the map have rivers that drain into the Gulf of Mexico. The rivers drain vast agricultural lands. The water carries fertilizer from these areas into the Gulf. I am facing a new situation today: Two neighboring towns from Texas produced their food in different ways. Silver town was sustainable and didn't use any fertilizers or pesticides, while Gold town did. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which town didn't play a part in causing a large dead zone in the Gulf of Mexico ?

output: Silver
Please answer this: I read this background article the other day: A few insects, such as mayflies and some moths, never eat. That's because their lives are over in just a few hours or days. Once these insects become adults, they lay eggs, and then die. On the other hand, some insects are very healthy eaters. A silkworm eats enough leaves to increase its weight more than 4,000 times in just 56 days, as the silkworm increases in size about 10,000 times since birth. A locust eats its own weight in plants every day. Just imagine eating your own weight in food every day. You probably couldn't. You would most likely get very sick even if you tried. I am facing a new situation today: Two agricultural students had to prepare for exams. Jane had the entomology exam, so she studied about insects. Nora had the chemistry exam, so she studied about alkanes. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student learned less about insects that never eat?
++++++++
Answer: Nora
Problem: I read this background article the other day: 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. I am facing a new situation today: Berg city used only gas powered vehicles while Hill city used electrical vehicles. The two cities had a similar population and vehicle numbers. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which city experienced more smog?

A: Berg
Problem: Given the question: I read this background article the other day: Einstein showed in his thought experiments that people travelling at different speeds, while agreeing on cause and effect, measure different time separations between events, and can even observe different chronological orderings between non-causally related events. Though these effects are typically minute in the human experience, the effect becomes much more pronounced for objects moving at speeds approaching the speed of light. Subatomic particles exist for a well known average fraction of a second in a lab relatively at rest, but when travelling close to the speed of light they are measured to travel farther and exist for much longer than when at rest. According to the special theory of relativity, in the high-speed particle's frame of reference, it exists, on the average, for a standard amount of time known as its mean lifetime, and the distance it travels in that time is zero, because its velocity is zero. Relative to a frame of reference at rest, time seems to "slow down" for the particle. Relative to the high-speed particle, distances seem to shorten. Einstein showed how both temporal and spatial dimensions can be altered (or "warped") by high-speed motion. I am facing a new situation today: David wanted to test the theory of Einstein. To that end, he measured the time perceived by an airline pilot, who naturally traveled very fast. He labeled it as case A. To compare the pilot with a slower traveler he measured the time perceived by a semi truck driver covering the same distance. He labeled it as case B. He was amazed by the counter intuitive results he got from the experiment. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: According to Einstein, who would seem to gain less time, case A or case B?
++++++++++++++++++++++++++++++++
The answer is:
case B
Problem: I read this background article the other day: Precipitation in grasslands is equal to or less than evapotranspiration and causes soil development to operate in relative drought. Leaching and migration of weathering products is therefore decreased. Large amounts of evaporation causes buildup of calcium (Ca) and other large cations flocculate clay minerals and fulvic acids in the upper soil profile. Impermeable clay limits downward percolation of water and fulvic acids, reducing chemical weathering and podzolization. The depth to the maximum concentration of clay increases in areas of increased precipitation and leaching. When leaching is decreased, the Ca precipitates as calcite (CaCO3) in the lower soil levels, a layer known as caliche. I am facing a new situation today: Monsoon plays a big role in shaping local climates. In some places of the Horn of Africa monsoon causes heavy rainfall. But across the Red Sea the Arabian Peninsula mostly misses the monsoon. As a result, they have minimal rainfall throughout the year. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would less or more calcite precipitate in the lower soil levels in Horn of Africa than in Arabian Peninsula?

A:
less
