Problem: I read this background article the other day: Ski cross is a type of skiing competition. Despite its being a timed racing event, it is often considered part of freestyle skiing because it incorporates terrain features traditionally found in freestyle. Ski cross courses have both naturally occurring terrain and artificial features including big-air jumps and high-banked turns. What sets ski cross apart from other alpine skiing disciplines is that there's more than one skier racing down the course.[1] Any intentional contact with other competitors leads to disqualification. I am facing a new situation today: Greg is an avid skier. He competes in many skiing competitions. He won several medals in those competitions. This November he will compete in two competitions - competition A, which is ski cross and competition B, which is an alpine skiing competition. Greg's fellow skier Bob is also competing in the same competitions. They both are exited about it. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: In which competition they will not see multiple skiers racing down the course, competition A or competition B?

A: competition B
Problem: Given the question: I read this background article the other day: In addition to insects, weeds have also been a menace to farmers - just ask anyone with a garden how much they hate weeds. They can quickly compete for water and nutrients needed by other plants. Sure, farmers can use herbicides to kill weeds, but do these chemicals also harm the crops? Can biotechnology help with this issue? Some crops have also been genetically engineered to acquire tolerance to the herbicides - allowing the crops to grow, but killing the weeds. But the lack of cost effective herbicides with a broad range of activity - that do not harm crops - is a problem in weed management. Multiple applications of numerous herbicides are routinely needed to control the wide range of weeds that are harmful to crops. And at times these herbicides are being used as a preventive measure that is, spraying to prevent weeds from developing rather than spraying after weeds form. So these chemicals are being added to crops. This practice is followed by mechanical and/or hand weeding to control weeds that are not controlled by the chemicals. Crops that are tolerant of herbicides would obviously be a tremendous benefit to farmers ( Figure above ). The introduction of herbicide tolerant crops has the potential to reduce the number of chemicals needed during a growing season, thereby increasing crop yield due to improved weed management and decreased harm to the crops. I am facing a new situation today: Because of the weed and insect menace villagers from North village decided to use herbicide tolerant crops. South village decided to postpone a decision and kept using regular seeds. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which village added crops that are a tremendous benefit to farmers?

The answer is:
North
input question: 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 scientists examined two fires. Group A put a large log on it, and group B made a fire with small twigs. They wanted to see which fire would last longer. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group had a fire with wood made from smaller particles????
output answer: group B
I read this background article the other day: Sand mining is a direct cause of erosion, and impacts the local wildlife.[2] Various animals depend on sandy beaches for nesting clutches, and mining has led to the near extinction of gharials (a species of crocodile) in India. Disturbance of underwater and coastal sand causes turbidity in the water, which is harmful for organisms like coral that need sunlight. It can also destroy fisheries, financially harming their operators. Removal of physical coastal barriers, such as dunes, sometimes leads to flooding of beachside communities, and the destruction of picturesque beaches causes tourism to dissipate. Sand mining is regulated by law in many places, but is often done illegally.[3] Globally, it is a $70 billion industry, with sand selling at up to $90 per cubic yard.[4] I am facing a new situation today: Nigeria invested in sand mining and started mining coastal barriers. Congo continued preserving their picturesque beaches. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country destroyed fewer coral riffs?
----
Answer: Congo
Q: I read this background article the other day: Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. I am facing a new situation today: The Malegese Ocean is primarily connected to one river. This river is next to Hilda's farm that she has lived on for decades. Ever since she was a child, she was taught that it's important to dump excess fertilizer into the river. So, that's what she does whenever she has leftover fertilizer she isn't going to use. The Dundrin Ocean is connected to many rivers. However, these rivers are located primarily in uninhabited and natural areas of the world. There is one farm near the Dundrin, though, which is owned by Luke. Luke never disposes of any of his garbage in the ocean or rivers near his farm, and he chooses instead to store excess fertilizer for the future or properly dispose of his trash. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which ocean would it be easier to catch a fish in?
A: The Dundrin
[Q]: I read this background article the other day: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. I am facing a new situation today: Two friends studied permaculture together. Bill studied about mycorrhiza, while Red studied about hugel kultur. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend learned more about surface areas of root systems?
****
