user: Please answer this: I read this background article the other day: 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.  I am facing a new situation today: Two coworkers are sitting in the large break room eating lunch and watching the news on TV when they see an advertisement for glasses. John, upon seeing the ad, comments that he really should go and get a new pair since he is nearsighted and hasn't gotten a new pair of glasses in a couple years. Rick says he is glad that he doesn't need to wear glasses because it seems like such a pain to have to always have something on your face. John nods in agreement and then both men turn to see a woman at the other side of the break room waving at them and trying to get their attention.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Is John more or less likely than Rick to correctly identify the woman?

Answer: less
Problem: I read this background article the other day: Water stratification is when water masses with different properties - salinity (halocline), oxygenation (chemocline), density (pycnocline), temperature (thermocline) - form layers that act as barriers to water mixing which could lead to anoxia or euxinia.[1] These layers are normally arranged according to density, with the least dense water masses sitting above the more dense layers.  Water stratification also creates barriers to nutrient mixing between layers. This can affect the primary production in an area by limiting photosynthetic processes. When nutrients from the benthos cannot travel up into the photic zone, phytoplankton may be limited by nutrient availability. Lower primary production also leads to lower net productivity in waters.[2]  I am facing a new situation today: High lake had a lot of fresh and salt water mixing, therefore presented layers of stratified water.The water was poor in nutrients.Low lake had no such problems and it was a very abundant and prolific fishing spot.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which lake had less phytoplankton?

A: High
Problem: Given the question: I read this background article the other day: Depleted soils can be protected from soil erosion by groundcover plants such as naturally growing grasses in agroforestry systems. These help to stabilise the soil as they increase cover compared to short-cycle cropping systems. Soil cover is a crucial factor in preventing erosion. Cleaner water through reduced nutrient and soil surface runoff can be a further advantage of agroforestry. The runoff can be reduced by decreasing its velocity and increasing infiltration into the soil. Compared to row-cropped fields nutrient uptake can be higher and reduce nutrient loss into streams.Further advantages concerning plant growth:  I am facing a new situation today: Rob is an environmental scientist. He was doing a study on agroforestry. To test the sustainability of agroforestry he conducted two pilot projects, pilot A and pilot B. In pilot A, he used a land for agrofroestry. In pilot B, he used a land for usual row-cropping. He needed to find the pros and cons of both systems.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would pilot B have less or more soil cover than pilot A?

The answer is:
less
input question: I read this background article the other day: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions – primarily from use of fossil fuels and deforestation – have rapidly increased its concentration in the atmosphere, leading to global warming.  Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid.  I am facing a new situation today: Two counties were part of the same region. Green county used alternative methods to produce energy, while Brown county used fossil fuels and released a lot of carbon dioxide into the atmosphere.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which county released more greenhouse gases in Earth's atmosphere????
output answer: Brown
I read this background article the other day: 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.  I am facing a new situation today: Bill and Paul were farmers. Bill used insecticides to get read of aphids, while his buddy farmer Paul didn't.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farmer dealt with fewer aphids resistant to carbamates?
----
Answer: Paul
Q: I read this background article the other day: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. As a result, they are more likely to bump into one another and to collide with greater force. For example, food spoils because of chemical reactions, and these reactions occur faster at higher temperatures (see the bread on the left in the Figure below ). This is why we store foods in the refrigerator or freezer (like the bread on the right in the Figure below ). The lower temperature slows the rate of spoilage.  I am facing a new situation today: Rob is a chemist with a pharmaceutical company. He is trying to devise a technique that would  be able to control chemical reactions. For that, he conducted two tests. In the first test, he used warmer reactants. He called it reactant A. In the second test, he used cooler reactants. He called it reactant B.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would particles move faster or slower in reactant A than in reactant B?
A:

assistant: faster
