Question: 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: Two farmers had different pests attacking their plants. John had a big aphid problem, so he used all the methods available to get rid of them. Mike had a slug problem, but had almost no aphides. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farmer didn't learn that spraying plants thoroughly with a strong water jet every few days may be sufficient protection from aphids?
Answer: Mike
[Q]: I read this background article the other day: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ). I am facing a new situation today: Two teams were competing in a 5 km race. White team warmed up before the race, but Blue team arrived with a bus late and didn't have time to warm up properly before the race. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which team experienced more muscle and tendon injuries?
****
[A]: Blue
input: Please answer the following: I read this background article the other day: Sugaring is a food preservation method similar to pickling. Sugaring is the process of desiccating a food by first dehydrating it, then packing it with pure sugar. This sugar can be crystalline in the form of table or raw sugar, or it can be a high sugar density liquid such as honey, syrup or molasses. The purpose of sugaring is to create an environment hostile to microbial life and prevent food spoilage. Sugaring is commonly used to preserve fruits as well as vegetables such as ginger. From time to time sugaring has also been used for non-food preservations. For example, honey was used as part of the mummification process in some ancient Egyptian rites. A risk in sugaring is that sugar itself attracts moisture. Once a sufficient moisture level is reached, native yeast in the environment will come out of dormancy and begin to ferment the sugars into alcohol and carbon dioxide. This leads to the process of fermentation. Although fermentation can be used as a food preservation method, it must be intentionally controlled, or the results will tend to be unpleasant. I am facing a new situation today: Ann decided to candy half of the fruit he received as a gift. She kept the other half to eat fresh and do juicing. She candied ginger, plums pears, and she didn't candy apples, oranges apricots and bananas. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which fruit contains more crystallized sugar, plums or oranges?
++++++++++
output: plums
Please answer this: I read this background article the other day: The epidermis also contains melanocytes , which are cells that produce melanin. Melanin is the brownish pigment that gives skin much of its color. Everyone has about the same number of melanocytes, but the melanocytes of people with darker skin produce more melanin. The amount of melanin produced is determined by heredity and exposure to UV light, which increases melanin output. Exposure to UV light also stimulates the skin to produce vitamin D . Because melanin blocks UV light from penetrating the skin, people with darker skin may be at greater risk of vitamin D deficiency. I am facing a new situation today: Matt and his brother Jesse are twins. They look almost identical. If it weren't for the fact that Jesse has a slightly darker skin complexion you wouldn't be able to tell them apart. In fact one year Matt was out in the sun for a long time and picked up a bit of a tan so they actually did look exactly alike. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will the risk of a vitamin D deficiency increase or decrease when you skin is darker?
++++++++
Answer: increase
Problem: I read this background article the other day: The body's second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. This increases blood flow to the damaged area, which makes the area red and slightly warm. The chemicals also attract white blood cells called neutrophils to the wound and cause them to leak out of blood vessels into the damaged tissue. I am facing a new situation today: Two medical school students named Dan and Bob learned about the human immune system. Dan studied more about the subject, and became very interested to pursue it more in the future. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student didn't learn that the infected skin area may become warm?

A: Bob
input: Please answer the following: I read this background article the other day: Earthquakes may take place every day near a volcano. But before an eruption, the number and size of earthquakes increases. This is the result of magma pushing upward into the magma chamber. This motion causes stresses on neighboring rock to build up. Eventually the ground shakes. A continuous string of earthquakes may indicate that a volcano is about to erupt. Scientists use seismographs to record the length and strength of each earthquake. I am facing a new situation today: Two sister villages, both situated near volcanoes, experience daily earthquakes. Green village started recording an increased size and number of earthquakes one day. Blue village didn't experience a change in the number of earthquakes. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which village started experiencing more ground shaking?

Green
