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 groups of runners attended a 5k event downtown. Brown group warmed up properly before the race, but Red group did no such thing and suffered the consequences. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group didn't do a slow increase in the intensity of a physical activity?

Answer: Red
Q: I read this background article the other day: Plants can grow as much as 50 percent faster in concentrations of 1,000 ppm CO2 when compared with ambient conditions, though this assumes no change in climate and no limitation on other nutrients. Elevated CO2 levels cause increased growth reflected in the harvestable yield of crops, with wheat, rice and soybean all showing increases in yield of 1214% under elevated CO2 in FACE experiments.Increased atmospheric CO2 concentrations result in fewer stomata developing on plants which leads to reduced water usage and increased water-use efficiency. Studies using FACE have shown that CO2 enrichment leads to decreased concentrations of micronutrients in crop plants. This may have knock-on effects on other parts of ecosystems as herbivores will need to eat more food to gain the same amount of protein.The concentration of secondary metabolites such as phenylpropanoids and flavonoids I am facing a new situation today: Jerry and Gary each live in separate cities, but both run equally sized farms that grow the same produce. The cities they live in have very similar environments with the only difference being that the CO2 levels in Jerry's town are elevated, and in Gary's they are not. Jerry and Gary regularly talk on the phone and compare notes with each other since their farms are so similar. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who will have less of their crops eaten by animals?
A: Gary
Question: 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 mycologists were studying fungi. Jim studied more about wood eating mushrooms and gourmet mushrooms, while George decided to study more about mycorrhiza, and its benefits for humans. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which mycologist learned less about how fungi increase the surface area of the plant's root system?
Answer: Jim
[Q]: I read this background article the other day: Biodiversity is determined by many things, and one of them is abiotic stress. If an environment is highly stressful, biodiversity tends to be low. If abiotic stress does not have a strong presence in an area, the biodiversity will be much higher.This idea leads into the understanding of how abiotic stress and endangered species are related. It has been observed through a variety of environments that as the level of abiotic stress increases, the number of species decreases. This means that species are more likely to become population threatened, endangered, and even extinct, when and where abiotic stress is especially harsh. I am facing a new situation today: Italy had two distinct regions. Northern region where the animals are exposed to a lot of abiotic stress, and the southern region, where the animals experience almost no abiotic stress. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which region had more species with populations threatened?
****
[A]: Northern
input: Please answer the following: I read this background article the other day: Because of its temperature, the atmosphere emits infrared radiation. For example, on clear nights Earth's surface cools down faster than on cloudy nights. This is because clouds (H2O) are strong absorbers and emitters of infrared radiation. This is also why it becomes colder at night at higher elevations. I am facing a new situation today: David was visiting Europe last summer. First he visited London. To his dismay, it was overcast all night. Then he flew to Rome. There the sky was as clear as you could get at night. David was very happy about it. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would Earth's surface cool down faster or slower in Rome than in London?
++++++++++
output: faster
I read this background article the other day: Hepatitis viruses can develop into a chronic viral infection that leads to liver cancer. Infection by human T-lymphotropic virus can lead to tropical spastic paraparesis and adult T-cell leukaemia. Human papillomaviruses are an established cause of cancers of cervix, skin, anus, and penis. Within the Herpesviridae, Kaposi's sarcoma-associated herpesvirus causes Kaposi's sarcoma and body-cavity lymphoma, and EpsteinBarr virus causes Burkitt's lymphoma, Hodgkin's lymphoma, B lymphoproliferative disorder, and nasopharyngeal carcinoma. Merkel cell polyomavirus closely related to SV40 and mouse polyomaviruses that have been used as animal models for cancer viruses for over 50 years. I am facing a new situation today: Two medical students had to study about viruses that cause cancers in humans. Brady studied about hepatitis viruses, while Dean studied about human papillomaviruses and Herpesviridae. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student read more about liver cancer?

Brady
