Please answer this: 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 of athletes were attending a competition. Brown team arrived in time and started their warm up, but Green team arrived late and skipped their warm up so they experienced some people getting injured. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which team experienced an increased heart rate?
++++++++
Answer: Brown

Please answer this: I read this background article the other day: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe. I am facing a new situation today: Two cousins went for a blood test. Tim found out he had hemophilia, while John was normal. Tim had to start taking medication. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which cousin has a smaller chance of bleeding to death?
++++++++
Answer: John

Please answer this: 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: Who is causing less marine pollution?
++++++++
Answer:
Luke
