user: 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: Beth and Sally are both on the high school basketball team and are about to play a match against their rival school. This match is extremely important, and students from both schools always turn out in droves to support their team. Last year, Beth and Sally's team lost so they are extra motivated this year to win. Before the game, Beth spends her time running in place and doing jumping jacks to prepare, and Sally spends her time talking to her friends who are sitting in the bleachers cheering the team on.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who is more likely to be injured during the game?
----
Answer: Sally


I read this background article the other day: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth’s surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465°C (860°F). That’s hot enough to melt lead!  I am facing a new situation today: Two groups of children studied about some of the planets from our Solar system and their atmospheres. Group E studied about Earth, while group V studied about the planet Venus.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group studied less about temperatures at the surface of Venus?

Answer: Group E


I read this background article the other day: Air pollution can also indirectly cause other health issues and even deaths. Air pollutants can cause an increase in cancer including lung cancer, eye problems, and other conditions. For example, using certain chemicals on farms, such as the insecticide DDT (dichlorodiphenyltrichloroethane) and toxic PCBs (polychlorinated biphenyl), can cause cancer. Indoors, pollutants such as radon or asbestos can also increase your cancer risk. Lastly, air pollution can lead to heart disease, including heart attack and stroke.  I am facing a new situation today: Two neighboring towns had different methods of growing crops. Lean town used insecticides, while Bean town did not. Lean town had high levels of air pollution.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which town had fewer inhabitants experiencing eye problems?
