Please answer this: I read this background article the other day: As shown here, pressure decreases to less than 25% of ground-level atmospheric pressure when we get to an altitude of about six miles. Since this is a common cruising altitude for commercial airplanes, pressurized cabins are needed for the comfort and survival of the passengers. This is because the density of the air decreases along with the decreasing air pressure, so there is less oxygen in a breath of air. You've probably noticed this effect in high-mountain areas, as it often feels harder to breath. I am facing a new situation today: Pam and Angela live in different cities and are talking to each other on the phone while they are sitting outside. Pam lives in Dunder, a city located at sea level, and Angela lives in Mifflin, a city up high in the mountains. Although they don't get to see each other much any more due to the distance between them, they make sure to stay in regular contact. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which woman gets less oxygen per single breath?

Answer: Angela

Please answer this: I read this background article the other day: Making these healthy lifestyle choices can also help prevent some types of cancer. In addition, you can lower the risk of cancer by avoiding carcinogens , which are substances that cause cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen. How to choose a sunscreen that offers the most protection is explained below ( Figure below ). Some people think that tanning beds are a safe way to get a tan. This is a myth. Tanning beds expose the skin to UV radiation. Any exposure to UV radiation increases the risk of skin cancer. It doesn't matter whether the radiation comes from tanning lamps or the sun. I am facing a new situation today: Paul started a healthy lifestyle because he wanted to avoid getting cancer. His cousin Pete laughed at him, and continued eating fast-foods, smoking and disregarding his health completely. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which cousin didn't start avoiding carcinogens?
++++++++
Answer: Pete

Please answer this: I read this background article the other day: Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes. I am facing a new situation today: Burr township is situated on the western side of the ridge, at a lower altitude, and is experiencing atmospheric convection every once in a while, while Jolt township, on the eastern side, has a less windy, less cloudy environment and is situated at a higher altitude. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which township is experiencing more clouds?
++++++++
Answer:
Burr
