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: Two friends had different lifestyles. Tom adopted a healthy lifestyle choice to prevent cancer, but Bill didn't. Bill was diagnosed with cancer a year later. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which of the two friends avoided carcinogens?

Answer: Tom
Q: I read this background article the other day: Temperature is a measure of the average kinetic energy of the particles in matter. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was an increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased. Many unstable materials (such as enzymes) will be viable longer at lower temperatures. I am facing a new situation today: Susan went to the store to buy some bags of ice for a party she was having later in the day. When she got home she put one bag of ice in the sink and another in the freezer, but then was distracted by a phone call and forgot to put the other bag in the freezer. When she returned, the bag of ice had melted. Thomas is a research assistant and has taken samples of rat liver enzymes that need to be stored overnight. He places one in refrigerated storage, but forgot one and left it out on the counter top. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will the refrigerated sample have a lower or higher average kinetic energy than the sample on the counter?
A: lower
Question: 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 465C (860F). That's hot enough to melt lead! I am facing a new situation today: Brad and Joe studied atmospheric conditions on different planets of our solar system. Joe studied about Earth, while Brad studied more about Venus. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person learned about the planet with a thinner atmosphere?
Answer: Joe
[Q]: I read this background article the other day: One reason radiation is dangerous is that it can't be detected with the senses. You normally can't see it, smell it, hear it, or feel it. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one in Figure below , has a tube that contains atoms of a gas. If radiation enters the tube, it turns gas atoms to ions that carry electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. I am facing a new situation today: David was visiting Japan. First, he went to Fukushima where the recent nuclear plant disaster happened. He found the city still had very high radiation. Then he visited Hiroshima. He found that Hiroshima had some low radiation. Finally, he visited the capital city Tokyo. He found that Tokyo did not have any radiation. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: In Hiroshima would a Geiger counter click faster or slower than Fukushima?
****
[A]: slower
input: Please answer the following: I read this background article the other day: An anaerobic organism is any organism that does not need oxygen for growth and even dies in its presence. Obligate anaerobes will die when exposed to atmospheric levels of oxygen. Clostridium perfringens bacteria, which are commonly found in soil around the world, are obligate anaerobes. Infection of a wound by C. perfringens bacteria causes the disease gas gangrene. Obligate anaerobes use molecules other than oxygen as terminal electron acceptors. I am facing a new situation today: Microbiologist John is studying the anaerobic organism. He collected two samples of this organism, sample A and sample B. Sample A is an anaerobic organism, and sample B is specifically identified as the Clostridium perfringens obligate anaerobe. To compare these samples to other organisms he collected another microbe that is not an anaerobic organism. He labeled it as sample C. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which sample might not die in presence of oxygen, sample A or sample C?
++++++++++
output: sample C
I read this background article the other day: Old age begins in the mid-60s and lasts until the end of life. Many people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common. I am facing a new situation today: Megan, a sophomore in college, is visiting her grandparents who live out of town. There is a party going on at her grandparents' house because her grandma, Emily, has just retired. There is cake and ice cream and people are talking about their jobs, and Emily is talking about all the good and bad memories she has from her work. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who will have quicker reflexes?

Answer:
Megan
