Problem: Given the question: I read this background article the other day: Something that is elastic can return to its original shape after being stretched or compressed. This property is called elasticity . As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force . The farther the material is stretched or compressed, the greater the elastic force becomes. As soon as the stretching or compressing force is released, elastic force causes the material to spring back to its original shape. You can watch a demonstration of elastic force at this URL: I am facing a new situation today: An inventor named Nelly is tinkering around in her home office where she has created two new types of material that could be used in products. The first one she is calling Glubber, and the second she has named Malk. To try to figure out what type of products these new materials may be used for, Nelly is performing various tests. The first test she is doing is securing one end of the material to a table and then pulling on it and letting it go. When she performs this test on some Glubber, the material quickly snaps back toward the table. Performing the same process with some Malk, the material slowly crawls along the floor as it makes its way back to the table. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: In Nelly's experiment, which material exerted more elastic force?

The answer is:
Glubber
input question: I read this background article the other day: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk. I am facing a new situation today: Two teams of researchers studied the environment in Antarctica. Team Black studied air pollution and the ozone layer, Team Red studied the water. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which team didn't observe that the culprit are chlorine gasses????
output answer: Red
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: Justin and Robert are brothers who recently went to the doctor for their yearly physical. They wanted to know if they had any future health risks. The doctor asked them about their health habits. Justin told the doctor that he has smoked regularly for a long time, while Robert mentioned that he has never smoked. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who has a lower risk of getting lung cancer?
----
Answer: Robert
Q: I read this background article the other day: During Amniocentesis a small amount of amniotic fluid, which contains fetal cells, is extracted from the amnion or amniotic sac surrounding a developing fetus, and the fetal DNA is examined for genetic abnormalities. Amniocentesis is not performed for every pregnancy, but is generally done when an increased risk of genetic defects in the fetus is indicated, by mother's age (over 35 years is common), family history of genetic defects, or other factors. I am facing a new situation today: David is a doctor with the city hospital. Today, he is seeing four patients, patient A, patient B, patient C, and patient D. All four patients are expectant mothers. Moreover, patient A is over thirty five years old, but patient B is under thirty five years old. Patient C has family history of genetic disorder, but patient D does not have any family history of genetic disorder. David needs to prescribe appropriate treatment according to each patient's condition. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would patient C be less or more at risk of genetic defects in the fetus than patient D?
A: more
Question: I read this background article the other day: Thermoclines, or sudden changes in temperature. Where the air temperature is higher than the water temperature, shallow water may be warmed by the air and the sunlight but deeper water remains cold resulting in a lowering of temperature as the diver descends. This temperature change may be concentrated over a small vertical interval, when it is called a thermocline.[3][4] Where cold, fresh water enters a warmer sea the fresh water may float over the denser saline water, so the temperature rises as the diver descends.[3] In lakes exposed to geothermal activity, the temperature of the deeper water may be warmer than the surface water. This will usually lead to convection currents.[3] I am facing a new situation today: The underwater fishing teams picked their spots early. Team Bob went at the mouth of the river, where the freshwater met the salty seawater in the hope that more turbidity from the river and more nutrients will attract more fish. Team Dan went south where they knew there was less of a thermocline, so they could catch fish without taking risks. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which team had more chances to catch fish?
Answer: Bob
Please answer this: I read this background article the other day: Chlamydia may cause a burning feeling during urination. It may also cause a discharge (leaking of fluids) from the vagina or penis. But in many cases it causes no symptoms. As a result, people do not know they are infected, so they don't go to the doctor for help. If chlamydia goes untreated, it may cause more serious problems in females. It may cause infections of the uterus, fallopian tubes, or ovaries. These infections may leave a woman unable to have children. I am facing a new situation today: At a doctor's office, two people come in to get STD tests. John comes in and reports the only symptom he has is a rash on his thighs. Patty says she has seen something leaking out of her vagina, and she's not sure what it is. The doctor takes a urine sample from each and will give them the results in a day or two. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Is Patty more or less likely than John to experience a burning sensation while urinating?
