Please answer this: I read this background article the other day: The dangers of global warming are being increasingly studied by a wide global consortium of scientists. These scientists are increasingly concerned about the potential long-term effects of global warming on our natural environment and on the planet. Of particular concern is how climate change and global warming caused by anthropogenic, or human-made releases of greenhouse gases, most notably carbon dioxide, can act interactively, and have adverse effects upon the planet, its natural environment and humans' existence. It is clear the planet is warming, and warming rapidly. This is due to the greenhouse effect, which is caused by greenhouse gases, which trap heat inside the Earth's atmosphere because of their more complex molecular structure which allows them to vibrate and in turn trap heat and release it back towards the Earth. This warming is also responsible for the extinction of natural habitats, which in turn leads to a reduction in wildlife population.The most recent report from the Intergovernmental Panel on Climate Change (the group of the leading climate scientists in the world) concluded that the earth will warm anywhere from 2.7 to almost 11 degrees Fahrenheit (1.5 to 6 degrees Celsius) between 1990 and 2100. I am facing a new situation today: Rob was evaluating two research studies on climate change, study A and study B. Study A explained how increased greenhouse gases would affect the climate. On the other hand, study B showed how decreased greenhouse gases would affect the climate. Rob found the studies very interesting. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: In which study more heat would be trapped inside the Earth's atmosphere, study A or study B?
++++++++
Answer: study A
Problem: I read this background article the other day: HIV , or human immunodeficiency virus, causes AIDS. AIDS stands for "acquired immune deficiency syndrome." It is a condition that causes death and does not have a known cure. AIDS usually develops 10 to 15 years after a person is first infected with HIV. The development of AIDS can be delayed with proper medicines. The delay can be well over 20 years with the right medicines. Today, individuals who acquire HIV after 50 years of age can expect to reach an average human life span. I am facing a new situation today: Tom and Andy are two old friends. Tom was infected with HIV 20 years ago, and Andy has been helping him ever since. Andy is as healthy as an ox. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend has a disease without cure?

A: Tom
Problem: Given the question: I read this background article the other day: Middle adulthood lasts from the mid-30s to the mid-60s. During this stage of life, many people raise a family and strive to attain career goals. They start showing physical signs of aging, such as wrinkles and gray hair. Typically, vision, strength and reaction time start declining. Diseases such as type 2 diabetes, cardiovascular or heart disease, and cancer are often diagnosed during this stage of life. These diseases are also the chief causes of death in middle adulthood. I am facing a new situation today: Pat and Tammy are mother and sister. They like to take long walks together. Pat is 60, while Tammy is 32 years-old. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person shows more gray hair?
++++++++++++++++++++++++++++++++
The answer is:
Pat
input question: I read this background article the other day: Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane with two carbon atoms. The chemical formulas and properties of methane, ethane, and other small alkanes are listed in the Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally boil and melt at higher temperatures. I am facing a new situation today: Two students studied chemistry. Nate studied alkanes, and Ben studied noble gasses. They both got an A later on. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student learned less about methane????
output answer: Ben
I read this background article the other day: Cholesterol can't dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. Low-density lipoprotein, or LDL, is known as "bad" cholesterol. High-density lipoprotein (HDL) is known as good cholesterol. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances, it can form plaque, and lead to atherosclerosis. If a clot forms and blocks a narrowed artery, a heart attack or stroke can result. Cholesterol comes from the food you eat as well as being made by the body. To lower bad cholesterol, a diet low in saturated fat and dietary cholesterol should be followed. Regular aerobic exercise also lowers LDL cholesterol and increases HDL cholesterol. I am facing a new situation today: Manny and Joe checked their cholesterol levels. Joe found out that his cholesterol levels were within normal parameters, while Manny had very high cholesterol levels and was recommended some lifestyle changes. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person was at a higher risk of experiencing a heart attack?
----
Answer: Manny
Q: 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 high school buddies, Dan and Bob, had very different lifestyles 30 years later. Dan made only healthy lifestyle choices, was vegan. Bob ate meat, cheese and didn't care about his health and didn't protect himself. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which man was exposed to a higher risk of cancer, Dan or Bob?
A:
Bob
