Problem: Given the question: I read this background article the other day: The Human Immunodeficiency Virus ( HIV ) is the virus that causes Acquired Immunodeficiency Syndrome ( AIDS ). Most researchers believe that the HIV originated in sub-Saharan Africa during the 20th century. HIV is transmitted by sexual contact and by contact with infected bodily fluids, such as blood, semen, breast milk, and vaginal secretions. It is also passed from mother to fetus. HIV is now a pandemic , with an estimated (as of 2008) 38.6 million people now living with the disease worldwide. It is estimated that AIDS has killed more than 25 million people since it was first recognized in 1981. For further information about HIV/AIDS, see the CDC (Centers for Disease Control and Prevention) web site at http://www.cdc.gov/hiv/resources/factsheets/ . I am facing a new situation today: Sam and Ned went on vacation, The 2 friends partied nights and spent their days on the beach. Sam started getting flu like symptoms, so he went to the doctor's office where he found out that he was infected with HIV. Ned got scared when he heard what happened, but fortunately he was OK. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend caught a virus that is transmitted by contact with semen?
++++++++++++++++++++++++++++++++
The answer is:
Sam
input question: I read this background article the other day: Recall that air pollution is due to chemical substances and particles released into the air mainly by human actions. When most people think of air pollution, they think of the pollution outdoors. But it is just as easy to have indoor air pollution. Your home or school classroom probably doesn't get much fresh air. Sealing up your home reduces heating and cooling costs. But this also causes air pollution to stay trapped indoors. And people today usually spend a majority of their time indoors. So exposure to indoor air pollution can become a significant health risk. I am facing a new situation today: Two twin sisters, Bianca and Rosa, were exposed to high levels of air pollution. While Bianca was exposed mostly to indoor pollution, Rosa was heavily exposed to outdoor pollution. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which sister was less exposed to home air pollution????
output answer: Rosa
I read this background article the other day: As a liquid is heated, the average kinetic energy of its particles increases. The rate of evaporation increases as more and more molecules are able to escape the liquid's surface into the vapor phase. Eventually a point is reached when the molecules all throughout the liquid have enough kinetic energy to vaporize . At this point the liquid begins to boil. The boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure. The Figure below illustrates the boiling of liquid. I am facing a new situation today: Alexander is heating up water in his kitchen because he is preparing to make pasta. He has split the water into two containers, container A and container B. Container A has been heating up for a long amount time, while container B has only been heating up for a short amount of time. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which container has a lower rate of evaporation?
----
Answer: container B

I am facing a new situation today: Two neighboring countries had health epidemics. While Ghana had a measles problem, Niger had a very serious HIV problem that seemed to get out of control. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country had fewer people at risk of getting AIDS?
A: Ghana
Question: I read this background article the other day: A few insects, such as mayflies and some moths, never eat. That's because their lives are over in just a few hours or days. Once these insects become adults, they lay eggs, and then die. On the other hand, some insects are very healthy eaters. A silkworm eats enough leaves to increase its weight more than 4,000 times in just 56 days, as the silkworm increases in size about 10,000 times since birth. A locust eats its own weight in plants every day. Just imagine eating your own weight in food every day. You probably couldn't. You would most likely get very sick even if you tried. I am facing a new situation today: Two entomologists liked studying all types of insects and arthropods. Bill was focused on insects that never eat. His buddy Paul was more focused on the feeding habits of other insects that eat a lot of food. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend studied fewer locusts?
Answer: Bill
Please answer this: I read this background article the other day: Antifreeze could also be called "antiboil" because it also raises the boiling point of the water in a car radiator. Hot weather combined with a hot engine can easily raise the temperature of the water in the radiator above 100 C, which is the boiling point of pure water. If the water boils, it could cause the engine to overheat and become seriously damaged. However, if antifreeze has been added to the water, the boiling point is much higher. For example a 50 percent antifreeze solution has a boiling point of 129 C. Unless the water gets hotter than this, it won't boil and ruin the engine. I am facing a new situation today: Rob is an auto mechanic. He was checking the radiators of his car and truck. He put antifreeze into the car radiator, but didn't put any antifreeze into the truck radiator. He was wondering how the vehicles would fare in coming hot weather. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would the car's engine less likely or more likely be damaged than truck's engine?
++++++++
Answer:
less likely
