Problem: Given the question: 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. Given the paragraph above, please answer correctly the following question: Which country had more people transmitting HIV by contact with infected semen? Hint: 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/ .

Problem: Given the question: Two groups f people presented allergy symptoms. Group Alpha inhaled some allergens, but they were in a very protected environment, while Group Beta ingested some allergens and was exposed to a wide variety of other allergens. Given the paragraph above, please answer correctly the following question: Which group had some people that were exposed to dust mites? Hint: An allergy is a disease in which the immune system makes an inflammatory response to a harmless antigen . Any antigen that causes an allergy is called an allergen. Allergens may be inhaled or ingested, or they may come into contact with the skin. Two common causes of allergies are shown in Figure below . Inhaling ragweed pollen may cause coughing and sneezing. Skin contact with oils in poison ivy may cause an itchy rash. Other common causes of allergies include dust mites, mold, animal dander, insect stings, latex, and certain food and medications. Symptoms of a common allergy such as pollen can include sneezing, a runny nose, nasal congestion and itchy, watery eyes.

Problem: Given the question: People in Iran used extensive grazing, fell most of their trees so they have lots of problems with desertification. Iraq took a more mindful approach to land use, they preserved native species, planted trees and didn't overgraze the land. Given the paragraph above, please answer correctly the following question: Which country destroyed less land through human activity? Hint: Desertification is a type of land degradation in which a relatively dry area of land becomes a desert, typically losing its bodies of water as well as vegetation and wildlife.[2] It is caused by a variety of factors, such as through climate change (particularly the current global warming)[3] and through the overexploitation of soil through human activity.[4] When deserts appear automatically over the natural course of a planet's life cycle, then it can be called a natural phenomenon; however, when deserts emerge due to the rampant and unchecked depletion of nutrients in soil that are essential for it to remain arable, then a virtual "soil death" can be spoken of,[5] which traces its cause back to human overexploitation. Desertification is a significant global ecological and environmental problem with far reaching consequences on socio-economic and political conditions.[6]
