Problem: Given the question: I can use this background: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ).  Now, I have a new situation: Two soccer players had a friendly match one on one after work. Paul had plenty of time to do his warm up properly, but John got there late and didn't warm up. Paul won the match.  Answer this question please: Which player was more exposed to muscle injuries?

The answer is:
John


Problem: Given the question: I can use this background: Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes.  Now, I have a new situation: Two neighboring counties, Brown and Green county, had different weather patterns occur last month. The weather in Brown county was quite stable, but green county experienced atmospheric convection and other related phenomena.  Answer this question please: Which county had more cumulus clouds forming?
++++++++++++++++++++++++++++++++
The answer is:
Green


Problem: Given the question: I can use this background: 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/ .  Now, I have a new situation: Monica and Jill are two friends. They study and party together most of the time. One day Monica shared a needle with a drug addict at a party. She later found out that she'd been infected with HIV. Jill was scared and helped her as much as she could.  Answer this question please: Which friend  has the virus that causes Acquired Immunodeficiency Syndrome?
++++++++++++++++++++++++++++++++
The answer is:

Monica
