Please answer this: Given the background: 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: and the situation: Andy is playing with a rubber band. He stretches the rubber band out as far as he can without breaking it Answer the following question: Given a spring, will compressing it down cause it to stay compressed or return to its original shape?
++++++++
Answer: original shape

Problem: Given the background: No doubt you already have a good idea of what temperature is. You might say that it's how warm or cool something feels. In physics, temperature is defined as the average kinetic energy of the particles of matter. When particles of matter move more quickly, they have more kinetic energy, so their temperature is higher. With a higher temperature, matter feels warmer. When particles move more slowly, they have less kinetic energy on average, so their temperature is lower. With a lower temperature, matter feels cooler. and the situation: Sarah just finished reheating two leftover chicken sandwiches in the microwave that she had made the previous night. She takes them out and leaves them on the kitchen counter while she pours herself a glass of wine. Her roommate, Carla, comes out and decides to take a more scientific approach toward the chicken sandwiches. Carla sees that the average kinetic energy in sandwich A is higher than the average kinetic energy in sandwich B. Carla then takes a big bite out of both sandwiches and returns to her room as if nothing happened. Answer the following question: Which sandwich was in the microwave for a longer period of time?

A: sandwich A

Problem: Given the question: Given the background: You don't have to suffer through an infection to gain immunity to some diseases. Immunity can also come about by vaccination. Vaccination is the process of exposing a person to pathogens on purpose so the person will develop immunity to them. In vaccination, the pathogens are usually injected under the skin. Only part of the pathogens are injected, or else weakened or dead pathogens are used. This causes an immune response without causing the disease. Diseases you are likely to have been vaccinated against include measles, mumps, and chicken pox. and the situation: Two families thought differently about vaccinations. Dean family vaccinated their children while Moore family didn't. Answer the following question: Which family exposed their members to pathogens on purpose?
++++++++++++++++++++++++++++++++
The answer is:
Dean

input question: Given the 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/ . and the 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 the following question: Which friend has a virus that is transmitted by sexual contact????
output answer: Monica

Given the background: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe. and the situation: Mary had two twin daughters, Mimi and Coco. Coco was healthy, but Mimi had hemophilia. Mimi took frequent trips to the doctor's office. Answer the following question: Which girl had the same disease as the royal families of Europe?
----
Answer: Mimi

Q: Given the background: In nature, when the population size is small, there is usually plenty of food and other resources for each individual. When there is plenty of food and other resources, organisms can easily reproduce, so the birth rate is high. As the population increases, the food supply, or the supply of another necessary resource, may decrease. When necessary resources, such as food, decrease, some individuals will die. Overall, the population cannot reproduce at the same rate, so the birth rates drop. This will cause the population growth rate to decrease. and the situation: Two neighboring countries of similar size and wealth of resources had different sized population. Deerland had a small population, while Bearland had a large population. Both peoples lived mostly off the land. Answer the following question: Which country had less food per individual?
A:
Bearland
