Problem: Given the question: The police arrested two homeless people. James was 35 and had been HIV positive for 20 years, and Bill, who was 54 and was not HIV positive. They booked them and let them go.  Given the paragraph above, please answer correctly the following question:   Which person had to take medicines to slow down the virus?  Hint: 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.

James


Problem: Given the question: David is trying to understand temperature and the science behind it. He took two objects, object A and object B, to his physics professor. Object A had higher temperature, but object B had lower temperature. His physics professor explained him why one object's temperature was higher while other object's temperature was lower.  Given the paragraph above, please answer correctly the following question:   Which object would have less average kinetic energy, object A or object B?  Hint: 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.

The answer is:
object B


Problem: Given the question: Dr. Smith studied a group of people under 65 called group I, and a group of people over 65 called group II. Old age signs were more obvious after the age of 65.  Given the paragraph above, please answer correctly the following question:   Which had more people freeing up their time for grandchildren?  Hint: Old age begins in the mid-60s and lasts until the end of life. Many people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer’s disease that cause loss of mental function also become more common.
