Please answer this: I have a new situation: Tom and Andy are two old friends. Tom was infected with HIV 20 years ago, and Andy has been helping him ever since. Andy is as healthy as an ox. But I can use this background: 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. What is an answer for this question: Which friend cannot have the development of AIDS delayed with proper medicine?
++++++++
Answer: Andy

Please answer this: I have a new situation: Long island was full of people and they used all their natural resources and burned fossil fuels while Snail island protected the environment and had fewer people living there. But I can use this background: Pollutants also affect the atmosphere through their contribution to global warming. Global warming is an increase in the Earth's temperature. It is thought to be caused mostly by the increase of greenhouse gases like carbon dioxide. Greenhouse gases can be released by factories that burn fossil fuels. Over the past 20 years, burning fossil fuels has produced about three-quarters of the carbon dioxide from human activity. The rest of the carbon dioxide in the atmosphere is there because of deforestation, or cutting down trees ( Figure below ). Trees absorb carbon dioxide during cellular respiration, so when trees are cut down, they cannot remove carbon dioxide from the air. What is an answer for this question: Which island produced more pollutants?
++++++++
Answer: Long

Please answer this: I have a new situation: A geologist is examining rocks found in neighboring cities. City A recently experienced heavy rainfall for several weeks. Meanwhile, city B hasn't had a single rainy day in the same time span. But I can use this background: Rainfall in an area is important because it influences the rate of weathering. More rain means that more rainwater passes through the soil. The rainwater reacts chemically with the particles. The top layers of soil are in contact with the freshest water, so reactions are greatest there. High rainfall increases the amount of rock that experiences chemical reactions. High rainfall may also carry material away. This means that new surfaces are exposed. This increases the rate of weathering. What is an answer for this question: Which city would have had more rock and soil material carried away by the rain?
++++++++
Answer:
City A
