Please answer this: I have a new situation: Two researchers looked at the human influence on atmospheric carbon dioxide levels. Tim studied a human settlement from 10000 years ago, while Bob studied a present day county. Today's economy in the county revolved around extensive agriculture. But I can use this background: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs. What is an answer for this question: Which researcher didn't find that human activities reduced the number of autotrophic organisms?

Answer: Tim

Please answer this: I have a new situation: Bob was a medical student and he studied drugs administered to people with viral diseases, while his colleague Liam decided to study other types of drugs, such as antibiotics and anticoagulants. But I can use this background: While people have been able to prevent certain viral diseases by vaccinations for many hundreds of years, the development of antiviral drugs to treat viral diseases is a relatively recent development. Antiviral drugs are medications used specifically for treating the symptoms of viral infections. The first antiviral drug was interferon , a substance that is naturally produced by certain immune cells when an infection is detected. Over the past twenty years the development of antiretroviral drugs (also known as antiretroviral therapy, or ART) has increased rapidly. This has been driven by the AIDS epidemic. What is an answer for this question: Which colleague studied less about the development of antiviral drugs?

Answer: Liam

Please answer this: I have a new situation: Gary researched two old human settlements. Village A was smaller, it existed about 12,000 years ago. He also studied village B, which existed about 6,000 years ago. The village was much bigger and better developed. But I can use this background: Human beings invented agriculture about 10,000 years ago. This provided a bigger, more dependable food supply. It also allowed people to settle down in villages and cities for the first time. Birth rates went up because there was more food and settled life had other advantages. Death rates also rose because of crowded living conditions and diseases that spread from domestic animals. Because the higher birth rates were matched by higher death rates, the human population continued to grow very slowly. What is an answer for this question: Which village had higher death rates?
++++++++
Answer:
village B
