Please answer this: Background: Using longitudinal data from over 100 countries, Diener and his colleagues showed that rich countries are in general happier than poor countries (Diener, Tay, & Oishi, 2013).[17] Also, life satisfaction for most countries goes up as they become wealthier over time. Diener identified three factors that influence the relationship between income and SWB. Namely, rising income most likely results in higher SWB when it leads to greater optimism, financial satisfaction and household material prosperity among citizens. Furthermore, Diener and his colleagues investigated the relationship between income and different elements of SWB. They illustrated that income has stronger influence on people's evaluation of their lives than the positive or negative emotions they experience over time (Diener, Kahneman, Tov, & Arora, 2010).[18] The study points to the necessity to evaluate different elements of SWB separately instead of treating happiness as a single entity.

Please answer this: Background: Soon after the original study was published, other researchers tried to replicate the research. However, it could not be replicated. No other studies could find a link between the vaccine and autism. As a result, scientists became convinced that the original results were incorrect. Eventually, investigators determined that the original study was a fraud. They learned that its author had received a large amount of money to find evidence that the vaccine causes autism, so he faked his research results. If other scientists had not tried to replicate the research, the truth might never have come out. You can read more about this case at the URL below. Paragraph: John works for the NSF. He has two research proposals in front of him, case A and case B. Both are looking for further funding. Case A research has been replicated by other researchers, but case B research could not be replicated by others. He needs to decide which research should get further funding. Given the paragraph above, please answer correctly the following question: In which case the scientist would have less likely committed a fraud, case A or case B?
++++++++
Answer: case A

Please answer 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. Paragraph: A team of archaeologists studied two human settlements, village Alpha from about 11000 years ago and village Beta, which existed 9000 years ago. Village Beta was bigger, because their inhabitants already knew about and practiced agriculture. Given the paragraph above, please answer correctly the following question: Which village had a less dependable food supply?
++++++++
Answer:
