Q: I can use 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. Now, I have a new situation: Two neighboring countries implemented different sets of economic reforms. The reforms took over a decade to implement, but the effects were not similar at all. Redvania was more prosperous and it became much richer, while Blueland stagflated and the inhabitants were not pleased with the outcome. Answer this question please: Which country was much happier after 10 years?
A: Redvania

Q: I can use this background: The frequency of a wave is the same as the frequency of the vibrations that caused the wave. For example, to generate a higher-frequency wave in a rope, you must move the rope up and down more quickly. This takes more energy, so a higher-frequency wave has more energy than a lower-frequency wave with the same amplitude. You can see examples of different frequencies in the Figure below (Amplitude is the distance that particles of the medium move when the energy of a wave passes through them.) Now, I have a new situation: John was tuning his musical instruments with two tuning forks, fork A and fork B. He produced higher frequency with fork A and lower frequency with fork B. Interestingly, both frequencies had the same amplitude. Answer this question please: Which fork John needed to move more quickly, fork A or fork B?
A: fork A

Q: I can use this background: There are many examples in the chemical world of changes in entropy. Phase transitions are one obvious example. When a substance makes a transition from the liquid state to the gaseous state, the particles have many more possible arrangements, because they are no longer confined to a specified volume in which they are close to each other; gas particles can move freely throughout their container. Vaporization represents an increase in entropy. In the opposite direction, a liquid loses entropy when it freezes to a solid. Because solids have very ordered structures, there are fewer possible arrangements of particles that would result in the properties associated with a solid. Now, I have a new situation: A boy is sitting at the side of the lake catching some fish when his dad begins to explain to him that the water he is fishing in is actually continuously evaporating into the air and turning into a gas. The water he is fishing in will eventually turn into the clouds that he sees in the sky. Answer this question please: Does entropy increase or decrease as the water turns into clouds?
A: increase

Q: 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. Now, 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. Answer this question please: Which researcher found less carbon dioxide in the atmosphere?
A:
Tim
