input question: You are given a new situation: A group of researches studied the green house gas emissions and their effects on Earth and people during the eighties compared to the twenties. and a hint : Current Situation : Currently the heating effect of extra greenhouse gases (since the start of the industrial revolution) is equal to about . Thus the recent period has recorded parallel increases in concentration of carbon dioxide and average global temperature. As more greenhouse gases are put into the atmosphere the temperature will increase further. There are certain effects of a warmer Earth (discussed more in optional section), which could accelerate the process, even if no more greenhouse gases are put into the atmosphere (an unlikely prospect for the foreseeable future). Please answer this question : During which decade did Earth experience a less prevalent heating effect because of green house gas emissions????
output answer: twenties

input question: You are given a new situation: Rob was in his chemistry lab, experimenting with different states of matter. He had a liquid substance that he labeled as state A. He then transformed half of the liquid substance to gaseous state. He labeled it as state B. Finally, he froze the remaining half of the liquid to solid state. He labeled it as state C. and a hint : 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. Please answer this question : Which does not represent an increase in entropy, state A or state B????
output answer: state A

input question: You are given a new situation: Two neighboring cities had very different health related problems. Twin city had increased air pollution, their people experiencing all kinds of respiratory diseases, while Pine city had problems with age related diseases. and a hint : Recall that air pollution is due to chemical substances and particles released into the air mainly by human actions. When most people think of air pollution, they think of the pollution outdoors. But it is just as easy to have indoor air pollution. Your home or school classroom probably doesn't get much fresh air. Sealing up your home reduces heating and cooling costs. But this also causes air pollution to stay trapped indoors. And people today usually spend a majority of their time indoors. So exposure to indoor air pollution can become a significant health risk. Please answer this question : Which city had fewer people exposed to chemical substances released into the air by human actions????
output answer: Pine

input question: You are given a new situation: two groups of students studied animal reproduction. Group Alpha studied sexual reproduction, while group Beta studies asexual reproduction. and a hint : All living organisms must have the ability to reproduce. Living things make more organisms like themselves. Whether the organism is a rabbit, or a tree, or a bacterium, life will create more life. If a species cannot create the next generation, the species will go extinct. Reproduction is the process of making the next generation and may be a sexual or an asexual process. Sexual reproduction involves two parents and the fusion of gametes , haploid sex cells from each parent. Sexual reproduction produces offspring that are genetically unique and increases genetic variation within a species. Asexual reproduction involves only one parent. It occurs without a fusion of gametes and produces offspring that are all genetically identical to the parent. Please answer this question : Which group of students learned more about the fusion of gametes????
output answer:
Beta
