Q: Many countries have attempted to reduce the human impact on climate change by reducing their emission of what greenhouse gas? Read this paragraph and choose the correct option from the provided answers: Efforts to control population growth led to the one-child policy in China, which used to include more severe consequences, but now imposes fines on urban couples who have more than one child. Due to the fact that some couples wish to have a male heir, many Chinese couples continue to have more than one child. The policy itself, its social impacts, and the effectiveness of limiting overall population growth are controversial. In spite of population control policies, the human population continues to grow. At some point the food supply may run out because of the subsequent need to produce more and more food to feed our population. The United Nations estimates that future world population growth may vary from 6 billion (a decrease) to 16 billion people by the year 2100. There is no way to know whether human population growth will moderate to the point where the crisis described by Dr. Ehrlich will be averted. Another result of population growth is the endangerment of the natural environment. Many countries have attempted to reduce the human impact on climate change by reducing their emission of the greenhouse gas carbon dioxide. However, these treaties have not been ratified by every country, and many underdeveloped countries trying to improve their economic condition may be less likely to agree with such provisions if it means slower economic development. Furthermore, the role of human activity in causing climate change has become a hotly debated socio-political issue in some developed countries, including the United States. Thus, we enter the future with considerable uncertainty about our ability to curb human population growth and protect our environment. Choices: - methane - acid dioxide - nitrous oxide - carbon dioxide A:
(Answer)
carbon dioxide

Ques:Q: Decreasing the volume of a gas and keeping everything else the same will cause its pressure to change in what way? Read this paragraph and choose the correct option from the provided answers: When gas molecules bump into things, it creates pressure. Pressure is greater when gas molecules occupy a smaller space, because greater crowding results in more collisions. This explains why decreasing the volume of a gas increases its pressure. Choices: - heat up - decrease - lower - increase A:

Ans:increase

Q: Condensation, melting, deposition, sublimation, vaporization, and freezing are all considered changes in what? Read this paragraph and choose the correct option from the provided answers: Changes of state are physical changes in matter. They are reversible changes that do not involve changes in matter's chemical makeup or chemical properties. Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization. These changes are shown in Figure below . Each is described in detail below. Choices: - density - altitude - speed - state A:
state
