Answer:
Advantages: Wind turbines do not actively create green house gases, wind is an indirect solar energy (which means it never runs out), and it has a fairly high net energy
Disadvantages: NIMBY effect (not in my backyard, it means people support it, but they don't want to be near it), transportation and construction of materials cause greenhouse gases, and wind turbines can kill/harm birds and bats
Explanation:
Gathering, constructing and transporting materials to build wind turbines releases green house gases, because of vehicle's combustion and factory emissions. However, wind turbines rely on a renewable resource that a) never runs out, and b) is a clean source of energy. Compared to nonrenewable energy sources, wind is a good energy source.

Answer:
Hypothesis.
Explanation:
A hypothesis is a potential answer to that type of question that somehow can be tested. For example, if a hypothesis is that soft drinks aren't the cause of becoming fat. The answer to this hypothesis can be yes or no. But the result will come only after a valid test.
Usually, a hypothesis is taken as an assumption. For the testing purpose, the hypothesis is accepted. After testing, the result of a hypothesis might be true or false.
