For each drop-down box, select the appropriate word from the drop down that best completes the sentence. Oil, or petroleum, is a versatile energy source used for transportation, heating, and electricity generation. It is primarily extracted through drilling wells and refining processes. While oil has fueled economic growth and mobility, its extraction, transportation, and combustion pose significant environmental risks, including oil spills and habitat destruction. Natural gas, consisting mainly of methane, is another abundant fossil fuel used for heating, electricity generation, and industrial processes. It is extracted through drilling and hydraulic fracturing, or fracking, techniques. While natural gas emits fewer pollutants than coal or oil, methane leakage during extraction and transportation is a potent greenhouse gas. Nuclear energy, generated through nuclear fission reactions, is another non-renewable energy source. Uranium, the fuel used in nuclear reactors, is mined from the Earth's crust and undergoes nuclear reactions to release heat energy. While nuclear power plants produce electricity without emitting greenhouse gases, they pose significant safety and environmental risks,
a) True
b) False
