Answer the following question given this paragraph: At a geothermal power plant, engineers drill wells into the hot rocks. Hot water or steam may come up through the wells. Alternatively, water may be put down into the well to be heated. It then comes up. The hot water or steam makes a turbine spin. This makes electricity. Pictured below is an example of a geothermal power plant ( Figure below ). Q: Drilling wells into hot rocks to release hot water or steam is an example of what kind of power plant? A:
OPTIONS:
- hydroelectric
- solar
- fossil fuel
- geothermal

Answer: geothermal

Answer the following question given this paragraph: Introduction Genetics is the study of heredity. Johann Gregor Mendel set the framework for genetics long before chromosomes or genes had been identified, at a time when meiosis was not well understood. Mendel selected a simple biological system and conducted methodical, quantitative analyses using large sample sizes. Because of Mendel's work, the fundamental principles of heredity were revealed. We now know that genes, carried on chromosomes, are the basic functional units of heredity with the capability to be replicated, expressed, or mutated. Today, the postulates put forth by Mendel form the basis of classical, or Mendelian, genetics. Not all genes are transmitted from parents to offspring according to Mendelian genetics, but Mendel's experiments serve as an excellent starting point for thinking about inheritance. Q: What is the study of heredity called? A:
OPTIONS:
- geriatrics
- heretics
- pediatrics
- genetics

Answer:
genetics
