Answer the following question given this paragraph: The Galapagos Islands are a group of 16 volcanic islands 600 miles off the west coast of South America. The islands are famous for their many species found nowhere else. It was on these islands where Darwin began to develop his theory of evolution. Q: The galapagos islands are a group of 16 volcanic islands 600 miles off the west coast of what continent? Choices: - north america - europe - asia - south america A:
**Answer**
south america

Answer the following question given this paragraph: Compared to Earth, the solar system is a big place. But galaxies are bigger - a lot bigger. A galaxy is a very large group of stars held together by gravity. How enormous a galaxy is and how many stars it contains are impossible for us to really understand. A galaxy contains up to a few billion stars! Our solar system is in the Milky Way Galaxy. It is so large that if our solar system were the size of your fist, the galaxy's disk would be wider than the entire United States! There are several different types of galaxies, and there are billions of galaxies in the universe. Q: What galaxy is our solar system a part of? Choices: - Centaurus - Andromeda - Bode's Galaxy - milky way A:
**Answer**
milky way

Answer the following question given this paragraph: Later, a true coelom evolved. This is a fluid-filled body cavity that is completely enclosed by mesoderm. The coelom lies between the digestive cavity and body wall. You can see it in the invertebrate in Figure below . Modern invertebrates with a coelom include mollusks (Phylum Mollusca) and annelids (Phylum Annelida). Q: What is a fluid-filled body cavity that is completely enclosed by mesoderm called? Choices: - pseudocoelom - hymenium - choroid - coelom A:
**Answer**
coelom

Answer the following question given this paragraph: A type of work called expansion work (or pressure-volume work) occurs when a system pushes back the surroundings against a restraining pressure, or when the surroundings compress the system. An example of this occurs during the operation of an internal combustion engine. The reaction of gasoline and oxygen is exothermic. Some of this energy is given off as heat, and some does work pushing the piston in the cylinder. The substances involved in the reaction are the system, and the engine and the rest of the universe are the surroundings. The system loses energy by both heating and doing work on the surroundings, and its internal energy decreases. (The engine is able to keep the car moving because this process is repeated many times per second while the engine is running. ) We will consider how to determine the amount of work involved in a chemical or physical change in the chapter on thermodynamics. Q: What type of work called occurs when a system pushes back the surroundings against a restraining pressure? Choices: - shape work - contrast work - retention work - expansion work A:
**Answer**
expansion work
