input: OPTIONS:
- electrolysis fuel
- polymerization fuel
- nuclear fue
- hydrocarbon fuel Now, answer this question: Answer the following question given this paragraph: It is hard to overstate the importance of hydrocarbons to modern life. Hydrocarbons have even been called the "driving force of western civilization. " You saw some ways they are used in the opening image. Several other ways are pictured in the Figure below . The most important use of hydrocarbons is for fuel. Gasoline, natural gas, fuel oil, diesel fuel, jet fuel, coal, kerosene, and propane are just some of the commonly used hydrocarbon fuels. Hydrocarbons are also used to make things, including plastics and synthetic fabrics such as polyester. Q: Gasoline, natural gas, fuel oil, diesel fuel, jet fuel, coal, kerosene, and propane are examples of what type of fule? A:
A:
output: hydrocarbon fuel

Answer the following question given this paragraph: Some of the best known types of fungi are mushrooms, which can be edible or poisonous ( Figure below ). Many species are grown commercially, but others are harvested from the wild. When you order a pizza with mushrooms or add them to your salad, you are most likely eating Agaricus bisporus , known as white or button mushrooms, the most commonly eaten species. Other mushroom species are gathered from the wild for people to eat or for commercial sale. Many mushroom species are poisonous to humans. Some mushrooms will simply give you a stomachache, while others may kill you. Some mushrooms you can eat when they are cooked but are poisonous when raw. So if you find mushrooms in the wild, don't eat them until you are certain they are safe!. Q: Mushrooms are an example of what type of organism, which includes beneficial and toxic specimens? A:
****
A: fungi

Answer the following question given this paragraph: Ionic substances are completely held together by ionic bonds. The full charges of the ions (for example, Na + and Cl - in sodium chloride) cause electrostatic interactions that result in a stable crystal lattice. We saw in the previous chapter that most ionic compounds have high melting points, are brittle, are often soluble in water, and conduct electricity when melted or dissolved in water. Ionic compounds exist as extended, orderly arrangements of ions. As we will see, this is quite different from the structure of molecular substances, which take the form of collections of individual molecules. The atoms within a molecule are held very strongly together, but the interactions between different molecules are significantly weaker. Q: What are ionic substances completely held together by? A:
OPTIONS:
- thermal bonds
- localized bonds
- magnetic bonds
- ionic bonds
ionic bonds

Answer the following question given this paragraph: Every object is attracted to every other object by gravity. The force of gravity between two objects depends on the mass of the objects. It also depends on how far apart the objects are. When you are sitting next to your dog, there is a gravitational force between the two of you. That force is far too weak for you to notice. You can feel the force of gravity between you and Earth because Earth has a lot of mass. The force of gravity between the Sun and planets is also very large. This is because the Sun and the planets are very large objects. Gravity is great enough to hold the planets to the Sun even though the distances between them are enormous. Gravity also holds moons in orbit around planets. Q: Every object is attracted to every other object by what force? A:
OPTIONS:
- weight
- magnetism
- pheromones
- gravity

Answer:
gravity
