Q: Answer the following question given this paragraph: Biomass is another renewable source of energy. Biomass includes wood, grains, and other plant materials or waste materials. People can burn wood directly for energy in the form of heat. Biomass can also be processed to make biofuel. Biofuel is a fairly new type of energy that is becoming more popular. Biomass is useful because it can be made liquid. This means that they can be used in cars and trucks. Some car engines can be powered by pure vegetable oil or even recycled vegetable oil. Sometimes the exhaust from these cars smells like French fries!. Q: Biomass can also be processed to make what kind of fuel? A:

OPTIONS:
- hydrogen fuel
- gasoline
- fossil
- biofuel

A: biofuel

input: OPTIONS:
- sense danger
- produce food
- fight infection
- digest food Now, answer this question: Answer the following question given this paragraph: The appendix is a tiny remnant of a once-larger organ. In a distant ancestor, it was needed to digest food. If your appendix becomes infected, a surgeon can remove it. You won't miss it because it no longer has any purpose in the human body. Q: What was the appendix used for in the past but is no longer needed for? A:

Q: Answer the following question given this paragraph: Bears get their energy from their food. Brown bears eat a varied diet, from nuts and berries to fish and other animals. When bears eat a berry, they are obtaining energy that the plant originally captured from the sun.

A:
Answer: sun

Problem:OPTIONS:

Answer the following question given this paragraph: The blood also carries hormones, which are chemical messenger molecules produced by organs of the endocrine system, through your body. Hormones are produced in one area of your body and have an effect on another area. To get to that other area, they must travel through your blood.
