Problem:OPTIONS:
- smaller blade area
- larger surface area
- larger surface area
- smaller surface area

Answer the following question given this paragraph: A large log placed in a fire will burn relatively slowly. If the same mass of wood were added to the fire in the form of small twigs, they would burn much more quickly. This is because the twigs provide a greater surface area than the log does. An increase in the surface area of a reactant increases the rate of a reaction. Surface area is larger when a given amount of a solid is present as smaller particles. A powdered reactant has a greater surface area than the same reactant as a solid chunk. In order to increase the surface area of a substance, it may be ground into smaller particles or dissolved into a liquid. In solution, the dissolved particles are separated from each other and will react more quickly with other reactants. Q: Why does a large log burn relatively slowly compared to the same mass of wood in the form of small twigs? A:
****
A: smaller surface area

Answer the following question given this paragraph: Examples of behaviors with annual cycles include migration and hibernation. Both are innate behaviors. They are triggered by changes in the environment, such as the days growing shorter in the fall. Q: Triggered by changes in the environment, migration and hibernation occur as cycles on what temporal basis? A:
OPTIONS:
- bi-annually
- seasonally
- monthly
- annual
annual

Answer the following question given this paragraph: The small intestine a is narrow tube that starts at the stomach and ends at the large intestine ( Figure above ). In adults, the small intestine is about 23 feet long. Chemical digestion takes place in the first part of the small intestine. Many enzymes and other chemicals are secreted here. The small intestine is also where most nutrients are absorbed into the blood. The later sections of the small intestines are covered with tiny projections called villi ( Figure below ). Villi contain very tiny blood vessels. Nutrients are absorbed into the blood through these tiny vessels. There are millions of villi, so, altogether, there is a very large area for absorption to take place. In fact, villi make the inner surface area of the small intestine 1,000 times larger than it would be without them. The entire inner surface area of the small intestine is about as big as a basketball court!. Q: Where does the small intestine begin? A:
OPTIONS:
- mouth
- colon
- spleen
- stomach

Answer: stomach

Question: Answer the following question given this paragraph: Seismograms contain a lot of information about an earthquake: its strength, length, and distance. Wave height is used to determine the magnitude of the earthquake. The seismogram shows the different arrival times of the seismic waves ( Figure below ). The first waves are P-waves since they are the fastest. S-waves come in next and are usually larger than P-waves. The surface waves arrive just after the S-waves. If the earthquake has a shallow focus, the surface waves are the largest ones recorded. Q: What measurement of the wave is used to determine the magnitude of an earthquake? A:
OPTIONS:
- length
- diameter
- width
- height
Answer: height

input with options: Answer the following question given this paragraph: Geysers are also created by water that is heated beneath the Earth's surface. The water may become superheated by magma. It becomes trapped in a narrow passageway. The heat and pressure build as more water is added. When the pressure is too much, the superheated water bursts out onto the surface. This is a geyser . Q: Geysers are created when what is heated beneath the earth's surface? A:
OPTIONS:
- magma
- gases
- air
- water
output: water

Problem: OPTIONS:
- prokaryotes
- growths
- ground beef
- protists
