Problem:OPTIONS:
- primary succession
- typical succession
- tertiary succession
- secondary succession

Answer the following question given this paragraph: Sometimes ecological succession occurs in areas where life has already existed. These areas already have soil full of nutrients. Secondary succession is the type of succession that happens after something destroys the habitat, such as a flood or other natural disaster. Abandoning a field that was once used for agriculture can also lead to secondary succession ( Figure below ). In this case, the pioneer species would be the grasses that first appear. Lichen would not be necessary as there is already nutrient-rich soil. Slowly, the field would return to its natural state. Q: What is the type of succession that happens after the destruction of a habitat? A:
****
A: secondary succession

Answer the following question given this paragraph: In most species, one or both parents take care of the eggs. They sit on the eggs to keep them warm until they hatch. This is called incubation. After the eggs hatch, the parents generally continue their care. They feed the hatchlings until they are big enough to feed on their own. This is usually at a younger age in ground-nesting birds such as ducks than in tree-nesting birds such as robins. Q: When animals use incubation, how do they generally give birth to their young? A:
OPTIONS:
- copying
- live
- division
- eggs
eggs

Answer the following question given this paragraph: When using the lens makers equation, remember that real things get positive numbers and virtual things get negative numbers. Thus, diverging lenses and virtual images get negative numbers. The object distance is always positive. Q: In the lens makers' equation, diverging lenses and virtual images are associated with what kinds of numbers? A:
OPTIONS:
- positive numbers
- variable numbers
- fractional numbers
- negative numbers

Answer: negative numbers

Question: Answer the following question given this paragraph: Advection fog is famous in San Francisco, California. Warm, moist air comes in from the Pacific Ocean. The air blows over the cold California current. When the air cools below its dew point, fog forms. Sea breezes bring the fog onshore. Q: What forms after air cools below its dew point? A:
OPTIONS:
- sleet
- smoke
- plasma
- fog
Answer: fog

input with options: Answer the following question given this paragraph: How metalloids behave in chemical interactions with other elements depends mainly on the number of electrons in the outer energy level of their atoms. Metalloids have from three to six electrons in their outer energy level. Boron, pictured in the Figure below , is the only metalloid with just three electrons in its outer energy level. It tends to act like metals by giving up its electrons in chemical reactions. Metalloids with more than four electrons in their outer energy level (arsenic, antimony, and tellurium) tend to act like nonmetals by gaining electrons in chemical reactions. Those with exactly four electrons in their outer energy level (silicon and germanium) may act like either metals or nonmetals, depending on the other elements in the reaction. Q: How metalloids behave in chemical interactions with other elements depends mainly on the number of what, in the outer energy level of their atoms? A:
OPTIONS:
- protons
- positrons
- neutrons
- electrons
output: electrons

Problem: OPTIONS:
- atmosphere
- ocean
- upper crust
- mantle
Q: Answer the following question given this paragraph: Convection in the mantle drives the movement of the plates of lithosphere over the Earth's surface. New oceanic crust forms at the ridge and pushes the older seafloor away from the ridge horizontally. Q: Convection in which part of the earth drives the movement of the plates of lithosphere over the earth's surface? A:
Answer:
mantle
