input: OPTIONS:
- density
- permeability
- vibration
- reactivity Now, answer this question: Answer the following question given this paragraph: Some nonmetals are very reactive, whereas others are not reactive at all. It depends on the number of electrons in their outer energy level. Q: The number of electrons in the outer energy level determines what property of nonmetals? A:
A:
output: reactivity

input: OPTIONS:
- viruses
- multicellular bacteria
- acids
- fungi Now, answer this question: Answer the following question given this paragraph: Several common human diseases are caused by fungi.

Athlete's foot is the second most common skin disease in the U. S. Q: Ringworm and athlete's foot are common human diseases caused by types of what? A:
A:
output: fungi

input: OPTIONS:
- hill
- groundwater
- mountain
- sinkhole Now, answer this question: Answer the following question given this paragraph: As erosion by groundwater continues, the ceiling of a cave may collapse. The rock and soil above it sink into the ground. This forms a sinkhole on the surface. You can see an example of a sinkhole in Figure below . Some sinkholes are big enough to swallow vehicles and buildings. Q: What is formed when the ceiling of an underground cave collapses? A:
A:
output:
sinkhole
