Problem: OPTIONS:
- it warms
- it cracks
- it sinks
- it melts
Q: Answer the following question given this paragraph: Composite volcanoes are common along convergent plate boundaries. When a tectonic plate subducts, it melts. This creates the thick magma needed for these eruptions. The Pacific Ring of Fire is dotted by composite volcanoes. Q: What happens to a tectonic plate when it subducts? A:
Answer: it melts

Problem:OPTIONS:
- radiation field
- molecular field
- gravitational field
- magnetic field

Answer the following question given this paragraph: An electromagnetic wave consists of vibrating electric and magnetic fields. Q: In addition to a vibrating electric field what does an electromagnetic wave consist of? A:
****
A: magnetic field

Answer the following question given this paragraph: If the rocks on one or both sides of a fracture move, the fracture is called a fault ( Figure below ). Faults can occur alone or in clusters. A cluster of faults creates a fault zone . Earthquakes happen when rocks break and move suddenly. The energy released causes an earthquake. Q: What is the fracture called when rocks on both sides move? A:
OPTIONS:
- a crevice
- a shear
- a stress fracture
- a fault
a fault

Answer the following question given this paragraph: The transition metals are an interesting and challenging group of elements. They have perplexing patterns of electron distribution that don't always follow the electron filling rules. Predicting how they will form ions is also not always obvious. Q: What kind of metals have perplexing patterns of electron distribution that don't always follow the electron filling rules? A:
OPTIONS:
- solution
- transformation
- variating
- transition

Answer: transition

Question: Answer the following question given this paragraph: Mammals are a class of endothermic vertebrates. They have four limbs and produce amniotic eggs. Examples of mammals include bats, whales, mice, and humans. Clearly, mammals are a very diverse group. Nonetheless, they share many traits that set them apart from other vertebrates. Q: Mammals belong to which class of vertebrates? A:
OPTIONS:
- agnathas
- chondrichthyes
- placoderms
- endothermic
Answer: endothermic

input: OPTIONS:
- polarity
- heat
- precipitation
- density Now, answer this question: Answer the following question given this paragraph: After trees are cut, logging companies often move these materials down a river to a sawmill where they can be shaped into building materials or other products. The logs float on the water because they are less dense than the water they are in. Knowledge of density is important in the characterization and separation of materials. Information about density allows us to make predictions about the behavior of matter. Q: What property allows cut logs to float on water? A:
A:
output:
density
