Answer the following question given this paragraph: A snowflake is made of ice, or water in the solid state. A solid is one of four well-known states of matter. The other three states are liquid, gas, and plasma. Compared with these other states of matter, solids have particles that are much more tightly packed together. The particles are held rigidly in place by all the other particles around them so they can't slip past one another or move apart. This gives solids a fixed shape and a fixed volume. Q: What state of matter completes the list: solid, liquid, gas? Choices: - energy - ice - power - plasma A:
plasma
Answer the following question given this paragraph: Mercury is the smallest planet and the closest to the Sun. It has an extremely thin atmosphere so surface temperatures range from very hot to very cold. Like the Moon, it is covered with craters. Q: What is the smallest planet in our solar system? Choices: - Earth - Jupiter - Mars - mercury A:
mercury
Q: Answer the following question given this paragraph: Chemical reactions constantly occur inside the cells of living things. However, under the conditions inside cells, most biochemical reactions would occur too slowly to maintain life. That's where enzymes come in. Enzymes are catalysts in living things. Like other catalysts, they speed up chemical reactions. Enzymes are proteins that are synthesized in the cells that need them, based on instructions encoded in the cells' DNA. Q: What proteins synthesized in cells act as catalysts? Choices: - hormones - virophages - byproducts - enzymes A:
A: enzymes
Question: Answer the following question given this paragraph: Earthquakes also occur at divergent plate boundaries. At mid-ocean ridges, these earthquakes tend to be small and shallow focus because the plates are thin, young, and hot. Earthquakes in the oceans are usually far from land, so they have little effect on peoples' lives. On land, where continents are rifting apart, earthquakes are larger and stronger. Q: What causes earthquakes at mid-ocean ridges to be small and shallow? Choices: - plates are thin , young , and cold - plates are thick , young , and cold - plates are thick , old , and hot - plates are thin , young , and hot A:
Answer: plates are thin , young , and hot

Answer the following question given this paragraph: Most substances may exist in any of the three common states of matter. In the gaseous state, the molecular motion has completely overcome any attraction between the particles and the particles are totally separate from each other. There are large spaces between the particles and they move large distances between collisions. In the liquid state, the molecular motion and the molecular attractions are more balanced. While the particles stay more or less in contact with each other, they are still free to move and can slide past one another easily. In the solid state, the attractive forces dominate. The particles are pulled together into a tightly packed pattern which does not allow the particles to pass each other. The molecular motion in this form is essentially reduced to vibration in place. Increasing the temperature of a substance means increasing the molecular motion (kinetic energy) of the molecules in the substance. The phase in which a substance exists is the result of a competition between attractive forces and molecular motion. Q: In which state of matter are particles completely separate from one another? Choices: - phosphorus state - solid state - liquid state - gaseous state A:
**Answer**
gaseous state
Answer the following question given this paragraph: Sexual reproduction is typically slower. However, it also has an advantage. Sexual reproduction results in offspring that are all genetically different. This can be a big plus for a species. The variation may help it adapt to changes in the environment. Q: What kind of reproduction results in offspring that are generally all genetically different? Choices: - perceptual - asexual - individual - sexual A:
sexual
