Question: Answer the following question given this paragraph: When compounds are synthesized, they often have contaminating materials mixed in with them. The process of recrystallization can be used to remove these impurities. The crystals are dissolved in a hot solvent, forming a solution. When the solvent is cooled the compound is no longer as soluble and will precipitate out of solution, leaving other materials still dissolved. Q: Recrystallization is a process that can remove what, which result when compounds are synthesized? A:
OPTIONS:
- chemicals
- substances
- minerals
- contaminants
Answer: contaminants

input with options: Answer the following question given this paragraph: The red blood cells of a person with sickle-cell anemia (left) are long and pointed, rather than straight, like normal cells (right). The abnormal cells cannot carry oxygen properly and can get stuck in capillaries. Q: The abnormal cells cannot carry oxygen properly and can get stuck where? A:
OPTIONS:
- muscles
- Viens
- Arteries
- capillaries
output: capillaries

Q: Answer the following question given this paragraph: Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes. Q: Which process is glycolysis in during cellular respiration? A:

OPTIONS:
- aerobic
- hydrolysis
- enzymatic
- anaerobic

A: anaerobic

input: OPTIONS:
- fermentation
- global warming
- combustion
- condensation Now, answer this question: Answer the following question given this paragraph: Condensation changes water vapor to liquid water. As air rises higher into the atmosphere, it cools. Cool air can hold less water vapor than warm air. So some of the water vapor condenses into water droplets. Water droplets may form clouds. Q: What changes water vapor to liquid water? A:
A:
output: condensation

Answer the following question given this paragraph: Arteries are muscular blood vessels that carry blood away from the heart. They have thick walls that can withstand the pressure of blood being pumped by the heart. Arteries generally carry oxygen-rich blood. The largest artery is the aorta, which receives blood directly from the heart. Q: What type of blood vessels carry blood away from the heart? A:

OPTIONS:
- Heart
- tubes
- Viens
- arteries

Answer: arteries

Q: Answer the following question given this paragraph: Arthropods have a life cycle with sexual reproduction. Most species go through larval stages after hatching. The larvae are very different from the adults. They change into the adult form in a process called metamorphosis . This may take place within a cocoon. A familiar example of metamorphosis is the transformation of a caterpillar (larva) into a butterfly (adult). Other arthropod species, in contrast, hatch young that look like small adults. These species lack both larval stages and metamorphosis. Q: Arthropods change into the adult form in a process called what? A:

OPTIONS:
- parthenogenesis
- spontaneous mutation
- budding
- metamorphosis

A:
metamorphosis
