input: OPTIONS:
- inhibited hormone
- tharayroid hormone
- elevated hormone
- parathyroid hormone Now, answer this question: Answer the following question given this paragraph: Hyperparathyroidism results from an overproduction of parathyroid hormone. This results in excessive calcium being removed from bones and introduced into blood circulation, producing structural weakness of the bones, which can lead to deformation and fractures, plus nervous system impairment due to high blood calcium levels. Hypoparathyroidism, the underproduction of PTH, results in extremely low levels of blood calcium, which causes impaired muscle function and may result in tetany (severe sustained muscle contraction). The hormone calcitonin, which is produced by the parafollicular or C cells of the thyroid, has the opposite effect on blood calcium levels as does PTH. Calcitonin decreases blood calcium levels by inhibiting osteoclasts, stimulating osteoblasts, and stimulating calcium excretion by the kidneys. This results in calcium being added to the bones to promote structural integrity. Calcitonin is most important in children (when it stimulates bone growth), during pregnancy (when it reduces maternal bone loss), and during prolonged starvation (because it reduces bone mass loss). In healthy nonpregnant, unstarved adults, the role of calcitonin is unclear. Q: Hyperparathyroidism results from an overproduction of what? A:
A:
output: parathyroid hormone

Answer the following question given this paragraph: Solutions may be prepared in which a solute concentration exceeds its solubility. Such solutions are said to be supersaturated, and they are interesting examples of nonequilibrium states. For example, the carbonated beverage in an open container that has not yet "gone flat" is supersaturated with carbon dioxide gas; given time, the CO2 concentration will decrease until it reaches its equilibrium value. Q: Solutions that are prepared in which a solute concentration exceeds its solubility are called what? A:

OPTIONS:
- solidified
- instantiated
- mineralized
- supersaturated

Answer: supersaturated

Q: What strong and lightweight manmade material is derived from hydrocarbons and used in ropes, tents and parachutes? A:

OPTIONS:
- styrofoam
