Question: Answer the following question given this paragraph: Hair Growth Hair grows and is eventually shed and replaced by new hair. This occurs in three phases. The first is the anagen phase, during which cells divide rapidly at the root of the hair, pushing the hair shaft up and out. The length of this phase is measured in years, typically from 2 to 7 years. The catagen phase lasts only 2 to 3 weeks, and marks a transition from the hair follicle's active growth. Finally, during the telogen phase, the hair follicle is at rest and no new growth occurs. At the end of this phase, which lasts about 2 to 4 months, another anagen phase begins. The basal cells in the hair matrix then produce a new hair follicle, which pushes the old hair out as the growth cycle repeats itself. Hair typically grows at the rate of 0.3 mm per day during the anagen phase. On average, 50 hairs are lost and replaced per day. Hair loss occurs if there is more hair shed than what is replaced and can happen due to hormonal or dietary changes. Hair loss can also result from the aging process, or the influence of hormones. Q: Anagen, catagen and telogen are phases in the growth of what, which involves the root and follicle? Choices: - brain - teeth - bone - hair A:
Answer: hair

Answer the following question given this paragraph: Do you see the man sitting on top of this tanker truck? He gives you a sense of how big the truck is. What's behind the truck? Is it a huge apartment complex? It's just as massive as a very large building, but it's not even resting on land. It's a giant cruise ship, and it's floating on water. The ship weighs about 100,000 metric tons. How can such a tremendous weight float on water? Why doesn't it sink to the bottom of the ocean instead? Archimedes' law explains why. Q: Which law explains why a ship weighing thousands of metric tons floats on water? Choices: - hofstadter ' law - ganymede ' law - water pressure law - archimedes' law A:
(A).
archimedes' law
