Pls help m What is the main difference between command and market economies?

A. In a command economy only, the government owns most of the businesses and means to make money.
B. In a market economy, the government decides the prices to make sure everyone has equal ability to pay for items; in a command economy, all items are provided.
C. A command economy is reflective of government regulation, while a market economy is reflective of what consumers want and need.
D. Competition only hurts the market economy as companies change prices and goods to meet consumer wants.

Can you summarize this? it takes time and caution to perfect anything which must be concealed. it takes time to crush men who are pursuing legitimate trade. but one of mr. rockefeller’s most impressive characteristics is patience. there never was a more patient man, or one who could dare more while he waited. the folly of hurrying, the folly of discouragement, for one who would succeed, went hand in hand. everything must be ready before he acted, but while you wait you must prepare, must think, work. "you must put in, if you would take out." his instinct for the money opportunity in things was amazing, his perception of the value of seizing this or that particular invention, plant, market, was unerring.
