Problem: Please answer a question about the following article about Qing dynasty:
The government broadened land ownership by returning land that had been sold to large landowners in the late Ming period by families unable to pay the land tax. To give people more incentives to participate in the market, they reduced the tax burden in comparison with the late Ming, and replaced the corvee system with a head tax used to hire laborers. The administration of the Grand Canal was made more efficient, and transport opened to private merchants. A system of monitoring grain prices eliminated severe shortages, and enabled the price of rice to rise slowly and smoothly through the 18th century. Wary of the power of wealthy merchants, Qing rulers limited their trading licenses and usually refused them permission to open new mines, except in poor areas. These restrictions on domestic resource exploration, as well as on foreign trade, are held by some scholars as a cause of the Great Divergence, by which the Western world overtook China economically.
What did the Qing do to reform land ownership?
A: reduced the tax burden
Problem: Please answer a question about the following article about John von Neumann:
along with two inequality systems expressing economic efficiency. In this model, the (transposed) probability vector p represents the prices of the goods while the probability vector q represents the "intensity" at which the production process would run. The unique solution represents the growth factor which is 1 plus the rate of growth of the economy; the rate of growth equals the interest rate. Proving the existence of a positive growth rate and proving that the growth rate equals the interest rate were remarkable achievements, even for von Neumann.
In von Neumann's model what does q represent?
A: q represents the "intensity" at which the production process would run
Problem: Please answer a question about the following article about Arena Football League:
For its 2015 season, the league consisted of 12 teams, all from the United States; however, upon the completion of the regular season, the league announced that the two teams it had assumed operation of during the season would cease all operations effective immediately; a regular season game slated between the two had previously been canceled and declared a tie.
