Problem: Renewable energy commercialization:

Some countries are eliminating or reducing climate disrupting subsidies and Belgium, France, and Japan have phased out all subsidies for coal. Germany is reducing its coal subsidy. The subsidy dropped from $5.4 billion in 1989 to $2.8 billion in 2002, and in the process Germany lowered its coal use by 46 percent. China cut its coal subsidy from $750 million in 1993 to $240 million in 1995 and more recently has imposed a high-sulfur coal tax. However, the United States has been increasing its support for the fossil fuel and nuclear industries.

Problem: Time:

The most precise timekeeping device of the ancient world was the water clock, or clepsydra, one of which was found in the tomb of Egyptian pharaoh Amenhotep I (15251504 BC). They could be used to measure the hours even at night, but required manual upkeep to replenish the flow of water. The Ancient Greeks and the people from Chaldea (southeastern Mesopotamia) regularly maintained timekeeping records as an essential part of their astronomical observations. Arab inventors and engineers in particular made improvements on the use of water clocks up to the Middle Ages. In the 11th century, Chinese inventors and engineers invented the first mechanical clocks driven by an escapement mechanism.

What device was invented by the ancient Greeks?

A: unanswerable

Problem: Egypt:

In 1975, Sadat shifted Nasser's economic policies and sought to use his popularity to reduce government regulations and encourage foreign investment through his program of Infitah. Through this policy, incentives such as reduced taxes and import tariffs attracted some investors, but investments were mainly directed at low risk and profitable ventures like tourism and construction, abandoning Egypt's infant industries. Even though Sadat's policy was intended to modernise Egypt and assist the middle class, it mainly benefited the higher class, and, because of the elimination of subsidies on basic foodstuffs, led to the 1977 Egyptian Bread Riots.

What was encouraged through Infitah?
---
A: foreign investment
