Problem: While the times of sunrise and sunset change at roughly equal rates as the seasons change, proponents of Daylight Saving Time argue that most people prefer a greater increase in daylight hours after the typical "nine-to-five" workday. Supporters have also argued that DST decreases energy consumption by reducing the need for lighting and heating, but the actual effect on overall energy use is heavily disputed.
What two sources of energy use do DST proponents say are reduced by the time change?

Answer: lighting and heating

Problem: As of 2009, Internet via satellite had a steady growth rate of 10% to 15% per year. It was particularly in demand in remote areas that did not have either dialup or wireless online services. The local telecommunications company Dalkom Somalia provided internet over satellite, as well as premium routes for media operators and content providers, and international voice gateway services for global carriers. It also offered inexpensive bandwidth through its internet backbone, whereas bandwidth ordinarily cost customers from $2,500 to $3,000 per month through the major international bandwidth providers. The main clients of these local satellite services were internet cafes, money transfer firms and other companies, as well as international community representatives. In total, there were over 300 local satellite terminals available aross the nation, which were linked to teleports in Europe and Asia. Demand for the satellite services gradually began to fall as broadband wireless access rose. However, it increased in rural areas, as the main client base for the satellite services extended their operations into more remote locales.
Who provided broadband wireless access?

Problem: In 586 BCE King Nebuchadnezzar II of Babylon conquered Judah. According to the Hebrew Bible, he destroyed Solomon's Temple and exiled the Jews to Babylon. The defeat was also recorded by the Babylonians (see the Babylonian Chronicles). In 538 BCE, Cyrus the Great of Persia conquered Babylon and took over its empire. Cyrus issued a proclamation granting subjugated nations (including the people of Judah) religious freedom (for the original text, which corroborates the biblical narrative only in very broad terms, see the Cyrus Cylinder). According to the Hebrew Bible 50,000 Judeans, led by Zerubabel, returned to Judah and rebuilt the temple. A second group of 5,000, led by Ezra and Nehemiah, returned to Judah in 456 BCE although non-Jews wrote to Cyrus to try to prevent their return.
How many Judeans did Zerubabel return to Judah?
