Problem: The earliest dynastic king on the Sumerian king list whose name is known from any other legendary source is Etana, 13th king of the first dynasty of Kish. The earliest king authenticated through archaeological evidence is Enmebaragesi of Kish (c. 26th century BC), whose name is also mentioned in the Gilgamesh epicleading to the suggestion that Gilgamesh himself might have been a historical king of Uruk. As the Epic of Gilgamesh shows, this period was associated with increased war. Cities became walled, and increased in size as undefended villages in southern Mesopotamia disappeared. (Gilgamesh is credited with having built the walls of Uruk).
Where is Enmebaragesi's name mentioned?

Answer: Gilgamesh epic

Problem: Another aspect of anti-aircraft defence was the use of barrage balloons to act as physical obstacle initially to bomber aircraft over cities and later for ground attack aircraft over the Normandy invasion fleets. The balloon, a simple blimp tethered to the ground, worked in two ways. Firstly, it and the steel cable were a danger to any aircraft that tried to fly among them. Secondly, to avoid the balloons, bombers had to fly at a higher altitude, which was more favorable for the guns. Barrage balloons were limited in application, and had minimal success at bringing down aircraft, being largely immobile and passive defences.
How was a barrage balloon tethered to the ground?

Answer: steel cable

Problem: Comcast was given an "F" for its corporate governance practices in 2010, by Corporate Library, an independent shareholder-research organization. According to Corporate Library, Comcast's board of directors ability to oversee and control management was severely compromised (at least in 2010) by the fact that several of the directors either worked for the company or had business ties to it (making them susceptible to management pressure), and a third of the directors were over 70 years of age. According to the Wall Street Journal nearly two-thirds of the flights of Comcast's $40 million corporate jet purchased for business travel related to the NBCU acquisition, were to CEO Brian Roberts' private homes or to resorts.
What company did Comcast give an F to?
