Here is a question about this article: Several systems were proposed as the new standard for the US, including the Japanese MUSE system, but all were rejected by the FCC because of their higher bandwidth requirements. At this time, the number of television channels was growing rapidly and bandwidth was already a problem. A new standard had to be more efficient, needing less bandwidth for HDTV than the existing NTSC.
What is the answer to this question: What was the existing system at the time?
****
So... NTSC

Here is a question about this article: He was a pioneer of the application of operator theory to quantum mechanics, in the development of functional analysis, a principal member of the Manhattan Project and the Institute for Advanced Study in Princeton (as one of the few originally appointed), and a key figure in the development of game theory and the concepts of cellular automata, the universal constructor and the digital computer. He published 150 papers in his life; 60 in pure mathematics, 20 in physics, and 60 in applied mathematics. His last work, an unfinished manuscript written while in the hospital, was later published in book form as The Computer and the Brain.
What is the answer to this question: What is the name of Von Neumann's last work?

So... The Computer and the Brain

Here is a question about this article: Spanish explorers traveling inland in the 16th century met Mississippian culture people at Joara, a regional chiefdom near present-day Morganton. Records of Hernando de Soto attested to his meeting with them in 1540. In 1567 Captain Juan Pardo led an expedition to claim the area for the Spanish colony and to establish another route to protect silver mines in Mexico. Pardo made a winter base at Joara, which he renamed Cuenca. His expedition built Fort San Juan and left a contingent of 30 men there, while Pardo traveled further, and built and garrisoned five other forts. He returned by a different route to Santa Elena on Parris Island, South Carolina, then a center of Spanish Florida. In the spring of 1568, natives killed all but one of the soldiers and burned the six forts in the interior, including the one at Fort San Juan. Although the Spanish never returned to the interior, this effort marked the first European attempt at colonization of the interior of what became the United States. A 16th-century journal by Pardo's scribe Bandera and archaeological findings since 1986 at Joara have confirmed the settlement.
What is the answer to this question: What is Joara?

So...
a regional chiefdom
