Question: Cordwood construction can save significant space and was often used with wire-ended components in applications where space was at a premium (such as missile guidance and telemetry systems) and in high-speed computers, where short traces were important. In cordwood construction, axial-leaded components were mounted between two parallel planes. The components were either soldered together with jumper wire, or they were connected to other components by thin nickel ribbon welded at right angles onto the component leads. To avoid shorting together different interconnection layers, thin insulating cards were placed between them. Perforations or holes in the cards allowed component leads to project through to the next interconnection layer. One disadvantage of this system was that special nickel-leaded components had to be used to allow the interconnecting welds to be made. Differential thermal expansion of the component could put pressure on the leads of the components and the PCB traces and cause physical damage (as was seen in several modules on the Apollo program). Additionally, components located in the interior are difficult to replace. Some versions of cordwood construction used soldered single-sided PCBs as the interconnection method (as pictured), allowing the use of normal-leaded components.
Is there an answer to this question: What does not save significant space?

Answer: unanswerable


Question: In the Ottoman Empire, these ideological reforms did not take place and these views did not integrate into common thought until much later. As well, there was no spread of this doctrine within the New World and the advanced civilizations of the Aztec, Maya, Inca, Mohican, Delaware, Huron and especially the Iroquois. The Iroquois philosophy in particular gave much to Christian thought of the time and in many cases actually inspired some of the institutions adopted in the United States: for example, Benjamin Franklin was a great admirer of some of the methods of the Iroquois Confederacy, and much of early American literature emphasized the political philosophy of the natives.
Is there an answer to this question: Who was a great admirer of some of the methods of the Iroquois Confederacy?

Answer: Benjamin Franklin


Question: Elizabeth's personal fortune has been the subject of speculation for many years. Jock Colville, who was her former private secretary and a director of her bank, Coutts, estimated her wealth in 1971 at £2 million (equivalent to about £25 million today). In 1993, Buckingham Palace called estimates of £100 million "grossly overstated". She inherited an estimated £70 million estate from her mother in 2002. The Sunday Times Rich List 2015 estimated her private wealth at £340 million, making her the 302nd richest person in the UK.
Is there an answer to this question: In what year did Jock Colville become Elizabeth's private secretary?

Answer: unanswerable


Question: The transition from hunting and gathering to agriculture is not necessarily a one way process. It has been argued that hunting and gathering represents an adaptive strategy, which may still be exploited, if necessary, when environmental change causes extreme food stress for agriculturalists. In fact, it is sometimes difficult to draw a clear line between agricultural and hunter-gatherer societies, especially since the widespread adoption of agriculture and resulting cultural diffusion that has occurred in the last 10,000 years.[citation needed] This anthropological view has remained unchanged since the 1960s.[clarification needed][citation needed]
Is there an answer to this question: Besides the use of agriculture, what other factor clouds the issue of the transition from hunting and gathering to agriculture?

Answer:
cultural diffusion
