Question: Surface-mount technology emerged in the 1960s, gained momentum in the early 1980s and became widely used by the mid-1990s. Components were mechanically redesigned to have small metal tabs or end caps that could be soldered directly onto the PCB surface, instead of wire leads to pass through holes. Components became much smaller and component placement on both sides of the board became more common than with through-hole mounting, allowing much smaller PCB assemblies with much higher circuit densities. Surface mounting lends itself well to a high degree of automation, reducing labor costs and greatly increasing production rates. Components can be supplied mounted on carrier tapes. Surface mount components can be about one-quarter to one-tenth of the size and weight of through-hole components, and passive components much cheaper; prices of semiconductor surface mount devices (SMDs) are determined more by the chip itself than the package, with little price advantage over larger packages. Some wire-ended components, such as 1N4148 small-signal switch diodes, are actually significantly cheaper than SMD equivalents.
Is there an answer to this question: What did the new components with end tabs replace?

Answer: wire leads


Question: In spring 1855, the allied British-French commanders decided to send an Anglo-French naval squadron into the Azov Sea to undermine Russian communications and supplies to besieged Sevastopol. On 12 May 1855, British-French warships entered the Kerch Strait and destroyed the coast battery of the Kamishevaya Bay. On 21 May 1855, the gunboats and armed steamers attacked the seaport of Taganrog, the most important hub near Rostov on Don. The vast amounts of food, especially bread, wheat, barley, and rye that were amassed in the city after the outbreak of war were prevented from being exported.
Is there an answer to this question: What did the British-French commanders send to disrupt Russian communications and supplies?

Answer: Anglo-French naval squadron


Question: The WVS (Women's Voluntary Services for Civil Defence) was set up under the direction of Samuel Hoare, Home Secretary in 1938 specifically in the event of air raids. Hoare considered it the female branch of the ARP. They organised the evacuation of children, established centres for those displaced by bombing, and operated canteens, salvage and recycling schemes. By the end of 1941, the WVS had one million members. Prior to the outbreak of war, civilians were issued with 50 million respirators (gas masks). These were issued in the event of bombing taking place with gas before evacuation.
Is there an answer to this question: Who was Home Secretary in 1938?

Answer: Samuel Hoare


Question: An unconventional power succession system was established (rota system) whereby power was transferred to the eldest member of the ruling dynasty rather than from father to son, i.e. in most cases to the eldest brother of the ruler, fomenting constant hatred and rivalry within the royal family.[citation needed] Familicide was frequently deployed in obtaining power and can be traced particularly during the time of the Yaroslavichi rule (sons of Yaroslav) when the established system was skipped in the establishment of Vladimir II Monomakh as the Grand Prince of Kiev,[clarification needed] in turn creating major squabbles between Olegovichi from Chernihiv, Monomakhs from Pereyaslav, Izyaslavichi from Turov/Volhynia, and Polotsk Princes.[citation needed]
Is there an answer to this question: Who developed familicide?

Answer:
unanswerable
