The Austrian engineer Paul Eisler invented the printed circuit as part of a radio set while working in England around 1936. Around 1943 the USA began to use the technology on a large scale to make proximity fuses for use in World War II. After the war, in 1948, the USA released the invention for commercial use. Printed circuits did not become commonplace in consumer electronics until the mid-1950s, after the Auto-Sembly process was developed by the United States Army. At around the same time in Britain work along similar lines was carried out by Geoffrey Dummer, then at the RRDE.
What event prompted the United States to adopt the printed circuit to make proximity fuses?
World War II

Input: Article: During the Pacific War Funafuti was used as a base to prepare for the subsequent seaborn attacks on the Gilbert Islands (Kiribati) that were occupied by Japanese forces. The United States Marine Corps landed on Funafuti on 2 October 1942 and on Nanumea and Nukufetau in August 1943. The Japanese had already occupied Tarawa and other islands in what is now Kiribati, but were delayed by the losses at the Battle of the Coral Sea. The islanders assisted the American forces to build airfields on Funafuti, Nanumea and Nukufetau and to unload supplies from ships. On Funafuti the islanders shifted to the smaller islets so as to allow the American forces to build the airfield and to build naval bases and port facilities on Fongafale. A Naval Construction Battalion (Seabees) built a sea plane ramp on the lagoon side of Fongafale islet for seaplane operations by both short and long range seaplanes and a compacted coral runway was also constructed on Fongafale, with runways also constructed to create Nanumea Airfield and Nukufetau Airfield. USN Patrol Torpedo Boats (PTs) were based at Funafuti from 2 November 1942 to 11 May 1944.

Now answer this question: For what purpose was Funafuti used during the Pacific War? 

Output: a base


Article: Imperial's main campus is located in the South Kensington area of central London. It is situated in an area of South Kensington, known as Albertopolis, which has a high concentration of cultural and academic institutions, adjacent to the Natural History Museum, the Science Museum, the Victoria and Albert Museum, the Royal College of Music, the Royal College of Art, the Royal Geographical Society and the Royal Albert Hall. Nearby public attractions include the Kensington Palace, Hyde Park and the Kensington Gardens, the National Art Library, and the Brompton Oratory. The expansion of the South Kensington campus in the 1950s & 1960s absorbed the site of the former Imperial Institute, designed by Thomas Collcutt, of which only the 287 foot (87 m) high Queen's Tower remains among the more modern buildings.

Question: Which landmark still remains from the Imperial Institue after Imperial's expansion?

Here is a question about this article: The polyphony of Christian a cappella music began to develop in Europe around the late 15th century, with compositions by Josquin des Prez. The early a cappella polyphonies may have had an accompanying instrument, although this instrument would merely double the singers' parts and was not independent. By the 16th century, a cappella polyphony had further developed, but gradually, the cantata began to take the place of a cappella forms. 16th century a cappella polyphony, nonetheless, continued to influence church composers throughout this period and to the present day. Recent evidence has shown that some of the early pieces by Palestrina, such as what was written for the Sistine Chapel was intended to be accompanied by an organ "doubling" some or all of the voices. Such is seen in the life of Palestrina becoming a major influence on Bach, most notably in the aforementioned Mass in B Minor. Other composers that utilized the a cappella style, if only for the occasional piece, were Claudio Monteverdi and his masterpiece, Lagrime d'amante al sepolcro dell'amata (A lover's tears at his beloved's grave), which was composed in 1610, and Andrea Gabrieli when upon his death it was discovered many choral pieces, one of which was in the unaccompanied style. Learning from the preceding two composeres, Heinrich Schütz utilized the a cappella style in numerous pieces, chief among these were the pieces in the oratorio style, which were traditionally performed during the Easter week and dealt with the religious subject matter of that week, such as Christ's suffering and the Passion. Five of Schutz's Historien were Easter pieces, and of these the latter three, which dealt with the passion from three different viewpoints, those of Matthew, Luke and John, were all done a cappella style. This was a near requirement for this type of piece, and the parts of the crowd were sung while the solo parts which were the quoted parts from either Christ or the authors were performed in a plainchant.
What is the answer to this question: Who was a known composer of A cappella music in the 15th century?
****
So... Josquin des Prez
