Question: Through-hole manufacture adds to board cost by requiring many holes to be drilled accurately, and limits the available routing area for signal traces on layers immediately below the top layer on multi-layer boards since the holes must pass through all layers to the opposite side. Once surface-mounting came into use, small-sized SMD components were used where possible, with through-hole mounting only of components unsuitably large for surface-mounting due to power requirements or mechanical limitations, or subject to mechanical stress which might damage the PCB.
Try to answer this question if possible: What increases the available routing area?
Answer: unanswerable
Question: Prior to the Golden Age of Mandolins, France had a history with the mandolin, with mandolinists playing in Paris until the Napoleonic Wars. The players, teachers and composers included Giovanni Fouchetti, Eduardo Mezzacapo, Gabriele Leon, and Gervasio. During the Golden age itself (1880s-1920s), the mandolin had a strong presence in France. Prominent mandolin players or composers included Jules Cottin and his sister Madeleine Cottin, Jean Pietrapertosa, and Edgar Bara. Paris had dozens of "estudiantina" mandolin orchestras in the early 1900s. Mandolin magazines included L'Estudiantina, Le Plectre, École de la mandolie.
Try to answer this question if possible:  What years weren't considered the Golden Age of Mandolins?
Answer: unanswerable
Question: In March's Super Tuesday, Kerry won decisive victories in the California, Connecticut, Georgia, Maryland, Massachusetts, New York, Ohio, and Rhode Island primaries and the Minnesota caucuses. Dean, despite having withdrawn from the race two weeks earlier, won his home state of Vermont. Edwards finished only slightly behind Kerry in Georgia, but, failing to win a single state other than South Carolina, chose to withdraw from the presidential race. Sharpton followed suit a couple weeks later. Kuninch did not leave the race officially until July.
Try to answer this question if possible: When did Kuninch win victories in California, Connecticut and Georgia?
Answer: unanswerable
Question: Midway through the 19th century, the focus of geology shifted from description and classification to attempts to understand how the surface of the Earth had changed. The first comprehensive theories of mountain building were proposed during this period, as were the first modern theories of earthquakes and volcanoes. Louis Agassiz and others established the reality of continent-covering ice ages, and "fluvialists" like Andrew Crombie Ramsay argued that river valleys were formed, over millions of years by the rivers that flow through them. After the discovery of radioactivity, radiometric dating methods were developed, starting in the 20th century. Alfred Wegener's theory of "continental drift" was widely dismissed when he proposed it in the 1910s, but new data gathered in the 1950s and 1960s led to the theory of plate tectonics, which provided a plausible mechanism for it. Plate tectonics also provided a unified explanation for a wide range of seemingly unrelated geological phenomena. Since 1970 it has served as the unifying principle in geology.
Try to answer this question if possible: The idea of an ice-age that completely covered a continent was suggested by whom?
Answer:
Louis Agassiz
