Q: World War I began as a clash of 20th-century technology and 19th-century tactics, with the inevitably large ensuing casualties. By the end of 1917, however, the major armies, now numbering millions of men, had modernised and were making use of telephone, wireless communication, armoured cars, tanks, and aircraft. Infantry formations were reorganised, so that 100-man companies were no longer the main unit of manoeuvre; instead, squads of 10 or so men, under the command of a junior NCO, were favoured. Artillery also underwent a revolution. In 1914, cannons were positioned in the front line and fired directly at their targets. By 1917, indirect fire with guns  was commonplace, using new techniques for spotting and ranging, notably aircraft and the often overlooked field telephone. Counter-battery missions became commonplace, also, and sound detection was used to locate enemy batteries.
How many years passed from the revolution in 1914 to when indirect fire with guns became commonplace?

A: 3


Q: The Bucs' playoff hopes took hits after a second loss in a row, this time to the New Orleans Saints. Their defense was shaky, as they allowed 13 points in the first half of the game, and 18 points in the second half. This put the Bucs outside the playoff picture, and left them requiring victory in week 17 as well as hoping for the Washington Redskins and the Green Bay Packers to both lose. Mark Ingram scored two touchdowns, during the game, and Jameis Winston was picked off twice during the game, unlike the previous meeting of the two teams a couple weeks ago.
Who threw two interceptions?

A: Jameis Winston
