Problem: The Lines of Communication were English Civil War fortifications commissioned by Parliament  and built around London between 1642 and 1643 to protect the capital from attack by the Royalist armies of Charles I. In 1642 some basic fortifications were built, in the form of street barricades and small earthworks. In 1643 a major construction effort was made, to provide a comprehensive ring of fortifications around the city. Much of the work was done by volunteer labour, organized by the trained bands and the livery companies. Up to 20,000 people are thought to be involved, and the works were completed in under two months. The fortifications failed their only test when the New Model Army entered London in 1647, and they were levelled by Parliament the same year.
Answer this question based on the article: How many years after major fortifications were build around the city, were they levelled by Parliament?
A: 4

Problem: Hoping to rebound from their home loss to the Bears, the Colts flew to the Hubert H. Humphrey Metrodome for a Week 2 interconference duel with the Minnesota Vikings.  In the first half, Indianapolis trailed as Vikings kicker Ryan Longwell got a 45-yard and a 27-yard field goal in the first quarter, along with a 53-yard field goal in the second quarter.  It marked the first time that the Colts got shut out in the first half since October 2006. In the third quarter, Minnesota increased its lead with Longwell nailing a 46-yard and a 28-yard field goal.  Afterwards, Indianapolis started to rally as RB Joseph Addai got a 1-yard TD run.  In the fourth quarter, the Colts drew closer as QB Peyton Manning completed a 32-yard TD pass to WR Reggie Wayne, followed by a 2-point conversion run by RB Dominic Rhodes.  Afterwards, near the end of game, Indianapolis completed its comeback as kicker Adam Vinatieri nailing the game-winning 47-yard field goal.

Problem: In February 1916 the Germans attacked French defensive positions at the Battle of Verdun, lasting until December 1916. The Germans made initial gains, before French counter-attacks returned matters to near their starting point. Casualties were greater for the French, but the Germans bled heavily as well, with anywhere from 700,000 to 975,000 casualties suffered between the two combatants. Verdun became a symbol of French determination and self-sacrifice. The Battle of the Somme was an Anglo-French offensive of July to November 1916. The opening day of the offensive  was the bloodiest day in the history of the British Army, suffering 57,470 casualties, including 19,240 dead. The entire Somme offensive cost the British Army some 420,000 casualties. The French suffered another estimated 200,000 casualties and the Germans an estimated 500,000. Gun fire wasn't the only factor taking lives; the diseases that emerged in the trenches were a major killer on both sides. The living conditions made it so that countless diseases and infections occurred, such as trench foot, shell shock, blindness/burns from mustard gas, lice, trench fever, cooties  and the ‘Spanish Flu'.
