Problem: The Battle of Stamford Bridge took place at the village of Stamford Bridge, East Riding of Yorkshire, in England on 25 September 1066, between an English army under King Harold Godwinson and an invading Norwegian force led by King Harald Hardrada and the English king's brother Tostig Godwinson. After a bloody battle, both Hardrada and Tostig along with most of the Norwegians were killed. Although Harold Godwinson repelled the Norwegian invaders, his army was defeated by the Normans at Hastings less than three weeks later. The battle has traditionally been presented as symbolising the end of the Viking Age, although major Scandinavian campaigns in Britain and Ireland occurred in the following decades, such as those of King Sweyn Estrithson of Denmark in 1069-1070 and King Magnus Barefoot of Norway in 1098 and 1102-1103.

Problem: The Colts began their season at Reliant Stadium in an AFC South duel against the Houston Texans.  Indianapolis started the season going 3-and-out on their first offensive possession of the new year.  The Texans got good field position with a big punt return from Jacoby Jones to set up a 30-yard field goal to give them a 3-0 lead. The offense continued to struggle throughout the first half, getting two first downs on the next drive, however, eventually having to punt.  The Texans continued to show energy on both offense and defense by scoring two more time, a field goal and a touchdown, giving the Texans a 13-0 lead halfway through the second quarter.  The Colts eventually got the offense going late in the second quarter by scoring on a touchdown reception by Reggie Wayne, which broke the lead down to one possession. Adam Vinatieri made a 20-yard field goal at the end of the first half and the Colts went into the half trailing 13-10. The momentum was seemingly shifting to Indianapolis, until Houston took almost eight minutes off the third quarter clock on a 15-play drive, 13 rushes, that resulted in one of Arian Foster's rushing touchdowns on the day to give Houston a 20-10 lead. Peyton Manning and the offense struggled throughout the third quarter with missed opportunities and continued to shoot themselves in the foot with penalties.  With the start of the fourth quarter Houston scored another touchdown and broke the game open.  The Colts would eventually score two touchdowns late in the game, only when there was no chance of a comeback. With the final score 34-24, the Colts were 0-1 to start a season for the first time since 2008, when they lost to the Chicago Bears.

Problem: The episode demonstrated to both Scotland and England the fruitlessness of their struggles. Thereafter, with France's fortunes falling and England's rising, the terms came to seem more favourable to the Scots, and in 1357 they were accepted after all, formalized in the Treaty of Berwick, under the terms of which Scotland would pay England 100,000 merks over a ten-year period. With the signing of the Treaty of Berwick, the Second War of Scottish Independence was effectively over. Even before the signing of the treaty, in January 1356, Edward Balliol — weary and ill — had relinquished his claim in the kingdom of Scotland to Edward III in exchange for an annuity of £2000. He retired to live the rest of his life in the area of Yorkshire. David II returned to Scotland, to try again to deal with the rivalries of his lords as well as now among his ladies, as his wife Joan evidently objected to the English mistress he had taken during his 11 years in captivity. The treaty did impose a financial hardship on Scotland, but David II stopped paying after only 20,000 merks of the debt had been met, following which renegotiation led ultimately to a reduction in the debt and a 14-year truce.
