Problem: In 1714, Peter the Great sent a party of shipbuilders to Okhotsk to allow faster access to the furs of Kamchatka. In 1715, they built the Vostok and in 1716–17 Kozma Sokolov sailed it to Kamchatka. For the next 145 years Okhotsk was the main Russian seaport on the Pacific, supplying Kamchatka and other coastal settlements. In 1731 the Siberian Military Flotilla was established here. In 1736, Okhotsk was moved two miles downstream to a spit of land at the mouth of the Okhota, converting the ostrog (fortress) into a proper port. Vitus Berings two Pacific expeditions (1725–1729 and 1733–1742) brought in large numbers of people and the first scholars and expert sailors and led to a great deal of building. In 1742 there were 57 buildings, 45 other buildings in the Berings "expedition settlement" and eight ships in the harbor. Anton de Vieira, of Portuguese people origin (son of a Jewish father and Christian mother), was the towns governor at that time. From 1737 to 1837 there was a salt works several miles west on the coast that produced 14–36 tons annually. In 1827 it was worked by 150 exiles and about 100 guards and overseers.

How many years was there a salt works several miles from the coast that produced 14-36 tons annually?
Answer: 100

Problem: In the early game the Giants were crushed by the Rams 31–3, thus forcing the 49ers to win their game to clinch the division. In wet, rainy conditions in Oakland, the 49ers dominated the Raiders, 38–7, giving the 49ers their first divisional title, making them champions of the NFC West. The 49ers won their divisional playoff game 17–14 against the defending conference champion 1970 Minnesota Vikings season, thus setting up a matchup against the 1970 Dallas Cowboys season for the NFC championship. In the final home game for the 49ers at Kezar Stadium the 49ers kept up with the Cowboys before losing, 17–10, thus giving the Cowboys their first conference championship. The 49ers sent five players to the 1970 Pro Bowl that season, including MVP veteran quarterback John Brodie, wide receiver Gene Washington (49ers), and linebacker Dave Wilcox. Nolan was also named NFL Coach of the Year for 1970. Following the 1970 season the 49ers moved from Kezar Stadium to Candlestick Park. Despite being located on the outskirts of the city, Candlestick Park gave the 49ers a much more modern facility with more amenities that was easier for fans to access by highway.

Where were the 49ers before Candlestick Park?
Answer: Kezar Stadium

Problem: When Jogaila died in May 1434, the Order resumed its backing for Švitrigaila, who rallied his supporters, including knights from the Livonian Order, the Orthodox dukes, and his nephew Sigismund Korybut, a distinguished military commander of the Hussites. The final Battle of Pabaiskas was fought in September 1435 near Ukmergė , northwest of Vilnius. It is estimated to have involved 30,000 men on both sides. Švitrigaila's army, led by Sigismund Korybut, was split by the attacking Lithuanian-Polish army, led by Michael Žygimantaitis, and soundly defeated. The Livonian Order had suffered a great defeat, sometimes compared to that which had been inflicted on the Teutonic Knights at Grunwald in 1410. On 31 December 1435 the Teutonic Knights signed a peace treaty at Brześć Kujawski. They agreed to cease their support for Švitrigaila, and in the future to support only Grand Dukes who had been properly elected jointly by Poland and Lithuania. The treaty did not change the borders that had been set by the Treaty of Melno in 1422. The Teutonic and Livonian Orders no longer interfered in Polish-Lithuanian affairs; instead, Poland and Lithuania would involve themselves in the Thirteen Years' War , the civil war that would tear Prussia in half.

In what month was Battle of Pabaiskas?
Answer: September

Problem: The French king, John II, had been held captive in England. The Treaty of Brétigny set his ransom at 3 million crowns and allowed for hostages to be held in lieu of John. The hostages included two of his sons, several princes and nobles, four inhabitants of Paris, and two citizens from each of the nineteen principal towns of France. While these hostages were held, John returned to France to try and raise funds to pay the ransom. In 1362 John's son Louis of Anjou, a hostage in English-held Calais, escaped captivity. So, with his stand-in hostage gone, John felt honor-bound to return to captivity in England. The French crown had been at odds with Navarre  since 1354, and in 1363 the Navarrese used the captivity of John II in London and the political weakness of the Dauphin to try to seize power. Although there was no formal treaty, Edward III supported the Navarrese moves, particularly as there was a prospect that he might gain control over the northern and western provinces as a consequence. With this in mind, Edward deliberately slowed the peace negotiations. In 1364, John II died in London, while still in honourable captivity. Charles V succeeded him as king of France. On 7 May 1364, one month after the dauphin's accession and three days before his coronation as Charles V, the Navarrese suffered a crushing defeat at the Battle of Cocherel.

How many years was the French crown at odds with Navarre before Charles V succeeded as king?
Answer:
9
