Q: Successful mining took time and capital, particularly once most of the timber around the Klondike had been cut down. A realistic mining operation required $1,500  for wood to be burned to melt the ground, along with around $1,000  to construct a dam, $1,500  for ditches and up to $600  for sluice boxes, a total of $4,600. The attraction of the Klondike to a prospector, however, was that when gold was found, it was often highly concentrated. Some of the creeks in the Klondike were fifteen times richer in gold than those in California, and richer still than those in South Africa. In just two years, for example, $230,000  worth of gold was brought up from claim 29 on the Eldorado Creek.
How many operations cost the same price?

A: 2


Q: The 49ers featured one of the best running games in the NFL in 1976 NFL season. Delvin Williams emerged as an elite back, gaining over 1,200 yards rushing and made the Pro Bowl. Wilbur Jackson also enjoyed a resurgence, rushing for 792 yards. Once again Gene Washington was the teams leading receiver with 457 yards receiving and six scores. The 49ers started the season 6–1 for their best start since 1970. Most of the wins were against second-tier teams, although the 49ers did shut out the Rams 16–0, in 1976 Los Angeles Rams season on Monday Night Football. In that game the 49ers recorded 10 sacks, including 6 by Tommy Hart. However, the 49ers lost four games in a row, including two against divisional rivals Los Angeles and 1976 Atlanta Falcons season that proved fatal to their playoff hopes. Louis G. Spadia retired from the 49ers in 1977 upon the teams sale to the DeBartolo Family. The team was sold to Edward J. DeBartolo Jr. in March 1977, and despite finishing the season with a winning record of 8–6, Clark was fired after just one season by newly hired general manager Joe Thomas (American football executive), who oversaw the worst stretch of football in the teams history.
How many games did the 49ers win than lose for their best start in 1970?

A: 5


Q: There was interest in his ideas but they remained untested; this changed with the outbreak of the 1688-1697 Nine Years War which placed great emphasis on manoeuvre and siege warfare. Van Coehoorn was present at the capture of Kaiserswerth and Bonn in 1690; his exact role is unclear but Frederick of Prussia was impressed enough to offer him a position as Major-General in his army. He refused and in 1691 William appointed him commander of Namur where he was finally able to implement his ideas on defensive strategy. Namur was divided into the 'City' on the flat northern bank of the River Sambre and the Citadel on high ground to the south controlling access to the Sambre and Meuse rivers. Van Coehoorn strengthened the 'inner' Citadel with new outworks at Fort William and La Casotte but did not have time to do the same for the 'outer' City area. His garrison of 5,000  was also too small for the active defence he had planned, many being poorly-trained Spanish troops with little interest in fighting for the Dutch.
Who refused to appoint him commander of Namur?

A: Van Coehoorn


Q: Ivan III considered himself an heir to the fallen Byzantine Empire and defender of the Orthodox Church. He proclaimed himself sovereign of all Rus' and claimed patrimonial rights to the former lands of Kievan Rus'. Such ambitions led to the steady growth of Muscovite territory and power. The Mongol Yoke ended in 1480 with the defeat of Akhmat Khan of the Golden Horde in the Great stand on the Ugra river. Moscow extended its influence to the Principality of Ryazan in 1456, annexed the Novgorod Republic in 1477, and the Principality of Tver in 1483. Further expansionist goals of Ivan III clashed with the Lithuanian interests. Around 1486-87, territories along the ill-defined Lithuanian-Muscovite border in the upper reaches of the Oka River were under attack by Muscovy, allied with Meñli I Giray, khan of the Crimean Khanate. Tensions continued to rise. In August 1492, without declaring war, Ivan III began large military actions: he captured and burned Mtsensk, Lyubutsk, Serpeysk, and Meshchovsk; raided Mosalsk; and attacked territory of the Dukes of Vyazma. Orthodox nobles began switching sides to Moscow as it promised better protection from military raids and an end to religious discrimination by Catholic Lithuanians. Ivan III officially declared war in 1493, but the conflict soon ended. Grand Duke of Lithuania Alexander Jagiellon sent a delegation to Moscow to negotiate a peace treaty. An "eternal" peace treaty was concluded on February 5, 1494. The agreement marked the first Lithuanian territorial losses to Moscow: the Principality of Vyazma and a sizable region in the upper reaches of the Oka River. The lost area was estimated to be approximately 87,000 km2 . A day before the official confirmation of the treaty, Alexander Jagiellon was betrothed to Helena, daughter of Ivan III .
