At the end of the last ice age, what are now the British Isles were joined to the European mainland as a mass of land extending north west from the modern-day northern coastline of France, Belgium and the Netherlands. Ice covered almost all of what is now Scotland, most of Ireland and Wales, and the hills of northern England. From 14,000 to 10,000 years ago, as the ice melted, sea levels rose separating Ireland from Great Britain and also creating the Isle of Man. About two to four millennia later, Great Britain became separated from the mainland. Britain probably became repopulated with people before the ice age ended and certainly before it became separated from the mainland. It is likely that Ireland became settled by sea after it had already become an island.

When sea levels rose what occured in the British Isles area?
Answer: separating Ireland from Great Britain

Hanover was founded in medieval times on the east bank of the River Leine. Its original name Honovere may mean "high (river)bank", though this is debated (cf. das Hohe Ufer). Hanover was a small village of ferrymen and fishermen that became a comparatively large town in the 13th century due to its position at a natural crossroads. As overland travel was relatively difficult, its position on the upper navigable reaches of the river helped it to grow by increasing trade. It was connected to the Hanseatic League city of Bremen by the Leine, and was situated near the southern edge of the wide North German Plain and north-west of the Harz mountains, so that east-west traffic such as mule trains passed through it. Hanover was thus a gateway to the Rhine, Ruhr and Saar river valleys, their industrial areas which grew up to the southwest and the plains regions to the east and north, for overland traffic skirting the Harz between the Low Countries and Saxony or Thuringia.

What did Hanover possibly originally mean?
Answer: "high (river)bank"

In the following two decades after Sianis' ill will, the Cubs played mostly forgettable baseball, finishing among the worst teams in the National League on an almost annual basis. Longtime infielder/manager Phil Cavarretta, who had been a key player during the '45 season, was fired during spring training in 1954 after admitting the team was unlikely to finish above fifth place. Although shortstop Ernie Banks would become one of the star players in the league during the next decade, finding help for him proved a difficult task, as quality players such as Hank Sauer were few and far between. This, combined with poor ownership decisions such as the College of Coaches, and the ill-fated trade of future Hall of Famer Lou Brock to the Cardinals for pitcher Ernie Broglio (who won only 7 games over the next three seasons), hampered on-field performance.

What season was Phil Cavarretta a key player for the Cubs?
Answer:
the '45 season
