The effect of these differences was accentuated by the pre-war preparations. The Prussian General Staff had drawn up minutely detailed mobilization plans using the railway system, which in turn had been partly laid out in response to recommendations of a Railway Section within the General Staff. The French railway system, with multiple competing companies, had developed purely from commercial pressures and many journeys to the front in Alsace and Lorraine involved long diversions and frequent changes between trains. Furthermore, no system had been put in place for military control of the railways, and officers simply commandeered trains as they saw fit. Rail sidings and marshalling yards became choked with loaded wagons, with nobody responsible for unloading them or directing them to the destination.
What was one factor behind the inefficiency of the French railway system?
A: multiple competing companies

In 1353 Bern joined the Swiss Confederacy, becoming one of the eight cantons of the formative period of 1353 to 1481. Bern invaded and conquered Aargau in 1415 and Vaud in 1536, as well as other smaller territories; thereby becoming the largest city-state north of the Alps, by the 18th century comprising most of what is today the canton of Bern and the canton of Vaud.
How many cantons were there between 1353 to 1481?
A: 8

New Haven lies in the transition between a humid continental climate (Köppen climate classification: Dfa) and humid subtropical climate (Köppen Cfa), but having more characteristics of the former, as is typical of much of the New York metropolitan area. Summers are humid and warm, with temperatures exceeding 90 °F (32 °C) on 7–8 days per year. Winters are cold with moderate snowfall interspersed with rainfall and occasionally mixed precipitation. The weather patterns that affect New Haven result from a primarily offshore direction, thus reducing the marine influence of Long Island Sound—although, like other marine areas, differences in temperature between areas right along the coastline and areas a mile or two inland can be large at times.
New Haven's climate is largely analogous to what major adjoining metropolitan area?
A:
New York
