Input: Article: 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.

Now answer this question: What factor especially affected travel to the front in Alsace and Lorraine?

Output: frequent changes between trains

Input: Article: This growing coalition expanded the potential enemies that Rome might face, and moved Rome closer to confrontation with major powers. The result was more alliance-seeking, on the part of both the Roman confederacy and city-states seeking membership (and protection) within that confederacy. While there were exceptions to this (such as military rule of Sicily after the First Punic War), it was not until after the Second Punic War that these alliances started to harden into something more like an empire, at least in certain locations. This shift mainly took place in parts of the west, such as the southern Italian towns that sided with Hannibal.

Now answer this question: What towns had chosen Hannibal's side?

Output: southern Italian

Input: Article: The elevator motor was located at the top of the shaft or beside the bottom of the shaft. Pushing the handle forward would cause the cab to rise; backwards would make it sink. The harder the pressure, the faster the elevator would move. The handle also served as a dead man switch: if the operator let go of the handle, it would return to its upright position, causing the elevator cab to stop. In time, safety interlocks would ensure that the inner and outer doors were closed before the elevator was allowed to move.

Now answer this question: Eventually safety locks were used to guarantee what?

Output:
that the inner and outer doors were closed before the elevator was allowed to move
