What was a direct result of Austria's Nazi support in terms of local governance?

The support of Austria for Nazi Germany led to a surge in rallies, protests, and riots as the local governance was heavily influenced by the oppressive measures of the Nazi regime. This period saw an increase in political activism as various groups either supported or resisted the Nazi agenda. The regime's propagandistic initiatives and suppression of dissent often spurred public demonstrations, highlighting the tensions present in Austrian society at the time.

In contrast, the other options do not accurately reflect the direct outcomes of the local governance under Nazi influence. For instance, while increased tension between social classes may have existed, it was more of a result of the overall societal impact rather than a direct consequence of governance structure under Nazi control. Similarly, while protests and riots did occur, suggesting that the local government encouraged such actions contradicts the authoritarian nature of the regime that sought to suppress dissent rather than foster it. Taxes being significantly reduced would not align with the economic policies of Nazi governance aimed at military expansion and war preparation, which tended to impose heavier burdens on the populace. Finally, while some political alliances may have been affected due to Nazi support, the regime's tendency was to centralize power and eliminate opposition, making this option less applicable in the context of direct local governance changes.
