What larger crisis did bread queues indicate in the February Revolution?

Correct answer: Urban food supply and failure of governance

The governing concept is the connection between an everyday shortage and a wider political crisis. Bread queues in Petrograd were not merely signs that people wanted food; they reflected failures in supplying and distributing essential goods during wartime. Inflation, transport disruption, shortages and administrative weakness made daily life extremely difficult for urban workers and families. When authorities could not respond effectively, economic hardship turned into public anger and demonstrations. The queues therefore indicated both an urban food-supply crisis and a failure of governance. Palace decoration, election preparation and successful foreign trade do not account for the queues. Hence option A is correct.
