Why could the flour needed by Russian women to bake breads not be received?

It's impossible to give a definitive answer without more context. The reason for Russian women not receiving flour could be due to a variety of factors, spanning across different historical periods and situations.

Here are some potential reasons:

* War or Conflict: Wartime shortages, blockades, or disruptions in transportation could prevent flour from reaching certain areas.

* Famine: A widespread lack of food, including flour, could be caused by crop failures, natural disasters, or political instability.

* Economic Crisis: Poverty or economic hardship could make it difficult for people to afford flour, even if it's available.

* Government Policies: Government regulations or restrictions on flour production or distribution could lead to shortages.

* Transportation Issues: Poor infrastructure, lack of transportation resources, or transportation disruptions could prevent flour from reaching its destination.

To better understand the situation, you'd need more specific information about:

* The time period in question: Were you thinking of a specific historical event or a general situation?

* The location: Was this a widespread problem in Russia or a more localized issue?

* The context: Was there a specific event or situation that led to the flour shortage?
