Final answer:
Food was particularly scarce in Europe after the war due to disrupted agricultural production and factors such as the British blockade of Germany. Rationing and shortages of food became common.
Step-by-step explanation:
The commodity that was particularly scarce in Europe after the war was food. The war had disrupted the agricultural production, and the countries were facing food shortages. This was compounded by factors such as the British blockade of Germany and the redirection of occupied Norway's production to supply German needs. Rationing and shortages of food became common, and people had to line up for scarce and rationed goods.
