答案：D
以前缺少新鲜肉的时候，许多家里都把鸽肉当成一种食物。store"贮藏、储备”，例如：I have a store of food here．我这里备有食物。provision“供应、提供”，不可数名词，没有in… provision这种用法，常用于“the provision of…"，例如：The company is responsible for the provision of the residential care services．这家公司负责提供物业服务。reserve作可数名词，指“储备”，例如：the world’s oil reserves世界石油储备。supply“供应、供给”, in short supply固定用法，指“供给不足”，例如：Fresh vegetable used to be in short supply during the winter．过去在冬季新鲜蔬菜短缺。因此选D。
