All the following except one are the communes of the colony of Senegal where the Policy of Assimilation was applied

Out of the given options, all are communes of the colony of Senegal where the Policy of Assimilation was applied except "Kaolack." The Policy of Assimilation was a French colonial policy that aimed to assimilate the indigenous populations of their colonies into French culture and society. The policy was implemented in different ways in different colonies, but in Senegal, it was implemented through a system of communes. Under the system of communes, certain cities were designated as communes and were given a greater degree of autonomy and self-government. These communes were also opened up to non-French citizens, including the indigenous population, who could become full French citizens by adopting French culture and values. The four communes mentioned in the question, Saint Louis, Rufisque, Goree, and Kaolack, were all part of the colony of Senegal, but only the first three were the communes where the Policy of Assimilation was applied. Kaolack was not designated as a commune until 1914, which was after the implementation of the Policy of Assimilation. Therefore, the correct answer is "Kaolack," as it is the commune that was not part of the Policy of Assimilation in the colony of Senegal.
