Answer Details

The word or group of words that best completes the sentence is "in exchange for". The phrase "in exchange for" means to give something and receive something else of equivalent value in return. In the context of the sentence, it means that people used to give cowries as a means of exchange for food. The phrase "on exchange for" is not grammatically correct. The correct preposition to use with "exchange" is "in". The phrase "in exchange of" is also incorrect. The correct preposition to use with "exchange" is "for". The phrase "on exchange with" is not appropriate in this context. It implies an exchange between two parties or individuals, rather than a means of exchange for goods or services. Therefore, the best word or group of words to complete the sentence is "in exchange for".
