Identify the redundant word in the sentence about credit card rates.

In the context of the sentence about credit card rates, the word "back" is redundant because it often serves as a preposition or adverb that implies returning to a previous state or condition. When discussing credit card rates, using the word "revert" alone effectively conveys the idea of returning to earlier rates without the need for "back."

In this scenario, "low" would describe the type of rates, and "complete" might relate to the overall context of the information being shared. However, "back" does not add any new information. Therefore, its removal would streamline the sentence and enhance clarity without losing the original meaning.
