Which tense represents action that took place in the past?

The tense that accurately represents action that took place in the past is the Past tense. This tense is used to describe events that have already happened, often indicated by specific time references like "yesterday," "last year," or "in 1999." It conveys a sense of completion because it focuses on actions that are no longer ongoing.

For instance, in the sentence "She walked to the store," the use of the Past tense clearly shows that the action of walking occurred in the past and is not currently in progress. This clarity in indicating past actions is what makes this tense the correct choice for representing actions that occurred before the present time.
