Complete using the present simple or the present continuous. On market day, people _______ (not go) to the supermarket.

The correct answer is 'do not go'. The sentence describes a typical action on market day, so we use the present simple. 'People' is plural, so the verb 'go' remains in its base form, and 'not go' is constructed with the auxiliary verb 'do'. Therefore, the completed sentence is: 'On market day, people do not go to the supermarket.'
