Complete using the present simple or the present continuous. He _______ (sell) fruit, but he _______ (not sell) fruit now.

The correct answers are 'sells' and 'is not selling'. The first sentence describes a regular activity, therefore we use the present simple. Since 'he' is a singular third-person subject, we add an 's' to the verb 'sell'. The second sentence uses the word 'now', which indicates an action happening at this moment, so we use the present continuous. Thus, we need to use 'is not selling'. Therefore, the completed sentences are: 'He sells fruit, but he is not selling fruit now.'
