The past perfect 'had completed' is required because the action of completing the repairs was finished before a separate past event—the supervisor's arrival.

The cue word 'Listen!' signals that the action is happening at this very moment, making the present continuous 'is playing' the correct choice.

Present continuous with 'always'—'is always forgetting'—is the standard construction for expressing irritation or complaint about a recurrent habit.

The present perfect continuous 'has been living' is appropriate because the action began at a past point ('since she was a child') and continues up to the present moment.

The time expression 'so far' signals an action measured up to the present, which calls for the present perfect 'has won'.

The simple past 'took' is correct for describing a habitual past routine, confirmed by the past-time framing 'when he lived in the countryside'.

The past continuous 'were waiting' describes the ongoing background activity that was interrupted when a sudden event ('began to rain') occurred.

The future perfect 'will have reached' is required to indicate that the decision will be fully made before a specific future deadline ('by the time the manager returns').

'Shall' is the conventional auxiliary used with first-person subjects ('we') in questions that extend a polite suggestion or invitation.

The future perfect continuous 'will have been teaching' is needed to project forward and emphasize the total unbroken duration of an activity right up to a stated future point.
