Complete these sentences using the verbs in brackets in the passive voice. Some programmes _______ (to show) live but most of them are recorded on film or videotape.

{"solution": "The sentence requires the verb 'to show' to be in the passive voice. Since 'some programmes' is plural, we should use the plural form of the auxiliary verb 'to be' in the present tense, which is 'are'. Then, we add the past participle of 'show', which is 'shown'. So, the completed sentence is: Some programmes are shown live but most of them are recorded on film or videotape.", "answer": "are shown"}
