Final answer:
The sentence should be completed with a past tense verb such as 'made' or 'cooked', resulting in the sentence 'We were hungry so mum made food for dinner?'. This fits the context of family meal preparation implied in the various narrative excerpts provided.
Step-by-step explanation:
The sentence 'We were hungry so mum ______ food for dinner?' should be filled in with a verb that confirms an action done by 'mum' in past tense given the context presented. Considering the various narrative excerpts provided, which emphasize home-cooked meals, preparing food, and family dinners, an appropriate verb could be 'made' or 'cooked'. Therefore, the completed sentence is 'We were hungry so mum made food for dinner?'
It's clear from the context that 'mum' has taken the initiative to prepare a meal to satisfy the hunger mentioned at the beginning of the sentence. The act of making or cooking food is a common familial activity, something underscored in the narratives showing a connection between family members and the preparation or enjoyment of meals together.
