Final answer:
The subject of the sentence is 'Millie', with the verbs being 'attended' and 'became'. 'Millie' performs the actions of attending culinary school and becoming a chef, making 'Millie' the subject of both verbs.
Step-by-step explanation:
The sentence in question is: "After leaving home, Millie attended culinary school and became a chef." The subject of the sentence is 'Millie', with the verbs being 'attended' and 'became'. 'Millie' performs the actions of attending culinary school and becoming a chef, making 'Millie' the subject of both verbs.
To identify the subject of this sentence, we first locate the verbs, which are 'attended' and 'became'. By asking 'who attended?' and 'who became?', we can ascertain that 'Millie' is the subject of the sentence performing the actions.
The verbs here are 'attended', which is a transitive verb (as it requires an object 'culinary school'), and 'became', which is a linking verb connecting the subject to a subject complement ('a chef'). Prepositional phrases like 'After leaving home' serve as adverbials and do not contain the subject of the sentence.
