Final answer:
The sentence 'The king called a meeting' can be expanded with apposition and dizeugma by rephrasing it to 'The king, the sovereign ruler of the kingdom, called a meeting and summoned his council,' where 'the sovereign ruler of the kingdom' is an appositive phrase and 'called' is the single verb governing two actions.
Step-by-step explanation:
To expand the sentence 'The king called a meeting' to include one instance of apposition and one instance of dizeugma, you can rephrase it as follows:
'The king, the sovereign ruler of the kingdom, called a meeting and summoned his council.'
In this expanded sentence, 'the sovereign ruler of the kingdom' is an appositive phrase that renames 'the king' and provides additional information about him. The use of dizeugma is illustrated by the king performing two actions ('called' and 'summoned') that are governed by a single verb, 'called.' This creates a more efficient sentence structure and emphasizes the king's authority and the swiftness of his actions.
