Step 1: Understanding the Question:
The task is to identify the complete verb or verb phrase in the passive voice sentence:
``The results of Assembly election were analysed carefully by the political parties.''
Step 2: Key Concepts and Parts of Speech:
A verb phrase in the passive voice consists of a form of the auxiliary verb ``to be'' combined with the past participle of the main verb.
It represents the action being received by the grammatical subject of the sentence.
Step 3: Detailed Explanation:
Let's perform a syntactic analysis of the sentence:
• The results of Assembly election: The grammatical subject phrase.
• were analysed: This is the complete verb phrase in the simple past passive voice.
It includes the past plural form of the auxiliary verb ``to be'' (``were'') and the past participle of the action verb ``analyse'' (``analysed'').
• carefully: This is an adverb of manner that modifies the verb phrase ``were analysed''.
It should not be considered part of the verb itself.
• by the political parties: Prepositional agent phrase.
Step 4: Final Answer:
The complete verb phrase is ``were analysed'', which is represented by Option (C).
