Final answer:
The phrase 'Because apart from the' functions as an adverbial of cause, which provides the reason or circumstances prompting an action in a sentence.
Step-by-step explanation:
The phrase 'Because apart from the' suggests an adverbial of cause. Adverbials can function in various ways in a sentence. They modify verbs to give more information about the time, place, manner, or cause of the action.
For instance, if we use 'because' in a sentence like 'She left because she was ill,' it establishes a cause for the action of leaving. Therefore, when we are concerned with the reasons, reasons, or circumstances that prompt an action, we are dealing with an adverbial of cause.
Remember, conjunctive adverbs like 'indeed' and 'besides' serve to join ideas together but should not be confused with subordinating conjunctions that introduce adverbial clauses.
