main and subordinate clauses\nadd a main clause to make this a complete sentence again.\nwhen it got dark, _?\non the lamp\nshe turned on the lamp\nturns on

Answer

Brief Explanations:

A main clause must have a subject and a verb. "on the lamp" is a prepositional phrase. "turns on" is a verb phrase without a subject. "she turned on the lamp" has a subject "she" and a verb "turned", making it a valid main clause.

Answer:

she turned on the lamp
