Here is the sentence:
Starving but broke, Rhonda called Aunt Martha, whose generous nature and
well-stocked cupboards would provide Rhonda with enough food until payday.
Good job! Starving but broke, a participle phrase, comes right before the noun Rhonda. Whose generous nature and well-stocked cupboards would provide ..., an adjective clause, comes right after the noun Aunt Martha. These are clear and logical pairings of targets and modifiers. There are no errors.
