The sentence that contains both an adjectival phrase and an adverbial phrase is:
The athlete made a surprisingly complete recovery from the accident, despite the doctor’s prediction.
In this sentence:
- "surprisingly complete" acts as an adjectival phrase modifying "recovery."
- "from the accident" is an adverbial phrase explaining the circumstances of the recovery.
(Note: Other sentences may have phrases that could be argued as either adjectival or adverbial, but this one clearly contains both.)
