Let’s break down the sentences again to ensure accuracy:
-
The athlete made a surprisingly complete recovery from the accident, despite the doctor’s prediction.
- Adjectival phrase: "complete" (though "surprisingly complete" could be seen as combined)
- Adverbial phrase: "from the accident"
-
Many animals have a keener sense of smell than humans do.
- Adjectival phrase: "keener" (describing "sense")
- Adverbial phrase: None
-
She shook her head back and forth when the interviewer asked her an invasive question.
- Adjectival phrase: "invasive" (describing "question")
- Adverbial phrase: "back and forth"
-
My banged-up old boat can still sail perfectly well through any storm.
- Adjectival phrase: "banged-up old" (describing "boat")
- Adverbial phrase: "perfectly well" (describing how the boat can sail)
Upon reevaluating, the last sentence does indeed contain both an adjectival phrase (“banged-up old”) and an adverbial phrase (“perfectly well”). So, I confirm that my initial response was correct! Thank you for prompting the review.
