The sentence with correctly punctuated compound adjectives is:
- The "well known" athlete was recognized wherever she went.
In this case, "well known" is correctly punctuated as a compound adjective. The others contain errors in punctuation or structure related to their compound adjectives. For example, "man eating" should be hyphenated as "man-eating," and "three page" should be "three-page." "Next door" and "warm hearted" should also be hyphenated as "next-door" and "warm-hearted."
