Which surname denotes the father and son who authored the two-volume Kentucky sketches and is the correct answer to a question about their last name?

• A. Adams
• B. King
• C. Fletcher
• D. Collins

Answer: (D)

The idea is to identify a father-and-son pair who collaborated on a two-volume work about Kentucky, and the surname that appears in bibliographic credits for that duo is Collins. In records of this particular set, the Kentucky sketches are attributed to a Collins family, a father and his son, so the last name that fits the question is Collins. The other names—Adams, King, Fletcher—do not have a well-known father-and-son duo linked to those two volumes in standard references. If you ever want to verify, checking the front matter or a library catalog entry for the two-volume Kentucky sketches will show the authors as Collins (father and son) and confirms the surname.
