Final answer:
Sergeant Major Morris in 'The Monkey's Paw' is not a round character as he lacks complexity and development, making the statement false.
Step-by-step explanation:
In The Monkey's Paw by W.W. Jacobs, the character Sergeant Major Morris is not typically considered a round character. A round character is one who is complex, with many traits, and undergoes development, sometimes sufficiently to surprise the reader. Sergeant Major Morris, on the other hand, appears in the story only briefly and serves primarily as a plot device to introduce the cursed monkey's paw to the White family.
His character remains quite mysterious, and his backstory and motivation are not deeply explored, which makes him more of a flat character. It would be appropriate to say that the statement 'Sergeant Major Morris is a round character' is false.
