Final answer:
The sentence provided is a simple sentence as it has one independent clause with a subject and verb expressing a complete thought.
Step-by-step explanation:
The sentence 'He roamed from chamber to chamber with hurried, unequal, and object-less step.' is neither a compound nor a complex sentence. It is a simple sentence because it contains one independent clause and does not have any dependent clauses.
An independent clause is a group of words that contains a subject and verb and expresses a complete thought, which is the case with this sentence. The subject is 'He' and the predicate is 'roamed from chamber to chamber with hurried, unequal, and object-less step,' which together form a complete thought.
