Identify the term that names the first entrant in the described seating arrangement.

• A. Colonel
• B. Captain
• C. Sergeant
• D. Junior

Answer: (D)

In seating or enrollment sequences, the label chosen for the first entrant often signals their position in the order or their relative age in a paired naming scheme. Junior is the natural fit because it denotes someone who is first or younger within a hierarchy or sequence. That makes it the best descriptor for the opening entrant. The other terms refer to ranks that imply authority or seniority rather than the starting position in a line, so they don’t fit as naming the first entrant.
