Final answer:
The character described from 'The Office' does not exist; the statement is false.
Step-by-step explanation:
The statement that the effeminate, pompous, African-American receptionist at the Dunder Mifflin, Utica branch first appears in 'Branch Wars' and later reappears in 'Lecture Circuit' is false. The character in question is actually from the television show 'The Office' which features fictional characters in a mockumentary setting about the day-to-day operations of an office. The character mentioned does not correspond to a known character from the series, as 'The Office' does not have such a character in its Utica branch episodes.
