Final answer:
The election process for a commissioner varies by location, and without context, we cannot definitively say it's true or false that a commissioner must be elected in a general election.
Step-by-step explanation:
Regarding commissioners and their elections, the process can vary depending on the state or locality in question. While in some places a commissioner might indeed be elected in a general election, it is not a universally applicable truth for all commissioners across different governmental levels or jurisdictions. Therefore, without a specific context or location, the statement 'The commissioner must be elected in a general election' is not necessarily true or false; it requires clarification and context.
