Final answer:
The question about what happened to Frank's ex-wife after their divorce lacks context, making it impossible to answer definitively without more information. Possible scenarios include remarriage, relocation, custody arrangements, or starting a new job.
Step-by-step explanation:
The question "Frank legally divorced his wife last year. His ex-wife ________?" requires additional context to provide a definitive answer. Without specific details, it's impossible to know whether Frank's ex-wife remarried, moved to another country, got custody of their children, or started a new job. Each of these options represents a possible scenario following a divorce. In family law, these outcomes depend on individual circumstances and legal proceedings.
