How did Twilly accumulate his wealth?

The correct answer highlights that Twilly accumulated his wealth through inheritance from his grandfather. Inheritance typically represents a transfer of wealth that can significantly impact an individual's financial status without the need for traditional forms of earning money, such as working jobs or starting a business. This method of acquiring wealth is often seen in narratives and case studies, where familial ties play a crucial role in financial stability and growth.

While working several jobs, winning the lottery, or selling a successful business are all legitimate means of wealth accumulation for individuals, they imply efforts, risks, or entrepreneurial success, which are absent in the inheritance scenario. This option directly indicates a financial boost received without personal endeavor, making it uniquely positioned among the choices.
