Step-by-step explanation:
Benjamin Banneker's clock kept perfect time for 40 years before being destroyed by fire. As a self-taught clockmaker, and astronomer, Banneker meticulously crafted the clock from wood in 1753. The clock's duration of operation showcases his profound skill and ingenuity. His contributions highlight significant achievements in early American history and underscore the importance of intellectual property in fostering innovation, similarly reflected in the typical 21-year time period for a patent.
Banneker's story also aligns with broader discussions on intellectual property, as seen in the 21-year duration of a patent—a legal acknowledgment of an inventor's rights, reflecting the societal value placed on fostering innovation and protecting the fruits of intellectual labor.
