Step-by-step explanation:
The Kreutzer violin was created in Italy in 1727. To calculate its age when it was sold in 1998, we subtract the year of creation from the year it was sold:
- Determine the year the violin was made: 1727.
- Determine the year the violin was sold: 1998.
- Subtract the year of creation from the year it was sold: 1998 - 1727 = 271.
Therefore, the violin was 271 years old when it was sold. The correct answer is: a. 271 years.
