Final answer:
The non-compete clause in the neurosurgeon's contract specifies that the seller will not practice within a 100-mile radius of Chicago for one year.
Step-by-step explanation:
When a nationally known neurosurgeon in Chicago, Illinois, sells her practice, the contract may specify a non-compete clause. The question presents a scenario where the contract specifies that the seller (neurosurgeon) will not practice within a certain radius of Chicago for a specified time period. The correct statement according to the scenario provided would be:
The seller will not practice within a 100-mile radius of Chicago for one year.
This type of clause is included to prevent the seller from competing with the new owner of the practice within the agreed-upon area and time frame. It is crafted to protect the practice's existing patient base and the investment of the buyer.
