Suppose the new restaurant in town, Bistro 27, has received rave reviews from local food critics. Customers have been flocking to the restaurant to try their specialty dishes. The owner of Bistro 27, Chef Maria, has previously worked at several Michelin-starred restaurants in Europe before opening her own establishment in the United States.
Can we infer that "Chef Maria has never worked in a restaurant before opening Bistro 27"? Yes, no, or maybe?
