Suppose Alex bought a new car from a dealership last month. Since then, Alex has noticed some strange noises coming from the engine whenever he accelerates. He took the car to the dealership's service center for inspection, and they told him that there is a problem with the transmission that needs to be fixed. However, they assured Alex that the repairs would be covered under the car's warranty.
Can we infer that "Alex purchased the car without a warranty."? Yes, no, or maybe?
