Whenever Joe's car is vacuumed, the employees of K & L Auto vacuum it; they are the only people who ever vacuum Joe's car. ██ ███ █████████ ██ █ █ █ ████ ████████ █████ ████ ████ ███ ████ ███ ███ ██ █ █ █ ████ ██ ██ ██████ █████ ███ ███ ████████ █████████ ██████████ ███ ████ ███ ███ ██ █ █ █ ████ ██ ██ ██████
Method of Reasoning
The argument proceeds by triggering a chain of sufficient conditions. If Joe’s car is vacuumed, then K & L employees—and only them—did the vacuuming. If K & L employees do the vacuuming, the Joe’s car was in their shop to be fixed. Since Joe’s car was recently vacuumed, the author implicitly infers that the K & L employees must have done it. From this, the author concludes that Joe’s car must have been taken to the shop to be fixed.
