In a laboratory, three scientists - Dr. Adams, Dr. Brown, and Dr. Clark - are working on separate experiments involving chemical solutions. Each scientist has labeled their solution with their initials and placed them in identical beakers. During lunchtime, an intern named Alex enters the lab to clean up. Unaware of the importance of the labels, he removes them while cleaning the beakers. When the scientists return, how can they determine which solution belongs to whom without conducting any tests or asking Alex? Provide a very brief response.
The scientists can determine which solution belongs to whom by process of elimination based on their knowledge of their own solutions. Each scientist knows the specific characteristics, such as color, viscosity, or smell, of their own solution and can thereby identify which beaker contains their solution by examining the solutions without conducting any formal tests. Upon each scientist identifying their own solution, the remaining beaker by default belongs to the third scientist.
