Common Sense Challenge Problem: Singin' in the Rain/title> </head> <body bgcolor="#ffffff" text="#000000"> <h2> <font color="green"> From the <a href="http://www-formal.stanford.edu/leora/commonsense">Common Sense Problem Page</a> </h2> <font color="black"> <h3><i>Physical Reasoning</i></h3> <font color="green"> <h3>Singin' in the Rain</h3> <font color="black"> <p> It is necessary to walk several hundred yards in rain. Explain why if the rain is moderate then one should run, but not if one has an umbrella; but if the rain is very heavy then running is of no use unless one has an umbrella, and even then it is best to hurry; and if there is also a strong wind one is likely to get more wet than if not, even with an umbrella. <p> <b>Contributed by</b> <a href="http://www.coginst.uwf.edu/%7Ephayes/"> Pat Hayes</a> (<a href="mailto:phayes@ai.uwf.edu"> phayes@ai.uwf.edu</a>), Institute for the Interdisciplinary Study of Human and Machine Cognition, University of West Florida, U.S.A.
