Here's a question and a few possible answers: 

Q: Sam drove to the city square and noticed that the lines weren't quite right.  It was a few degrees off, most like a trapezoid.   What might Sam be interested in?
Possible A: architecture, geometry, fifties, town center, four corners

Why is "geometry" an answer aligned with human common sense? 


trapezoid is a geometric figure and geometry studies lines and angles.
