1011.5: Seminar Seating

 

 

Six philosophy students are waiting around a small table for their seminar to begin.

 

 

 

Arthur, Cora, and Elizabeth are majors. Bas, David, and Frances are minors. Arthur and Bas are sitting to the immediate left of a major. Cora and David are sitting to the immediate right of a minor. Elizabeth and Frances sit directly across from a minor. The person presenting his seminar paper is on the immediate left of a major, and directly across from a minor.

 

 

Questions

 

1. Who is presenting?

 

2. Can you draw two distinct seating charts that satisfy all the constraints? (Two charts are distinct if they are not congruent under any transformation of the plane. In other words, two charts are different if the order of persons going around the table is different.)
