Task: Question Answering
Input (English): Passage: Prof. Post is a shy Classics professor at Potts College, who has lived a sheltered life and has little experience of life outside of academia. Feeling that the professor should see more of the real world, his assistant tricks the professor into thinking that he has inherited $750,000, allowing the professor to leave academia and see the world.

Boarding a train bound for New York City, Prof. Post encounters James, the manager of a dancing troupe that has an engagement in the backwater town of Fish's Switch. The professor becomes infatuated with one of the dancers, Pansy Peets, and accidentally alights at Fish's Switch when attempting to learn her name. He attends a performance by the dancing troupe at the local theatre, and is impressed by their act.
Feeling that the troupe should continue their act, the professor finances the troupe and takes them to perform on Broadway, but only after James insists that the act be improved to a higher standard. Post's suggestions of using inspiration from Ancient Greece are taken on board, with some minor alterations, and the show is turned into a grandiose musical revue. Although Post wishes that Pansy be the leading lady, the show is quickly turned into a star-vehicle for spoiled actress Eleanor Espere, who attempts to win over the professor in order to take total control over both the show and the money it is expected to earn at its debut. Pansy attempts to warn the professor of Eleanor's bad influence, with mixed results.
On the night of the show's debut, James discovers that Prof. Post does not really have the $750,000 he believes to possess and attempts to keep him away from the production for fear of ruining it. The professor stumbles on-stage at several points, amusing the audience who think it to be part of the act, and ensuring the success of the show. However, his antics cause Eleanor to throw a tantrum, and Prof. Post is finally able to admit his love to Pansy. 
Question: Who is impressed by the dancing troupe's act?
Output (English): Prof. Post.
