Dr. Sardonicus divided her first-period class into two groups. One group had to read 20 pages in a boring psychology text but would get 2 extra points on the next test

The other group also read 20 pages but was given 25 points added to the next test. The class members were then asked to tell the second-period class how interesting the book was. According to the results of the Festinger and Carlsmith study, what predictions could one make about the remarks of the first-period class? a) Both groups would say the pages were boring. b) The first group (2 points) would say the pages were boring but the second group (25 points) would not. c) Both groups would say the pages were interesting. d) The first group (2 points) would say the pages were interesting but the second group (25 points) would say the pages were boring.
