A professor decides to save paper by posting her syllabus on the university's web$-$based course application

program instead of printing it and handing it out during the first class. She sends an e$-$mail to all her

students prior to the actual start of the course that reads, "Your syllabus is available on our online learning

management system. I will go over that syllabus during the first class but, since I am attempting to conserve

paper, will not make a copy available to you. Students, however, are welcome to print out their own copy of

the syllabus." Students come to class and ask why they are not receiving syllabi. This question represents

what aspect of the communication model?
