Jamal attended the campus president's speech about tuition increases, while Mary listened to a podcast of the speech in her car. Later, Mary said she thought the president's words stated clearly that he opposed an increase in tuition. But Jamal said that the way the president avoided looking at students when he talked about tuition made it seem like the president actually supported an increase in tuition. The difference in the messages Mary and Jamal received most likely resulted from the fact that:_______.
A- Jamal is better listener than Mary.
B- Mary and Jamal both experienced feedback.
C- Mary and Jamal received the message through different channels.
D- Mary and Jamal are majoring in different subjects.
E- Mary is better listener than Jamal.

From the passage above, it can be deduced that Jamal was present physically when the president gave the speech on campus while Mary listened to the speech through while in her car. so the medium by which both of them received the speech is different, one was present, while the other was absent and the one present was able to give details of the actual behavior of the president while giving the speech while the other only could hear what was said. So the difference in messages Mary and Jamal received resulted from the different channels through which they received the message. Option C is the answer.
