Final answer:
The correct answer to the discussion roles is a sender and a receiver. In persuasive communication, analytical and motivated audiences are most receptive. Agents of political socialization include family, religious leaders, and teachers, but not U.S. senators.
Step-by-step explanation:
In discussions, the correct answer is that there is always a sender and a receiver. The sender is the one who imparts information or expresses their thoughts, while the receiver is the one who gets the message and interprets it. The effectiveness of the central route to persuasion relies on the audience being analytical and motivated.
Dialectics involve an interlocutor who responds to a question and participants who critically examine the response, offering counterexamples and scrutinizing the reasoning behind the answers.
When considering agents of political socialization, a U.S. senator is not typically seen as a direct agent like family members, religious leaders, or teachers. Lastly, the term 'disinterested' refers to someone who is impartial, while 'uninterested' describes someone who lacks interest in the topic at hand.
