Answer:
To study the processes by which past behaviour influences future behaviour, participants were led to believe that without being aware of it, they had expressed either support for or opposition to the institution of comprehensive exams. Judgment and response time data suggested that participants’ perceptions of their past behaviour often influenced their decisions to repeat the behaviour. This influence was partly the result of cognitive activity that influenced participants’ cognitions about specific behavioural consequences and the attitude they based on these cognitions. More generally, however, feedback about past behaviour had a direct effect on participants’ attitudes and ultimate behavioural decisions that were independent of the outcome-specific cognitions. Results are discussed in terms of their implications for biased scanning of memory, dissonance reduction, self-perception, and the use of behaviour as a heuristic.
Your tone
Let's look at the other choices first. Your credibility is your ability to be believed as trustworthy in regards to the subject. Whether you're talking to a group of teenagers or professional adults, your credibility doesn't change. Your clarity also should not change based on the audience because you want to be clear in your message at all times. Also, your purpose should be the same no matter the audience. The only thing that would change is your tone. The way you approach a crowd of teenagers would vary greatly from the way you'd approach a room of professionals.
Answer: A) After the ceasefire was declared, the soldiers were allowed to go home.
Explanation:
An independent clause is a clause that expresses a complete thought. It can stand on its own and still make sense. The independent clause in this example is "the soldiers were allowed to go home."
A subordinate clause, on the other hand, is a clause that does not express a complete thought. It cannot stand alone, because it has no meaning if not joined to an independent clause. "After the ceasefire was declared" is a subordinate clause.
All the other options contain two independent clauses - in option B, they are connected with a semicolon; in option C, with a conjunction "so"; in option D, with a comma and a conjunction "and."
