Answer:
Motive, Crime of Passion and Sam is a suspect
Explanation:
Motive for killing a person will be determined by the intent to kill in terms of the circumstance surrounding at the very moment. If Sam's wife had committed the act as he claims and then she is now missing this leads to a motive if she is found dead.
A Crime of Passion may have also occurred if he was distraught by hearing the news that he was betrayed. In that instant he may have lost his judgement and committed a crime, if, in fact, she is found dead.
However if is very likely that Sam is a suspect in his wife's disappearance as he was the last person to have been with her right before he disappeared. Not only this but he was heard saying that harm may come to her which establishes that they were not on good terms.
There are several reasons why group problem-solving and decision making is more likely to produce the correct answer than in an individual setting.
One reason is that groups who act in a cooperative manner tend to do better than individuals, who are in a more competitive atmosphere. Group interaction facilitates collaboration, fresh ideas, and improved solutions.
Another reason why groups tend to do better is that a group has a better collective memory than one person does.
Lastly, a group working together can draw upon each other's strengths and talents, making the group more well-rounded and resource rich.
