The correct answers are
While completing a task with his teammates, Alfred has some solutions he wants to propose...Language barrier
Terri has been asked to train Sandy, a new employee, to interact with customers at the bank...Prejudice
Paul has been working under a male manager for the last three years. His manager is now being replaced ...Resistance to change
Explanation:
Diversity in language, norms, beliefs, etc. can lead to multiple challenges such as communication or understanding challenges. In the case of the language barrier, this occurs when people speak languages or dialects, and this leads to misunderstandings and communication issues. This occurs in the first case because Alfred cannot communicate successfully with his teammates since he cannot explain his ideas in English.
On the other hand, prejudice occurs when individuals have biased ideas about people based on race, age, preferences, etc. This often leads to discrimination and negative attitudes. This can be seen in the second case because Terri assumes customers will not be comfortable interacting with a new employee just because of her race, which is a biased and unsupported idea.
Finally, resistance to change occurs if individuals perceive changes as negative, and therefore they are afraid or reluctant to new things. This occurs in the third case because Paul does not want to have a female manager, and even considers leaving his job just because there was a change in the manager.
