Which sentences in the passage show how diversity in the workplace is handled correctly?
Jack is a manager in a multinational firm. He is generally known to create teams with people from diverse backgrounds so that they all get to work together. Sometimes these members are from the different parts of the globe. His colleague, Karen, assigns challenging projects only to people who understand English. Jack also motivates all his team members to be tolerant and considerate with people from different cultural backgrounds. However, Karen prefers to work with the younger generation more than people over 40 as older people are generally resistant to changes in the organization.
