Final answer:
The statement 'Once credibility is lost, it is easy to regain' is false.
Step-by-step explanation:
The statement 'Once credibility is lost, it is easy to regain' is false. Credibility refers to the trustworthiness and believability of a person or source. When credibility is lost, it can be difficult to regain because trust has been broken. Examples of individuals who have lost credibility, like Brian Williams of NBC, had to face investigations, apologies, and even removal from their positions. Therefore, regaining credibility requires consistent honesty, accountability, and rebuilding trust over time.
