Read the following passage: "The concept of 'confirmation bias' describes the human tendency to search for, interpret, favor, and recall information in a way that confirms one's pre-existing beliefs or hypotheses. This cognitive bias can lead individuals to selectively gather evidence, interpret ambiguous evidence as supportive, and disproportionately recall information that reinforces their views, while downplaying or ignoring contradictory evidence. For instance, a person who believes a certain political candidate is dishonest might primarily seek out news articles that criticize that candidate, and dismiss any positive coverage as 'fake news.' Confirmation bias is not necessarily intentional; it often operates unconsciously, influencing how we perceive the world and make decisions. It can be particularly problematic in critical thinking, scientific inquiry, and legal proceedings, where objective analysis is paramount. Mitigating confirmation bias requires conscious effort to seek out diverse perspectives and critically evaluate all evidence, regardless of whether it aligns with initial assumptions." Which of the following scenarios best illustrates the concept of confirmation bias as described in the passage?

1. AA juror changing their verdict based on new, contradictory evidence.
2. BA student carefully analyzing both sides of an argument before forming an opinion.
3. CA sports fan only remembering the times their team won, despite a losing season.
4. DA scientist designing an experiment to disprove a widely accepted theory.
