Verified step by step guidance

1. Understand the bystander effect: it is a social psychological phenomenon where individuals are less likely to help a victim when other people are present, often due to diffusion of responsibility.
2. Analyze each scenario by considering the number of bystanders and the social context to determine the likelihood of the bystander effect occurring.
3. Recognize that in crowded or busy environments (like a shopping mall, busy street, or crowded subway), the bystander effect is more likely because people assume others will intervene.
4. Note that in the scenario with only one other person present in a quiet park, the bystander effect is least likely because the responsibility to help is clear and not diffused among many people.
5. Conclude that the scenario where a man falls off his bike in a quiet park with only one other person who immediately helps is least likely to result in the bystander effect.
