If a community experiences increased noise pollution from a local concert venue, which of the following is the primary underlying cause of the negative externality observed?

The primary underlying cause of the negative externality from increased noise pollution at a concert venue is that the venue's activities affect people who are not directly involved with it. When concerts happen, the loud music and noise can disturb nearby residents, making it hard for them to enjoy their homes or sleep. This situation shows how the concert venue's actions create a cost for the community, even though the venue itself benefits from hosting events. For example, if a family living near the venue cannot sleep because of the noise, they are experiencing a negative impact that they did not choose. Therefore, the concert venue's enjoyment comes at a cost to those living around it, illustrating how one group's activities can negatively affect another group.
