Which of the following are examples that make up a nuisance per se?

The correct choice of slaughterhouse and mulch pile as examples of a nuisance per se is grounded in the nature of these activities as inherently harmful or disruptive to the surrounding community. A nuisance per se refers to an activity or condition that is considered a nuisance in and of itself, regardless of the specific circumstances or the area in which it is located.

In this instance, a slaughterhouse typically involves processes that can produce unpleasant odors, attract pests, and create noise, which negatively affects the quality of life for nearby residents and can lead to health concerns. Similarly, a mulch pile, especially if poorly managed, can contribute to odors, attract insects, and even pose a fire risk. These characteristics make them distinctly problematic without needing to evaluate the context or external factors.

Other options presented may involve activities that can either be necessary or beneficial depending on their context or implementation, and they do not inherently create the same level of disruption or harm. For instance, an office building and a playground are often seen as positive parts of a community, contributing to social and economic activity. Likewise, while construction sites and smoke stacks can produce nuisances during operation, they may not do so to the same degree as the inherent nature of a slaughterhouse or a mulch pile.
