Final answer:
The tasks of painting the exterior of a house and the mowing of grass in a residential neighborhood are likely to be delegated, as they are non-personal in nature and do not require the unique skills of the original obligor. Option a and d are the correct answer.
Step-by-step explanation:
In the context of delegations in contract law, certain tasks can indeed be delegated to third parties unless there is a specific provision in the contract that prohibits doing so. Two acts from the options provided that could likely be delegated are:
- Painting the exterior of a house to another house painter.
- The mowing of grass in a residential neighborhood to another landscaper.
These tasks are generally considered non-personal in nature and do not require the unique skills, qualifications, or reputation of the original obligor. Therefore, delegation of such tasks is usually permissible. In contrast, painting a portrait tends to be a personal service that is dependent on the specific skills and style of the artist contracted, and the building of a new courthouse for the city likely involves governmental regulations and standards that would make delegation less straightforward without prior approval.
