Which of the following are public use bonds used for?

Public use bonds are specifically designed to finance projects that serve the community, such as highways, schools, parks, hospitals, and other infrastructure that benefit the general public. These bonds allow local and state governments to raise funds through borrowing, which can then be invested in essential public services and facilities.

The nature of public use bonds is that they are supported by the revenue generated from these projects or by taxation, and they encompass a range of public needs that are crucial to enhancing the quality of life for residents. By financing projects that directly improve public services and infrastructure, public use bonds play a vital role in community development and economic growth.

This focus on serving public interests is what distinguishes public use bonds from the other choices. Private investments, personal loans, and funding for private commercial projects do not align with the intended public benefit associated with these types of bonds. Similarly, retirement funds are related to employee compensation and benefits rather than infrastructure or public service funding. Therefore, the key characteristic of public use bonds is their objective to support public purposes like highways and schools, making that the correct choice.
