    The various models that are used to approximate the shape of the Earth are called datums. Datums are reference systems that define the origin, orientation, and scale of coordinates used to map the Earth's surface. They take into account the irregularities and variations in the Earth's shape and provide a consistent framework for measuring and representing locations on the Earth's surface. Spheres, coordinates, and ellipsoids are not specific models used to approximate the shape of the Earth, hence they are not the correct answers.

    C. Selecting all census tracts with a per capita income less than $15,000
    Explanation
    The correct answer is "Selecting all census tracts with a per capita income less than $15,000." This is an example of a Select by Attribute query because it involves selecting features (census tracts) based on a specific attribute (per capita income) that meets a certain condition (less than $15,000). This query allows for the extraction of specific data that meets a defined criteria, in this case, selecting census tracts with a lower income level.
