In which Modeler palette would you find nodes for importing data?

The correct answer is found in the "Sources" palette, which is specifically designed to include nodes for importing data. This palette contains various options that allow users to bring data into the analysis environment from different sources, such as databases, flat files, and other data repositories. The nodes here facilitate the connection to the sources and streamline the process of extracting the necessary data for further modeling and analytics.

The "Modeling" palette is typically focused on nodes used for creating and applying predictive models rather than on data importation. The "Import" palette does not exist in this context, as the functionality for importing data is consolidated into the Sources palette. The "Record Ops" palette is primarily concerned with data transformation and manipulation once the data has already been imported, rather than the initial step of data importation.
