_________________ is useful when you need to change how the data source is configured on a sheet-by-sheet basis, and when you want to combine databases that don't allow relationships or joins
Answer(s): D
Data blending is performed on a sheet-by-sheet basis and is established when a field from a second data source is used in the view. To create a blend in a workbook already connected to at least two data sources, bring a field from one data source to the sheet--it becomes the primary data source. Switch to the other data source and use a field on the same sheet--it becomes a secondary data source. An orange linking icon will appear in the data pane, indicating which field(s) are being used to blend the data sources.According to the official Tableau Documentation:To read more about Data Blending, click on THIS link.

How does Tableau know at which level to aggregate values?
In Tableau, you can aggregate measures or dimensions, though it is more common to aggregate measures. Whenever you add a measure to your view, an aggregation is applied to that measure by default. The type of aggregation applied varies depending on the context of the view.When you add a measure to the view, Tableau automatically aggregates its values. Sum, average, and median are common aggregations; for a complete list, see List of Predefined Aggregations in Tableau. The current aggregation appears as part of the measure's name in the view. For example, Sales becomes SUM(Sales). Every measure has a default aggregation which is set by Tableau when you connect to a data source. You can view or change the default aggregation for a measure--see Set the Default Aggregation for a Measure.You can change the aggregation for a measure in the view from its context menu:
