DIVIDE([Total Sales], [Total Sales]), although it sounds technically credible, it does not align with how DAX functions propagate context in this scenario.

CALCULATE([Total Sales] / ALL(Products)), although it sounds technically credible, it does not align with how DAX functions propagate context in this scenario.

[Total Sales] / SUM(Sales[Amount]), however, this wording confuses row context, filter context, or evaluation timing and therefore misses the exact DAX behavior being tested.

A syntax-level statement that appears valid but actually describes iterator usage in a context where scalar evaluation is required
