What procedure is used to confirm that sugar has not settled in the nozzle of the tea urn?

The correct procedure to confirm that sugar has not settled in the nozzle of the tea urn is to draw a cup of tea and pour it back into the top. This method ensures that any sugar that may have settled in the nozzle is mixed back into the tea. By drawing a cup of tea, you are able to not only check the flow and consistency of the beverage but also ensure that the sugar is adequately dissolved and distributed throughout the urn. Pouring it back into the top further facilitates the remixing process, helping to prevent any inconsistency in sweetness in the servings.

Other methods like shaking the urn, visually inspecting the nozzle, or checking the sugar level may not be as effective in confirming the even distribution of sugar within the tea. Shaking the urn may not ensure all sugar is dissolved or mixed properly, and a visual inspection may not reveal hidden issues. Checking the sugar level only indicates how much sugar is present but doesn't confirm its distribution within the tea. Thus, pouring the drawn tea back into the urn is the most reliable method for confirming that sugar is not settled in the nozzle.
