Members of every society rely continuously on __________ to make sense of all everyday situations.

The blank in the sentence should be filled with "social norms". So, the complete sentence is: "Members of every society rely continuously on social norms to make sense of all everyday situations."

Here's why:

Step 1: Understand the context. The sentence is talking about something that members of every society rely on to understand everyday situations.

Step 2: Identify the missing component. The blank needs a term that fits this description.

Step 3: Fill in the blank. "Social norms" are rules or expectations that are socially enforced. They represent an understanding of acceptable behavior that is shared by a society or social group. Therefore, people rely on these norms to guide their behavior and understand the behavior of others in everyday situations.
