What type of interaction is exemplified when Eduardo calls a colleague six times a year for advice?

The correct answer is based on the nature of the interaction described. When Eduardo calls a colleague six times a year for advice, it demonstrates a repeatable interaction. This is because the frequency and consistency of the calls imply that there is an established pattern or routine in these communications. The relationship is not just a one-time occurrence; instead, it signifies an ongoing exchange of support and knowledge, which is characteristic of repeatable interactions.

In contrast, one-time interactions represent singular events that do not recur. Irregular interactions indicate unpredictable or inconsistent communication patterns, which differs from the consistent nature of Eduardo's calls. Casual interactions might suggest a less formal or significant form of communication, which might not capture the purpose or intent behind Eduardo's calls for advice, further affirming that the repeated nature of these calls is what aligns most closely with the understanding of repeatable interactions.
