What does the word "always" indicate in terms of event occurrence?

The word "always" indicates that an event occurs consistently without exception. This implies a fixed or regular pattern in the timing of its occurrence. In the context of the provided options, "chronological" relates to the order of events in time. While "always" implies consistency rather than a sequence, it aligns most closely with the notion of events happening in a specific and predictable manner over time, which can be interpreted as chronological order.

In contrast, the terms "sequential," "occasional," and "irregular" do not fit with the definition of "always." "Sequential" suggests an order based on one event following another, while "occasional" indicates something that happens infrequently or at irregular intervals. "Irregular" describes events that do not occur in a consistent manner. Therefore, the interpretation of "always" associating with "chronological" fits best in the context that it describes predictable occurrences.
