Which of the listed sequences primarily indicates a sequence of events structure?

The sequence that primarily indicates a sequence of events structure is marked by terms that clearly guide the reader through a chronological order of occurrences. In this context, "eventually," "next," and "first" serve as explicit markers that delineate the order in which events unfold. "First" establishes the starting point of the sequence, "next" indicates the following step, and "eventually" suggests a progression toward a concluding outcome. This clear linear progression is essential for helping readers understand how events relate to one another over time.

While the other phrases contain transitional words, they do not follow a straightforward chronological sequence to convey events. For example, the terms "during," "while," and "although" suggest simultaneity or contrast rather than indicating a specific order of events. Hence, the clarity and directness of the sequencing in the correct choice make it the best representation of a sequence of events structure.
