Chronological text structure is often confused with sequential text structure, and even sometimes it is incorrectly referred to as chronological sequential text structure.
Correct options are A and C.
The "Problem and Solution" and "Chronological" structure is used in the text.
'Problem and Solution' because the author first proposes the problem created by the cables as it allowed them to tap the communications followed by the solution(cutting of cables through the cable ship Telconia).
'Chronological' because the events are portrayed in succession, one after another.
