Hi,
in the first question, clearly C is the starter after A. then we see a link between E and D, where E comes before D ,as the trauma is defined in E.
thus, the answer is C) CBED.
In the next question,
statement E continues the story in statement A.
there is a BC pair, where B defines the move and C is the concluding the move.
thus, the answer is EDBC.
