Parameters
string$answertextThe answer text
double$pointsThe points for selecting the answer (even negative points can be used)
integer$orderA possible display order of the answer
integer$solution_orderAn unique integer value representing the correct order of that answer in the solution of a question
integer$depthrepresents the depth of that answer public
