\label{Option_Response_Problem_Parts} Each \textbf{Option Response} problem can have three parts: \begin{enumerate} \item The Concept Groups\index{Concept Groups} \item The options for the students to select, by default {}``True'' and {}``False'' \item The hint for the student \end{enumerate} Each \textbf{Concept Group} has some number of foils representing questions which are conceptually related. Option Response Problem Templates are available for 4 and 8 Concept Groups. When the Option Response problem is presented to a student, the LON-CAPA system will randomly select one foil from each Concept Group and present it to the student. In order to receive credit for the problem, the student must select the corresponding option from the drop-down box for each given foil.
