\label{Authoring_NumericalResponse} \textbf{stringresponse} implements a string answer. An internal \textbf{textline} tag (see \textbf{\ref{textline}}) is necessary for the student's response to go in. It can check the string for either case or order. Possible attributes are: \begin{itemize} \item \textbf{answer}\index{answer}: required. Specifies the correct answer, either a perl list or scalar. \item \textbf{type}\index{type}: optional. Specifies how the string is checked (like the CAPA styles). Possible values are: \begin{itemize} \item \textbf{cs}\index{cs}: \textbf{c}ase \textbf{s}ensitive, order important. \item \textbf{ci}\index{ci}: \textbf{c}ase \textbf{i}nsensitive, order important. \item \textbf{mc}\index{mc}: case insensitive, order unimportant. The mnemonic for this option is {}``\textbf{m}ultiple \textbf{c}hoice'', which is how it was used in CAPA: To allow the user to specify choices from a multiple choices problem, as in {}``adce'', meaning parts a, d, c, and e are true. Order didn't matter in such a problem. In LON-CAPA, using \textbf{optionresponse} with True and False foils would be preferable, but this will remain supported for easier CAPA to LON-CAPA conversion. \end{itemize} \end{itemize}
