R/exams Moodle schoice question with no points

I would like to create an schoice question in R/exams, via exams2moodle, which includes an answer option without points:

\begin{answerlist}
  \item Zurich is the capital of Switzerland.
  \item Italian is an official language in Switzerland.
  \item The currency in Switzerland is the Euro.
  \item Switzerland is part of the European Union (EU).
  \item No answer (****** this is a zero points answer****)
\end{answerlist}

With these conditions I don't know how to configure \exsolution{0100?}. Thank very much.

PD. Why I need this schoice question? In Moodle when one awswer is ticked in schoice question, imply that this question must be answered. Moodle doesn't allow to untick all answers.

Solution

  • You can add such an option for "abstention" through the eponymous argument for processing the individual Moodle items. For example for an mchoice question (as you list above:

    exams2moodle("switzerland.Rnw", mchoice = list(abstention = "No answer"))

    Analogously, you could add schoice = list(abstention = "Abstention") etc. In either case this adds an answer option that is associated with zero points:

    exams2moodle: abstention
