Respuesta1
No estoy familiarizado con el paquete de ejercicios pero no encontré nada en la documentación que respalde tener respuestas en la misma línea. Por eso he definido un nuevo comando \subQuestionOnSameLinepara este propósito.
El comando responsable de colocar una subpregunta en una nueva línea es \itemin \@subQuestionHeader. He definido un nuevo comando \@subQuestionHeader@noItemque es básicamente solo la salida de \show\@subQuestionHeadersin \itempero \hspaceen su lugar.
\subQuestionOnSameLinesimplemente reemplaza \@subQuestionHeadercon \@subQuestionHeader@noItemy luego ejecuta el normal \subQuestion.
\@subQuestionHeaderse reinicia al final de la pregunta donde termina el grupo. Hasta entonces todos \subQuestionse comportarán como \subQuestionOnSameLine. Si desea colocar una subpregunta en una nueva línea después de a, \subQuestionOnSameLinepuede usar \subQuestionOnNewLine.
Tenga en cuenta que la primera subpregunta de cada pregunta siempre debe ser normal \subQuestion, nunca \subQuestionOnSameLine.
