Não estou familiarizado com o pacote de exercícios mas não encontrei nada na documentação que ele suporte para ter respostas na mesma linha. Portanto defini um novo comando \subQuestionOnSameLinepara este propósito.
O comando responsável por colocar uma subquestão em uma nova linha é o \itemin \@subQuestionHeader. Eu defini um novo comando \@subQuestionHeader@noItemque é basicamente apenas a saída \show\@subQuestionHeadersem o \itemmas a \hspace.
\subQuestionOnSameLinesimplesmente substitui \@subQuestionHeaderpor \@subQuestionHeader@noIteme depois executa o normal \subQuestion.
\@subQuestionHeaderé redefinido no final da pergunta onde o grupo termina. Até então, todos \subQuestionse comportarão como \subQuestionOnSameLine. Se você quiser colocar uma subquestão em uma nova linha depois de a \subQuestionOnSameLinevocê pode usar \subQuestionOnNewLine.
Observe que a primeira subquestão de cada pergunta deve ser sempre normal \subQuestion, nunca a \subQuestionOnSameLine.
