Demonstração do violinista:http://jsfiddle.net/natmit/7Du6N/

Eu tenho puxado meu cabelo, então qualquer ajuda dos gênios JavaScript / Jquery por aí é muito apreciada ... Eu já entrei em contato com o autor deste código e ele não respondeu.

Preciso de ajuda para fazer o teste, faça o seguinte:

Após o usuário clicar na opção, mostre a explicação imediatamente sem clicar em "Verificar resposta".

Não quero o botão "Verificar resposta". O botão enviar deve ficar oculto até o usuário clicar na opção e, em seguida, ele deve aparecer com o rótulo "Próxima pergunta" e, ao clicar, passar para a próxima pergunta no questionário.

Mova a explicação para exibir abaixo das opções de resposta.

Na página de resultados, eu preciso de uma maneira de exibir uma imagem se eles tiverem de 1 a 5 corretos e uma imagem diferente se eles tiverem de 6 a 8 corretos (supondo que haja 8 perguntas no total).

Agradecemos antecipadamente, N
