Answer 2

A sequência dos verbos modais é: can/ can/ should/ has to/ musn't.

Para compreender bem as respostas dessa pergunta é ideal nos relembrarmos do significado/uso dos modal verbs indicados no enunciado da questão.  

• Can: expressa permissão ou possibilidade (poder realizar alguma tarefa). Mais informal que o "may".

• Could: expressa habilidade ou permissão. É utilizado para indicar algo no passado ou então no futuro do pretérito (ele podia escalar ou então você poderia fazer...).

• Must: expressa obrigação.

• Mustn't: o contrário de "must", indica proibição (é a forma contraída de "must not").

• Have to: expressa dever, obrigação (You have to/ você deve).

• May: expressa possibilidade, permissão. Mas formal que o "can".

• Might: expressa uma possibilidade.

• Should: Expressa um conselho.

Com isso, completaremos as frases:
