Answer 1

Resposta:

1. Paul CAN'T be at home; he always works until 9 P.M

2. My sister MAY come back from London tonight, but I'm not sure.

3. Mary MUST have forgotten our appointment. Why isn't she here?

4. You SHOULDN'T have told us about Sue's divorce. We made such insensitive comments on her husband.

5. I'm afraid I CAN'T go out tonight. I have to work late.

6. Most children MUST wear school uniforms in private school.

7. Someone's knocking at the door. It MUST be James. He said he'd come around today.

Faltou informação na opção 7, mas eu tenho total convicção de que há a opção de "must" entre elas. Nessa poderia ser "might" também. Mas "must" se comporta melhor nessa oração. Bons estudos. <3
