—Catherine,  I have cleaned the room for you.—Thanks. You_______ it.  I could manage it myself.

I’m fond of my sister, but she has a serious shortcoming. She _______ be really stubborn.

The police still haven’t found the lost child, but they’re doing all they             .

______ I see your ID card, sir? We have to check your information.

—Where _____ Mary have put the empty bottles? — She _____ them away. They must be somewhere.
