It (not be) my dog , he was with me all day. It(be)my brother's
5. The president (unveil) the statue , but he is ill so his wife is doing instead .
6. I didn't recognize the voice at the other end of the line. It(be) my elder sister : she is often at home at that time. It (not be) my younger sister,as she is abroad.
