The relative pronoun 'that' can be left out in some cases.
the box (that) he made was made out of wood.
but when a verb has indirect and direct objects, both can be refered by 'that'? in other words, are following constructions possible?
The box that she gave me was in black.(I gave her a box and the box was black. )
The dog that I gave the box was small.(I gave the dog the box and the dog was small. )
and in both cases, those 'that' are able to be left out?
