"I'm (do not) really not understand what the situation (is) for 2 verbs that can be used in a 1 sentence .
As (in) the (example) below example I found form (from) a book :
Violet made a face when all she saw inside was a funny-looking piece of paper.
( Violet opened the present and found a piece of paper inside)
Why the 'saw' & 'was' appeared in the same sentence as the verbs ?
Possible answer: Ellipsis - there is part of the sentence removed probably for being self-evident. The full sentence should read:
Violet made a face when all (that) she saw inside was a funny-looking piece of paper.
