Hi, these are sentences from another forum, which have created a lengthy debate. Some of them are difficult to determine if they are simple or complex clauses; that is, what types of clauses exist in these sentences.
-----------------------------------------------------------------------------------------------------------------------------------------------
1.There was a welter of signs at the corner, each pointing in a different direction.
2. We watched Tim glut himself on pizza.
3. The butcher sold the entrails of the cow at a lower price than the other parts.
4. Seeing the barrow, the women knew they had found the grave of her grandfather.

Please identify the independent clauses and dependent clauses that exist in these clauses.

Thanks in advance.
