What is true when a field update is set to re-evaluate the workflow rule?

1. In a batch update, workflow is only retriggered on the entities where there is a change.
2. Only workflow rules on the same object as the initial field update will be re-evaluated and triggered.
3. Only workflow rules that didn’t fire before will be retriggered.
4. Cascade of workflow rule re-evaluation and triggering can happen up to ten times after the initial field update that started it.
5. Any workflow rules whose criteria are met as a result of the field update will be ignored.
