Here's why:
* Verb: It describes an action or state of being (in this case, being contingent on something else).
* Simple Predicate: The simple predicate is the main verb or verb phrase in a sentence. It's the action or state of being the subject performs.
Example:
* "It depends on the weather."
* Subject: It
* Simple Predicate: depends
