Answer:
Simple predicate - "delivered packages and mail"
Simple subject - "Frank", "School".
Step-by-step explanation:
The sentence “Frank delivered packages and mail to the school every day”. This sentence contains both simple predicate and simple subject. The simple predicate here is ‘delivered packages and mail’. Simple subject here is ‘frank’ and ‘school’. This is because Frank and school is an example of simple noun and it forms the simple subject. The simple predicate here is delivered packages and mail because it does not gives the complete information of the entire scenario.
