What is Simple subject?
A single word or pronoun joined to a verb is referred to as a simple subject. In most cases, the simple subject comes before the verb in a sentence. While modifications may be present in the entire subject.
What is Simple Predicate?
A simple predicate is the main verb or verb phrase that characterizes the action of the subject of each sentence. The only part that contributes to being a simple predicate is the leading verb or verb phrase. There are no modifiers in the sentence. 
In this sentence given in the question "Luckily Dad had bought a battery-powered radio after the last storm.", but since "<u>had bought</u>" is a verb, it works as a simple predicate. Also, since the word "<u>Dad</u> " is a noun or pronoun, it acts as a simple subject.
