Final answer:
The sentence contains two main clauses, one independent and one dependent.
Step-by-step explanation:
The sentence "I have knowledge that will benefit you if you will hear what I have to say" can be divided into two main clauses.
- The first main clause is "I have knowledge that will benefit you." The subject is "I", marked in yellow, and the verb is "have", marked in red. This is an independent clause because it can stand alone as a complete sentence.
- The second main clause is "if you will hear what I have to say." The subject is "you", marked in yellow, and the verb is "will hear", marked in red. This is a dependent clause because it begins with the subordinating conjunction "if".
