Final answer:
The corrected clause 'Mr. Oroc cultivates this farm' is an independent clause because it has a subject and a verb and can stand alone as a complete sentence with a complete thought.
Step-by-step explanation:
The question "Who cultivates this farm is Mr. Oroc" involves a clause, which can be either independent or dependent. To determine the type of clause, we need to check if it can stand alone as a sentence. In this case, if we correct the clause to 'Mr. Oroc cultivates this farm,' it can be a sentence by itself, making it an independent clause.
An independent clause contains a subject and a verb and expresses a complete thought. For example, 'Mr. Oroc cultivates this farm,' has 'Mr. Oroc' as the subject and 'cultivates' as the verb, and it does not need additional information to be understood.
On the other hand, a dependent clause (or subordinate clause) is a clause that cannot stand alone as a complete sentence because it does not express a complete thought. An example of a dependent clause would be 'because Mr. Oroc is away', which on its own does not form a complete idea.
