Answer:
Direct object: pearl
Indirect object: Not any.
Step-by-step explanation:
The sentence "This Indian found one of the biggest pearls ever found" has a direct object, which is the noun "pearl". However, there is no indirect object in this sentence. An indirect object is a noun or pronoun that receives the direct object or tells to whom or for whom the action is done. In this sentence, the subject "This Indian" is the one who found the pearl, and there is no other noun or pronoun to indicate an indirect object. Therefore, the answer is "Not any".
