Issues:
* Missing Verb: "It going to be" is not a complete verb phrase. It needs a helping verb like "is" or "will" to make sense.
* Ambiguous Pronoun: "Who" is a pronoun that needs a clear antecedent (the noun it refers to). In this case, it's unclear who "who" refers to.
Possible Corrections and Subject/Object Analysis:
Let's break down some possible corrections and analyze their subject and object:
1. "Who is going to be it?"
* Subject: "Who" (the pronoun)
* Object: "it" (the pronoun)
2. "Who is going to be the winner?"
* Subject: "Who" (the pronoun)
* Object: "the winner" (the noun phrase)
3. "Who is going to be there?"
* Subject: "Who" (the pronoun)
* Object: "there" (adverb, not an object in this case)
Explanation:
In these examples, we have a complete verb phrase (e.g., "is going to be") and clarified the pronoun "who" by providing a clear antecedent (e.g., "winner" or "there").
Important Note: Sentences need a clear subject (the doer of the action) and a verb (the action). Without these, the sentence lacks meaning and grammatical correctness.
