No ideas on any of them?

Nominative case: I,he,she,we,they
Objective case: me,him,her,us,them

So,

#3 she
#6 them
#7 our -- why? "our" is an adjective

can you get the others?

1. The first girl chosen was she.

2. The treasure hunters, he and she, were interviewed by reporters.
3. Mike and she are leaving tomorrow.
4. Lebron and he have been inseparable since third grade.
5. The strongest swimmers were Michael and he.
6. Watching them he realized how talented they were.
7. I look forward to our planning a party.
8. Tony, Andy, and I are going to the lake this weekend.

To determine the correct pronoun for each sentence, we need to identify whether the pronoun should be subjective (he, she, they, we, I) or objective (him, her, them, us, me) based on its role in the sentence.

1. The first girl chosen was (she, her).
To determine the correct pronoun, we need to identify the subject of the sentence. In this case, the subject is "The first girl chosen." Since the pronoun is taking the place of the subject (in place of "The first girl chosen"), we use the subjective pronoun. Therefore, the correct pronoun is "she."

2. He treasure hunters, (he and her, he and she), were interviewed by reporters.
The pronoun in question is referring to multiple people (treasure hunters). Since it refers to more than one person, we need to use the subjective pronoun that represents a combination of genders. Therefore, the correct pronoun is "they."

3. Mike and (she, her) are leaving tomorrow.
The pronoun in question is referring to the subject of the sentence, "Mike and (she, her)." Again, since the pronoun is taking the place of the subject, we use the subjective pronoun. Therefore, the correct pronoun is "she."

4. LeBron and (he, him) have been inseparable since third grade.
The pronoun in question is referring to the subject of the sentence, "LeBron and (he, him)." Similar to the previous example, since the pronoun is taking the place of the subject, we use the subjective pronoun. Therefore, the correct pronoun is "he."

5. The strongest swimmers were Michael and (he, him).
The pronoun in question is referring to the person mentioned in the sentence, "Michael and (he, him)." In this case, the pronoun is taking the place of the object, so we use the objective pronoun. Therefore, the correct pronoun is "him."

6. Watching (they, them) he realized how talented they were.
The pronoun in question is referring to the people described as "they" in the sentence. Since the pronoun is taking the place of the subject of the sentence, we use the subjective pronoun. Therefore, the correct pronoun is "they."

7. I look forward to (us, our) planning a party.
The pronoun in question is referring to the person or people mentioned in the sentence. Since it is part of a possessive statement (such as "our," "his," "her," etc.), we use the possessive pronoun. Therefore, the correct pronoun is "our."

8. Tony, Andy, and (I, me) are going to the lake this weekend.
The pronoun in question is referring to the person mentioned in the sentence as part of a list of names ("Tony, Andy, and (I, me)"). Since it is the subject of the sentence, we use the subjective pronoun. Therefore, the correct pronoun is "I."
