In line 3 which is the correct pronoun agreement for balloons they hate how the balloons have to be completely full or it won’t float

The correct pronoun agreement for "balloons they hate" would be "they" since it refers back to the plural subject "balloons."

In the sentence, "they hate how the balloons have to be completely full or it won't float," the correct pronoun agreement for "balloons" is "they."

To determine the correct pronoun agreement in this sentence, we need to look at the antecedent (the word that the pronoun refers to). In this case, the antecedent is "balloons."

The pronoun that agrees with "balloons" should be plural to maintain agreement. Therefore, the correct pronoun is "they."

Let's break down the sentence to see how to arrive at the answer:

- "Balloons they hate" -> Here, "balloons" is the noun being referred to, and it is plural. Therefore, we use the plural pronoun "they."
- "How the balloons have to be completely full or it won't float." -> Here, "it" is referring to the singular word "balloon." So, historically, this would be the part where the agreement issue arises in the sentence. However, since the sentence already refers to "balloons" and uses the plural pronoun "they," the reference to the singular "balloon" with "it" is understood to be a general reference rather than a specific one.

Thus, we have determined that the correct pronoun agreement is "they" to match the plural noun "balloons."
