You're very welcome.

In the given sentence, "ninety percent of the audience had voted with their feet," there is a pronoun agreement error. The pronoun "their" does not agree with the noun it is referring to, which is "ninety percent." To correct the pronoun agreement, we need to use the correct pronoun form that matches the noun.

To determine the correct pronoun agreement, we need to identify the number or quantity that the noun represents. In this case, "ninety percent" is a singular noun because it refers to a specific quantity. Therefore, we should use the singular pronoun "its" instead of the plural pronoun "their."

Corrected sentence: By the final curtain, ninety percent of the audience had voted with its feet.

To avoid pronoun agreement errors, it is important to ensure that the pronoun used matches the number of the noun it refers to. In this case, since the noun "ninety percent" is singular, we use the singular pronoun "its" to maintain agreement.
