What grammatical change is needed in the sentence about Margot's decision?

To determine the necessary grammatical change regarding Margot's decision, we need to focus on the consistency of the pronoun used in relation to the noun it represents. If the sentence discusses three extra credit questions, the pronoun that refers back to them should be plural to remain consistent with the subject being discussed.

In this context, changing "ignored it" to "ignored them" aligns the pronoun with the plural noun "questions." Using "them" correctly indicates that Margot is referring back to multiple extra credit questions, maintaining grammatical coherence and clarity in the sentence.

This adjustment enhances the readability and ensures that the sentence accurately reflects the number of items being discussed, affirming the reader's understanding of Margot's action regarding the extra credit opportunities.
