How is "She will attend the party" transformed when changing "will" to "might"?

The transformation of "She will attend the party" to "She might attend the party" appropriately captures the change in modality brought about by substituting "will" with "might."

In the original statement, "will" indicates a strong certainty about the future event, suggesting that attendance is definite. In contrast, using "might" introduces uncertainty or possibility, indicating that attendance is not guaranteed and that there is a chance she may or may not attend.

The selected answer directly uses the verb "might" as a modal verb, reflecting this shift in certainty while maintaining the original meaning of the sentence regarding the event of attending the party.

Other choices, while including elements of possibility or certainty, do not accurately reflect the transformation implied by changing "will" to "might." For instance, stating "She will probably attend the party" still suggests a degree of certainty, which contradicts the intended meaning introduced by "might." Similarly, the original phrase remains unchanged in one of the options, and the alternative phrasing in another includes a different grammatical structure that implies a different meaning related to attendance. None of these options encapsulates the correct transformation as effectively as the chosen one.
