Question

complete the sentence with the better correlative conjunctions.
beth plans to wear ____ her new ankle boots ____ her leather sandals to the festivities on saturday.
either...or
not only...but also

Explanation:

The sentence presents two mutually exclusive footwear options for Beth to wear to one event, so a correlative conjunction pair indicating a choice is needed. "either...or" expresses a choice between two alternatives, while "not only...but also" is used to add two related items that both apply, which does not fit the context of choosing one outfit for a single event.

Answer:

either . . . or
