In the sentence about holiday plans, what needs adjustment?

The choice regarding the adjustment of "neither...or" is based on the grammatical structure that requires the correct use of conjunctions. The standard construction for this phrase is "neither...nor," which is used to connect two negative alternatives. When "neither" is used, it should always be paired with "nor" to maintain proper grammatical form and coherence.

This adjustment can significantly enhance the readability and precision of the sentence, ensuring that it clearly communicates the intent without ambiguity. Proper use of such conjunctions is essential in writing to establish clear relationships between ideas and maintain standard conventions of English grammar.

Thus, the need for using "nor" instead of "or" reflects a fundamental grammatical principle that governs the structure of negative clauses, which is essential in formal writing.
