What structural mistake appears in the sentence about Nicole's plans?

The sentence about Nicole's plans may contain an overuse of commas in independent clauses, making it difficult to follow the flow and clarity of the sentence. When independent clauses are combined, they typically require a conjunction or a semicolon for clarity, rather than being overly punctuated with commas. This can create confusion for the reader as the sentence may appear choppy or fragmented due to excessive punctuation.

In contrast, effective punctuation helps to clearly convey the relationship between ideas. Proper use of commas generally applies to lists or to separate clauses when necessary, but excessive use can hinder understanding. Therefore, recognizing and correcting the over-punctuation in independent clauses enhances the readability and coherence of the sentence about Nicole's plans.
