Answer:
Luisa finds and corrects an error in ___punctuation_______.
Step-by-step explanation:
a) The paragraph omitted a comma punctuation mark after the word "campfire." When Luisa puts this comma after "campfire," the sentence becomes grammatically correct.
So the error that Luisa finds and corrects in the passage is the omission of comma punctuation. A comma punctuation mark gives a short break in a sentence. Full stop gives a long break.
