Final answer:
The given sentence is written false because of an error in punctuation.
Step-by-step explanation:
The given sentence is written false. There is an error in punctuation as there is a semicolon before the coordinating conjunction 'and', which is incorrect. Semicolons are used to separate two independent clauses in a sentence, but in this case, 'and' is connecting two independent clauses, so a semicolon is not needed. The correct version of the sentence would be: He ran to the store before the storm, and they had plenty of milk and eggs.
