Answer. The final sentence: _____________________________________ "<span>The salesperson handed a receipt to each customer that was very long. " ________________________________________________________ </span>→ <span>is the sentence that contains a misplaced modifier. _____________________________________________________ </span>→ Specifically, the placement of the phrase: "that was very long". ______________________________________________________ This is a misplaced modifier, because it is difficult to determine if "very long" modifies either: 1) the actual "receipt" ; or, 2) the "customer(s)" —specifically, "each customer [that happened to be 'very long"]. _______________________________________________________
