Answer:
No
Step-by-step explanation:
A misplaced modifier is a word, or group of words where the modifier in a sentence is improperly placed away from the word it modifies. This causes the sentence to sound ridiculous and sometimes, downright illogical.
Therefore, the sentence below, "lowa is one of the greatest corn-producing states in the United State" does not have a misplaced modifier because the modifier is correctly placed next to the word it modifies.
