Which sentence includes a dangling/misplaced modifier?

The first sentence, "Driving in the country, her broke down miles from town," contains a dangling modifier because it suggests that "her" was the one driving in the country. Since "her" appears to be a pronoun referring to a person and does not logically fit with the action of driving, it creates confusion. A clearer construction would replace "her" with a noun that directly connects to the action of driving, such as "car."

In contrast, the other sentences maintain clear connections between the modifiers and the subjects they describe. For instance, "While swimming, she noticed how tired she was" correctly implies that she was the one swimming, maintaining clarity. Similarly, "As he was walking, Stanton noticed change on the ground," and "Hoping for a raise, Liz walked into the chairman's office," both clearly indicate who is performing the action described in the modifiers. Therefore, the best example of a dangling modifier is found in the first sentence.
