Final answer:
The misplaced modifier 'Running through the park' was corrected by attaching it to the intended subject, resulting in the sentence 'Running through the park, I thought the trees looked beautiful'. This clarifies that it was the speaker, and not the trees, who was running.
Step-by-step explanation:
Modifier in the English grammar, is a word or phrase which adds meaning to the sentence. To fix the misplaced modifier in the sentence, we should place the modifier next to the noun it is supposed to modify. The phrase 'Running through the park' should be placed in front of the subject who is actually doing the running. The corrected sentence would be: Running through the park, I thought the trees looked beautiful.
This correction ensures that the modifier clearly refers to the subject, which is 'I' in this case. The original sentence made it seem as though the trees were running, which is not logical.
