In the sentence provided, there is a misplaced modifier.
Explanation:
1. The phrase "Cut in half" is meant to describe the fudge brownie but is incorrectly placed at the beginning of the sentence.
2. As it stands, the modifier is positioned next to "Richard Webber," which suggests that Richard Webber was cut in half. This creates confusion and a misplaced modifier error.
3. To correct this, the sentence could be revised to: "Richard Webber thought the fudge brownie, cut in half, was a more reasonable size."
4. By moving the modifier closer to the noun it is supposed to modify (the fudge brownie), the sentence becomes clearer and eliminates the misplaced modifier issue.
Therefore, the sentence "Cut in half, Richard Webber thought the fudge brownie was a more reasonable size" contains a misplaced modifier.
