Questions: In which of the following sentences is the modifier placed correctly? The student started the debate in class with the red hair. The student started the debate with the red hair in class. The student with the red hair started the debate in class.

The answer is "The student with the red hair started the debate in class."

In this sentence, the modifier "with the red hair" is placed incorrectly. It seems to suggest that the debate itself has red hair, which is illogical.

Here, the placement of "with the red hair" is ambiguous. It could imply that the debate has red hair or that the student started the debate while having red hair in class, which is confusing.

This sentence correctly places the modifier "with the red hair" immediately after "The student," clearly indicating that it is the student who has red hair. This placement avoids ambiguity and makes the sentence clear and logical.
