Even Though He Teaches History Rather Than English, Mr

Even though he teaches history rather than English, Mr. Stahl wants to support his seventh-grade students in their syntactic development. Which one of the following strategies, although possibly beneficial in other respects, is least likely to promote his students' syntactic development?

A) Teach students a wide variety of sentence structures that they might use.
B) Teach students the differences between similar words (e.g., that vs. which, lie vs. lay) and when to use each one.
C) Engage students in many formal writing activities, and give them regular feedback about punctuation and grammar.
D) Teach students how to take notes more efficiently by capturing ideas in short phrases rather than complete sentences.
