True or False: A teacher may need more than one lesson to teach a new item of grammar.

The correct answer is true because teaching a new item of grammar often requires more than one lesson to ensure effective understanding and retention by students. Grammar concepts can be complex and may not be immediately grasped in a single session. A teacher may introduce the grammar point, provide examples, and engage students in practice during the first lesson. Follow-up lessons can then reinforce the new concept by incorporating additional practice, contextual use, and integration with other language skills, such as speaking or writing. This gradual approach allows students to become comfortable using the grammar point in various contexts, solidifying their understanding and ability to apply it correctly.

The other options suggest that one lesson may suffice or limit the need for additional lessons based on class levels or specific student needs. However, language acquisition often benefits from repetition and varied exposure, which aligns with the rationale for having multiple lessons to teach complex structures like grammar.
