The correct answers are A. When the dress code goes into effect; B. How students can voice their opinions and D. Why the principal made this decision
Step-by-step explanation:
In writing, it is important to include ideas that are directly related to the topic and avoid ideas that are not related to the topic or focus. In the case of writing about a new policy of wearing school uniforms, it is important to include details about such as the date this will start, the specific design of the uniform, the reasons for the policy, and the consequences of not following it. Also, because the policy is new it is important to let students know how to communicate their opinion about it.
Therefore, it is important to explain "when the dress code goes into effect"; "why the principal made this decision" and "how students can voice their opinions" as these are directly related to the topic, while others such as what to do with their regular clothes or how clothes are made are not necessary for this topic.
