1. Use of plural nouns and present simple tense: The answer effectively uses plural nouns ("rules," "children," "peers") and the present simple tense ("are," "fosters") to discuss general truths and ongoing actions, which is appropriate for describing general guidelines or behaviors.
2. Use of participial phrases: "Teaching children to share toys and resources" uses a gerund (teaching) to introduce a participial phrase, which serves as the subject of the sentence, adding complexity to the sentence structure.
