ライティングのオープニングストレステスト

Here is the skeleton for my piece and its central tension: [paste]. Write 4 completely different opening paragraphs for this piece. Each one must use a different entry point: a specific scene, a counterintuitive claim, a named person in a specific moment, and a question the reader cannot immediately answer. None of them should introduce the topic. All of them should drop the reader into the middle of something already in motion. After the four openings, tell me which one creates the most forward momentum and why the others stall.
