What can be inferred about the physics of Earthquake Early Warning (EEW) systems?
- A They rely on the fact that non-destructive waves arrive before destructive ones.
- B They can precisely predict the exact date and time of a future rupture.
- C They focus on slowing down S-waves through base isolation.
- D They only function after the destructive shear waves have been detected.

可以推論 EEW 系統運作的基礎是 P 波（壓縮波，非破壞性）傳播速度比 S 波（剪力波，具破壞性）快，利用此時間差在強震抵達前發布警報。
