3. It can be inferred from the passage that if the S waves from an earthquake arrive at a given location long after the P waves, which of the following must be true?
(A) The earthquake was a deep event.
(C) The earthquake focus was distant.

Because P and S waves travel at different but fairly constant speeds, the interval between their arrivals increases in proportion to the distance from the earthquake focus, or rupture point.
-->the interval 和the distance from the earthquake focus成正比 & the earthquake focus = rupture point

支持C
