Question

这里暗示的时间是什么时候呀?
Indonesia's Anak Krakatoa volcano lets out a loud roar as it sends up a thick cloud of smoke and flaming red rocks hundreds of meters into the sky.A few hours later,a glowing river of lava and stones flow down the slopes of Mount Anak Krakatoa as the light of the rising sun tries to break through the thick clouds above the mountain.请给出合理的解释,
老师说答案是the night.这又是为什么呀？

Answer 1

哦,因为是 ‘A few hours later,才有rising sun,所以几个小时前当然是晚上.
