Answer:Alex registers the chaotic energy of the crowd and fears for the safety of his family.
Explanation:
In this excerpt, Alex is not experiencing a flashback because the extract states "as if it had already happened", showing it has not already happened. The best answer is 'Alex recognises the significance of the moment and wants to share it with his family'. His handset is not malfunctioning, because he has "no trouble locating his wife's handset", and the description of the crowd does not lead the reader to believe there is a chaotic energy.
