Which question might historian as to investigate what happened? need asap

Where did the sinking take place?

Explanation:

In trying to figure out what happens you need to evaluate the past events. Where this happened is important to know what happened.  

by 1880, germany had more rail lines than great britain and russia.

        i'm fairly sure that the correct answers are 2 and 3.

        i used both my knowledge of world history and the process of elimination to obtain these answers. option 1 cannot be a possible selection because the mandate of heaven belongs to ancient chinese philosophical belief. option 4 sounds like it would benefit the region than detriment it. however, both 2 and 3 explain a potential reason for what could have contributed to the fall of the roman empire.

      hope this ! if i were you, i'd get a second opinion, because i haven't taken this course for a year. best of luck!
