I think 3rd choice is the correct answer
It covers an area of 8,511,965 sq km<span> (3,286,488 sq mi), extending 4,395 km (2,731 mi) </span><span>N </span><span>– </span><span>S </span><span>and 4,320 km (2,684 mi) </span><span>E </span><span>– </span><span>W </span>.<span>
</span>
The answer is definitely false. Hope this helps!!! Please 5 star and thank me!!!
The only change I know of was the silk road, where they had to build roads and clear forests so that traders could go through. I don't think any other geography changed during that era.
