For what reason did Hernan Cortes most likely build Mexico city over top of Tenochtilan.

He liked the location. (MY ANSWER)

He wanted to prevent the Aztecs from farming.

He wanted to demonstrate Spanish superiority.

He did no want to spend time looking for another site.

That is the best answer, but it should have been written why he liked the location (strategic location, waterways, roads, central to commerce and population).

Yes, it's an ideal site. That's why the Aztecs chose it in the first place.

And bobpursley is right.

I don't think so.

Im right?

I think Cortes wanted to show up the Aztecs and assert Spanish superiority.

Well, the article Ms. Sue posted would indicate that Cortez wanted to demonstrate Spanish superiority by obliterating the center of the Aztec empire. That may be true. Still, the location was ideal for both the Aztecs and the Spanish for a variety of reasons, some of which bobpursley mentions. I think your answer is the best of the choices given. Go with what you think is best.

If the option said Spanish dominance rather than superiority, I'd say Ms. Sue is right. Maybe,in this context, superiority and dominance are synonymous?

Yes sir and thank yall for helping me.

The most likely reason why Hernan Cortes built Mexico City over top of Tenochtitlan is that he liked the location. To find this answer, one can examine the historical context during the time of Cortes. Cortes defeated the Aztecs and conquered their capital, Tenochtitlan, in 1521. Instead of searching for another site to build a new city, Cortes decided to construct Mexico City on the same location as Tenochtitlan. This choice indicates that he found the location suitable for various reasons, such as its strategic position, access to resources, or potential for economic growth. It is important to note, however, that other factors, such as demonstrating Spanish superiority or preventing the Aztecs from farming, might have also played a role, but there is no conclusive evidence to support these claims.
