1.the aztec copied their city plan from maya and olmec cities.
2.the size of the temples in the city is evidence of a unique religion.

I believe the answer is: 3. The canals and temples in the city show advanced engineering skills.

The site shows that the Aztec civilization had developed a very advanced irrigation system that utilize different elevation to obtain water for their agricultural field. Their system was later adopted by the spanish empire who invaded their territory.

on 6 november american voters will elect members of the house of representatives and the senate, which together are called congress.

both houses of congress are currently controlled by the republican party, which backs president donald trump.

the democrats think they can win control of the house of representatives this year by winning a majority of seats.

doing so would let them block or delay the president’s plans by refusing to enact them.

all 435 seats in the house of representatives are up for election.

if the democrats want to take control of the house by having the most seats, they’re going to have to claim at least 23 from the republicans.
