Question

)What conclusion did historians draw about the Incas after the discovery of Machu Picchu?

The Incas were skilled engineers.

The Incas were strongly influenced by the Aztecs.

The Incas were strongly influenced by the Mayas.

The Incas had no organized system of communication.

Answer 1

I'd say that the conclusion historians point to about Machu Picchu is that the Incans were very good builders -- skilled engineers.

There's no evidence that the Mayans or the Aztecs influenced them in any way, and the Incans did have an organized system of communication using knots of tied rope to keep track of everything from inventory to history. Unfortunately, no one today knows how to interpret these knots.

Answer 2

The correct answer is - The Incas were skilled engineers.
