Question

how is building a skyscraper today simular to and different from the building of the pyramids

Answer 1

I would think you could put together some things that are relatively obvious. For example, do you think moving steel beams to the top of a skyscraper might be similar to moving boulders/rocks to the top of a pyramid? And do you think that the motorized hoists available to do that today are different than what was available at the time the pyramids were built? Put some thought into it and go from here.
