Question

20 POINTS, PLEASE HELP.

Answer 1

I would go with answer choice C. because b. and d. don't apply to main idea they are just extra info and a. says its an accomplishment. ok that has nothing to do with the main idea that it required a large workforce

Answer 2

Answer:

Experts today estimate that 20,000-30,000 laborers worked on the pyramid at any one time.  

Explanation:

The main idea about the enormous labor force required to build the pyramid is appropriately supported by the number of workers that specialists believe were employed to construct it.

The rest of the choices are incorrect because they do not provide evidence for or make reference to the number of personnel demanded to erect the pyramid. Option one is too general, alternative three mentions shape ramps not included in the main idea, and choice four details how work crews were arranged.
