Question

multiple-choice question
what was the covered causeway filled with to help move the blocks up the side of the pyramid?
cattle
gravel
slaves
water

Explanation:

To determine what filled the covered causeway to move pyramid blocks, we analyze the options. Cattle (livestock) and slaves (people) aren’t materials for reducing friction/moving blocks. Gravel is possible, but historical evidence and engineering logic suggest gravel (small stones) was used to create a smooth, rolling surface for transporting heavy blocks up the pyramid’s side. Water wouldn’t aid in rolling blocks, and gravel’s granular nature helps with movement.

Answer:

B. gravel
