Task 1 Read the text carefully.

The pyramid blocks were hewn from quarries using stone and copper tools. The blocks were transported to the pyramid site from remote quarries using barges, and from local quarries using wooden sleds. The Egyptians did not use the wheel during the Pyramid Age, an invention that would have been of limited use on softer ground under heavy loads. The sleds were dragged manually, sometimes with the help of beasts of burden, over smoothed roads. Some of the existing pathways were equipped with transverse wooden beams to lend support to the sled. A lubricant may have been poured upon the road to reduce friction.

Egyptians successfully completed the most massive building projects in all of history. There is nothing magical or supernatural in the means by which they achieved their goals, as is commonly thought. By all indications, they retained their knowledge of construction throughout their history, but they were limited after the Fourth Dynasty not by the lack of technology but rather by the lack of the abundant resources that were previously available. More than two thousand years later, the Romans would move huge stones, some weighing nearly 1,000 tons, using similar techniques at Baalbek.
