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.

Write down True, False or Doesn’t say. Use the keys.

1 - The wheel was invented during the Pyramid Age, even though it was not used.

2 - Sleds were dragged by animals not humans.

3 - It is possible that Ancient Egyptians could have lubricated their roads to aid transportation.

4 - The building work of the Ancient Egyptians is unrivalled.

5 - Some people believed that magic may have been used by the Ancient Egyptians.

6 - Limited technology limited the construction of the Ancient Egyptians from the Fourth Dynasty.

7 - The Romans learned the techniques of moving huge stones from the Ancient Egyptians.

Сколько минут должен длиться электролиз (сила тока 12 А) раствора едкого натра при получении водорода массой, необходимой для восстановления m г бензола (m = 1;2; 3; 4…20) в циклогексан? Покажите, что между длительностью электролиза (в минутах) и массой бензола имеется прямая зависимость. Приведите уравнение, отражающее эту зависимость. Пользуясь уравнением, вычислите длительность электролиза для восстановления 25 г бензола.
