нужен краткий пересказ римерно30 слов Robert Scott

1. Finally on 12 January Scott and his men got to the South Pole. There they saw a Norwegian flag; Amundsen had got there two weeks before.

The people in Scott's expedition died on their way back to the camp. Winter killed them.

Scott had bought all the equipment: warm clothes, food, electric sledges and Siberian ponies.
