Read and listen to the article. Complete the article with numbers and measurements from exercise 2.

There are many amazing stories of human survival, but actually our bodies are very fragile and do not cope well with extremes. Polar explorers can cope with temperatures of ¹________, but only if they keep warm. Most people will collapse if their body temperature drops by only ²________, and if it drops by ³________, they'll die. Heat can be just as dangerous. Temperatures of 35°C are safe, provided humidity is not above ⁴________. High altitudes are dangerous too. We pass out when the pressure falls below ⁵________  of normal atmospheric pressure. This happens at about ⁶________   metres. Climbers can go higher because their bodies gradually get used to it, but no one survives for long at 8,000 metres. At high altitudes, lack of oxygen is another problem. At ground level, about ⁷______ of the air is oxygen. If that falls below ⁸________ , we die.
