12. Read and determine the pattern of development used in the passage. Avalanches (when a lot of snow falls from a mountain) may bury people under them. If the people are not found rapidly enough by rescue teams they will die of suffocation (not getting enough air) or of hypothermia (freezing cold). The chance of surviving an avalanche is as follows: • 92% if found within 15 minutes • 30% if found within 35 minutes (victims died of suffocation)• nearly cation)zero after two hours (victims die of injuries and hypothermia) *
