  • Mountaineering is now looked upon as the king of sports. But men have lived amongst the mountains since pre-historic time and in some parts of the world, as in the Andes and Himalayas, difficult mountain journeys have inevitably been part of their everyday life. However, some of the peaks were easily accessible from most of the cities of Europe. It is quite interesting that while modern mountaineers prefer difficult routes for the greater enjoyment of sport, the early climbers looked for the easiest ones, for the summit was the prize they all set their eyes on. Popular interest in mountaineering increased considerably after the ascent of the Alpine peak of Matterhorn in 1865 and Edward Whiymper's dramatic account of the climb and fatal accident which occurred during the descent. In the risky sport of mountaineering, the element of competition between either individuals or teams is' totally absent. Rather one can say that the competition is between the team and the peaks themselves. The individuals making up a party must climb together as a team, for they depend upon one another for their safety. Mountaineering can be dangerous unless reasonable precautions are taken. However, the majority of fatal accidents happen to parties which are inexperienced or not properly equipped. Since many accidents are caused by bad weather, the safe climber is the man who knows when it is time to turn back, howsoever t may be to press on and try to reach the summit. Mountaineering is different from other sports because

    A
    it is risky and dangerous
    B
    it can be fatal
    C
    it is most thrilling and exciting, there is no competition between individuals
    D
    None of the above
