Read the following passage carefully and answer the questions given below.

Mountaineering, also called mountain climbing, the sport of attaining, or attempting to attain, high points in mountainous regions, mainly for the
pleasure of the climb. Although the term is often loosely applied to walking up low mountains that offer only moderate difficulties, it is more
properly restricted to climbing in localities where the terrain and weather conditions present such hazards that, for safety, a certain amount of
previous experience will be found necessary. For the untrained, mountaineering is a dangerous pastime.
Climbing mountains embodies the thrills produced by testing one’s courage, resourcefulness, cunning, strength, ability, and stamina to the utmost
in a situation of inherent risk. Mountaineering, to a greater degree than other sports, is a group activity, with each member both supporting and
supported by the group’s achievement at every stage. For most climbers, the pleasures of mountaineering lie not only in the “conquest” of a peak
but also in the physical and spiritual satisfactions brought about through intense personal effort, ever-increasing proficiency, and contact with
natural grandeur.
Early attempts to ascend mountain peaks were inspired by other than sporting motives: to build altars or to see if spirits actually haunted once-
forbidden heights, to get an overview of one’s own or a neighbouring countryside, or to make meteorological or geological observations. Before
the modern era, history recorded few attempts to ascend mountain peaks for the mere sake of the accomplishment. During the 18th century, a
growing number of natural philosophers—the scientists of their day—began making field trips into the Alps of Europe to make scientific
observations. The area around Chamonix, France, became a special attraction to those investigators because of the great glaciers on the Mont
Blanc chain.
By 1870 all of the principal Alpine summits had been scaled, and climbers began to seek new and more-difficult routes on peaks that had already
been ascended. As the few remaining minor peaks of the Alps were overcome, by the end of the 19th century climbers turned their attention to
the Andes Mountains of South America, the North American Rocky Mountains, the Caucasus at the western edge of Asia, Africa’s peaks, and
finally the vastness of the Himalayas.
