Step-by-step explanation:
Goran Kropp was a Swedish adventurer and mountaineer who is renowned for his attempt to summit Mount Everest without the use of supplemental oxygen. In 1996, Kropp set out on an astonishing expedition to essentially travel from Sweden to Everest and back using only his bicycle for transportation, carrying with him all the necessary equipment for the climb. Once at Everest, he aimed to ascend the mountain solo without oxygen support or the assistance of Sherpas. Unfortunately, Kropp's first attempt was unsuccessful due to the disastrous 1996 Everest season, but he achieved his goal on a subsequent attempt without using supplemental oxygen.
