Bot GPT 3.5 · Answer

The climber starts at an elevation of 380ft and then climbs an additional 182ft and 208ft. This means that the climber has ascended a total of 380ft + 182ft + 208ft = <<380+182+208=770>>770ft above sea level. To return to his original starting point, the climber needs to descend 770ft. However, he only descends 235ft. Therefore, the climber still needs to descend an additional 770ft - 235ft = 535ft. Thus, the correct answer is C. 535ft.
