Who was responsible for photographing and mapping much of Antarctica?

• A. Richard E. Byrd
• B. Roald Amundsen
• C. James Clark Ross
• D. Gerald Cassidy

Answer: (A)

The situation tests how polar regions were documented using aerial methods. Richard E. Byrd was an American explorer whose Antarctic campaigns pushed photography and mapping to new levels by flying over vast tracts of the continent and capturing extensive aerial photographs. These images were then turned into maps, letting scientists and planners understand coastlines, mountains, and ice features far more comprehensively than ground surveys alone. His work in the late 1920s and afterward established a foundation for how Antarctica could be charted from the air, which is why he’s recognized as the person responsible for photographing and mapping much of the continent. Roald Amundsen is celebrated for reaching the Pole by land and sea routes, James Clark Ross for early 19th-century coastal mapping, and Gerald Cassidy is not linked to Antarctic exploration.
