In what year did CUSS 1 drill the first deep-sea hole in 3,800 meters of water off Guadalupe Island, Mexico?

• A. April 1961
• B. May 1962
• C. March 1959
• D. January 1963

Answer: (A)

The main idea here is recognizing a historical milestone in offshore drilling. CUSS I achieved the first deep-sea borehole at about 3,800 meters of water off Guadalupe Island, Mexico, in 1961, specifically in April. This date marks the initial breakthrough in drilling at such great depths, establishing a precedent for future deep-sea operations. The other years listed don’t correspond to this record-setting event, so 1961 is the correct year for when that first deep-sea hole was drilled.
