Task: Wrong Candidate Generation
Input (English): Context: Day 180 : Cenote Originally uploaded by Jess and Colin Cenotes are caves that formed in collapses in the limestone plateau that is the Yucatan and then filled up with water . Some of them are part of the world 's longest underwater cave system .

Correct Answer: We are sharing the pictures we took on our extended research trip .
Output (English): We want people to see how large the passages are in the underwater cave .
