Task: Wrong Candidate Generation
Input (English): Context: There is some truth in that answer ; but it is not the whole story . The crisis is not the creation of " greedy bankers " and speculators : it is the result of too much debt , after governments and central banks failed to constrain the credit expansion of the early years of this decade . Bankers then irresponsibly exploited the opportunities afforded by an easy credit regime . 
Question: Why did the bankers try to exploit the opportunities ? 
Correct Answer: They are bankers and are trying to get money and riches .
Output (English): They did n't know any better they were just doing what needed to be done .
