Task: Question Answering
Input (English): Context: We thought Victor might clam up in his presence , but he did not and it became apparent through sign language that this man was also not concerned about recriminations for talking about the pollution . In fact it appeared that the entire commune was so fed up with the poison seeping through their night and day that they were totally fearless as to any consequences caused by their speaking out . This was highly refreshing . We ' ve never encountered people willing to be so open to talk about their problems before . 
Question: Why could not everyone understand Victor 's conversation with the man ?
Output (English): Victor was speaking through sign language .
