Task: Question Answering
Input (English): Context: OK , here 's what happened . We took an excursion boat out of Juneau to see some whales . The boat had a naturalist on board who told us we would be lucky to see orcas , but humpbacks were common . Soon , however , he got a call from a sister ship that had spotted some orcas , looking like they were on a hunt . 
Question: What might have happened if they had n't gotten the call ?
Output (English): They would have seen only humpback whales .
