Premise: Petru tried this three times , and when he was satisfied that the giant was really in his power he took out a handkerchief , bound the two little fingers of the giant together , drew his sword , and cried for the fourth time , ` Wake up , my brave man . '<br>When the giant saw the trick which had been played on him he said to Petru .<br>` Do you call this a fair fight ?<br>Fight according to rules , if you really are a hero ! ' '<br>I will by-and-by , but first I want to ask you a question !<br>Will you swear that you will carry me over the river if I fight honourably with you ? '<br>And the giant swore .
Hypothesis: The giant asked Petru if the fight was fair.
