Q: This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Passage: The Koreans waited until a large Japanese fleet had left the island for a raid. Yi Jong-mu's fleet of 227 ships and 17,285 soldiers set off from Geoje Island toward Tsushima on June 19, 1419. The following day the fleet landed in Aso Bay . General Yi Jong-mu first sent captured Japanese pirates as emissaries to ask for surrender. When he received no reply, he sent out expeditionary forces, and the soldiers proceeded to raid the islanders and pirates and plunder pirate settlements. He found and rescued 131 Chinese captives of the pirates and 21 slaves on the island, burned 129 ships and 1,939 houses, and killed or captured 135 pirates. On the 26th day, the Korean army was ambushed on land by a Japanese army in an ambush at Nii, and suffered 150 casualties. The ambush was known to the locals as the Battle of Nukadake . In the weeks that followed, a truce was negotiated with the So clan on the island. The Korean expeditionary force withdrew and sailed back to the Korean Peninsula on July 3, 1419. and Korea gave up occupation of Tsushima. In subsequent diplomatic exchanges, Tsushima would be granted trading priveldges with Joseon, in exchange for maintaining control and order of pirate threats originating from the island.
A:
Did Yi Jong-mu rescue more people or kill more people on the island?
