Task: Question Generation
Input (English): Passage: For several months after the permanent camp was built, the colonists took short trips to  explore their surroundings. At the end of October 1685, La Salle decided to undertake a longer expedition and reloaded the Belle with many of the remaining supplies. He took 50 men, plus the Belle's crew of 27 sailors, leaving behind 34 men, women, and children. Most of the men traveled with La Salle in canoes, while the Belle followed further off the coast. After three days of travel, they learned of hostile Native Americans in the area. Twenty of the Frenchmen attacked the Native American village, where they found Spanish artifacts. Several of the men died on this expedition from eating prickly pear. The Karankawa killed a small group of the men who had camped on shore, including the captain of the Belle.From January until March 1686, La Salle and most of his men searched overland for the Mississippi River, traveling towards the Rio Grande, possibly as far west as modern-day Langtry, Texas. The men questioned the local Native American tribes, asking for information on the locations of the Spaniards and the Spanish mines, offering gifts, and telling stories that portrayed the Spanish as cruel and the French as benevolent. When the group returned, they were unable to find the Belle where they had left her and were forced to walk back to the fort.The following month they traveled east, hoping to locate the Mississippi and return to Canada. During their travels, the group encountered the Caddo, who gave the Frenchmen a map depicting their territory, that of their neighbors, and the location of the Mississippi River. The Caddo often made friendship pacts with neighboring peoples and extended their policy of peaceful negotiation to the French. While visiting the Caddo, the French met Jumano traders, who reported on the activities of the Spanish in New Mexico. These traders later informed Spanish officials of the Frenchmen they had seen.
Output (English): What is the name of the leader of the expedition that lost a captain to a group of Native Americans?
