Detailed Instructions: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Problem:Passage: In Yorkshire, England, at the estate of the Duke of Rudling, the British Army converted the grounds into a training camp for war dogs. The camp is placed under the supervision of Sam Carraclough, the kennel caretaker, who immediately begins the process of selecting the best dogs for training, including Laddie, the young pup of the champion collie, Lassie. Joe Carraclough, now an adult, joins the Royal Air Force during the Second World War. Departing for training school, he is forced to leave behind his dog Lassie and her pup, Laddie.
Laddie, being considered as a "war dog", follows Joe to training school and then stows away on his master's bomber, just as it takes off on a dangerous mission over Nazi-occupied Norway. The two are forced to parachute when hit by enemy fire. Laddie then seeks help for his injured master. While they are separated, Joe is captured, and the dog is pursued by enemy soldiers. Laddie is sheltered, first by young Norwegian children who find him, and later by a freedom-fighter who is killed. Laddie finally reaches the prisoner-of-war camp where his master had been taken.
The German guards use Laddie to seek out his master who had escaped. In his search for Joe, who is forced into a labor detail on a coastal gun emplacement, Laddie is reunited with his master and thereafter the two race for their lives to reach friendly lines as the Nazis pursue them. Finally free, both Joe and Laddie make their way back to the Rudling estate to reunite with Lassie, Sam Carraclough, Joe's father and Priscilla, the Duke of Rudling's granddaughter.
Solution:
What is the full name of the person that Laddie searches for help for?
