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.
One example is below.
Q: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
A: Who believes Fagin's gang make wallets and handkerchiefs?.
Rationale: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.
Q: Passage: Long ago, a young Plains warrior is tested by being the target of three different weapons. 
Centuries later, Ernest P. Worrell works as a maintenance man at Kamp Kikakee but hopes to become a counselor. He quickly becomes a valuable addition to the staff, skilled at Plains Indian Sign Language, used by Kikakee's owner, Chief St. Cloud. 
A small group of juvenile delinquents, the Second Chancers, come to Kikakee. Head Counselor Tipton assigns Kikakee's most experienced counselor, Ross Stennis, to be the boys' counselor. Stennis is unhappy with this assignment, and he treats the boys harshly. After he goes too far by intentionally causing Moustafa Jones, the smallest boy in the group, to nearly drown in the lake during swimming, only for Moustafa to be rescued by Ernest, the boys retaliate against Stennis's cruelty by toppling his lifeguard perch into the lake, badly injuring Stennis's leg in the process. Since Stennis is no longer able to perform his duties as a counselor and Kikakee is already shorthanded, Tipton offers Stennis's position to Ernest.
The Second Chancers initially give Ernest trouble, but they start to show respect during a campfire session when Nurse St. Cloud translates her grandfather's description of the warrior initiation ritual for his tribe. The initiate must hold still while a knife, a stone hatchet, and an arrow are thrown or shot at him. The courage of the young warrior apparently alters the course of each weapon to prevent it from striking him. The Second Chancers build a tepee only to find it burned. They fight Pennington, one of the regular campers, because he was responsible. Tipton is poised to expel them, but Ernest convinces him otherwise.
A:
What's the surname of the person who tries to drown someone?
