Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following example:
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.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Reason: 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.

Now, solve this instance: Passage: Seconds is a mystery dealing with the obsession with eternal youth and a mysterious organization which gives people a second chance in life.
Arthur Hamilton is a middle-aged man whose life has lost purpose. He has achieved success, but finds it unfulfilling. His love for his wife has dwindled and he seldom sees his only child. Through a friend, Charlie, whom he thought was dead, Hamilton is approached by a secret organization, known simply as the "Company", which offers him a new life.
Hamilton arrives at a meat-packing plant for a meeting. He is given workman overalls and hat, then exits the facility by a different door and is seated inside a truck that takes him to another building. He disappears into a large complex filled with dark, empty hallways, where he awaits his transformation. The Company gives Hamilton the body of a young man through plastic surgery, and a new identity, namely "Antiochus 'Tony' Wilson". He later discovers this identity has been taken from someone who recently died.
Student:
What is the last name of the person who thought his friend was dead?
