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.

Let me give you an 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: 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.

OK. solve this:
Passage: Laurel and Hardy are seated at a dockside where Stan is fishing. Ollie sees a notice in a newspaper which says one Ebeneezer Laurel has died and left a large estate. Parties interested in the estate should go to the Laurel mansion for the reading of the will. Stan can't remember if Ebeneezer is a relative or not but they decide to go to the mansion anyway. They arrive during a thunderstorm and discover that Ebeneezer had been murdered and that the police had placed the notice in the newspaper to draw all of the relatives together to find out who committed the crime.
Stan and Ollie are shown to a bedroom to sleep overnight, which is the room in which Ebeneezer was murdered. They hear a strange noise and in the darkness see a pair of eyes which turns out to be a cat. They then hear a scream and decide to investigate.
Meanwhile, the butler is calling all of the relatives to a study telling them they have a phone call. After sitting in a chair and lifting the handset of the phone, the lights go out, there is a scream and a sound like a door slamming, and the relative is never seen again. Stan and Ollie return to their bedroom and get into the bed but a bat has flown into their room and is under their covers, which causes them to panic and run downstairs.
All of the other relatives have now disappeared and the butler calls Stan and Ollie to take a telephone call in the study. Ollie sits in the chair to take the call. This time, however, the lights stay on and it is revealed that the chair is affixed to a trapdoor into which each of the other relatives vanished. Ollie falls through the trapdoor, but is saved due to his having become wedged in the chair. The murderer (a man dressed in drag) appears through a secret door with a knife. A fight ensues, but then Stan and Ollie both wake up from a dream, fighting over Stan's fishing line at the dockside and then falling into the water.
Answer:
What surname do Stan and Ebenezer share?
