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: During the Second World War, people converge on the Halfway House, an inn in the Welsh countryside. In Cardiff, the famous orchestra conductor David Davies is advised by his doctor to cancel a tour and rest, or he will live for only about three months. In London, Richard and Jill French argue about the education of their young daughter Joanna, who overhears them agree to divorce. Then Mr. French and Joanna go on vacation. Captain Fortescue is released from Parkmoor Prison; he was court-martialled for stealing the regimental funds. In a Welsh port, merchant captain Harry Meadows and his French wife Alice quarrel about their deceased son, a victim of the U-boats. Black marketeer Oakley departs from London for some fishing, while Margaret and her Irish diplomat fiancé Terence take a train from Bristol.
Oakley and Fortescue meet on the road; it turns out they know each other. Though Fortescue had scanned the countryside thoroughly with his binoculars in vain for the Halfway House, it mysteriously appears. When they reach it, the proprietor Rhys also seems to materialise out of thin air. He tells a puzzled Fortescue he was expected. When Oakley signs the register, he notices a long gap after the last signature, dated 1942, it being 21 June 1943. (The newspapers are a year old.) 
Others arrive; the Meadows request separate rooms. Rhys serves a grieving Alice tea in her room. She is shocked to see no reflection of Rhys in the mirror when he leaves. Mr. French notices his wife's handwriting in the register and suspects that Joanna arranged for them to stay in the same place. Later, Fortescue is sitting outside when he notices that Gwyneth, Rhys's daughter, casts no shadow, though Joanna, standing nearby, does. Joanna arranges a fake near-drowning, with the help of Captain Meadows, to try to reunite her parents; it nearly goes awry. Margaret and Terence quarrel when he is eager to accept a posting in Berlin (Ireland being neutral).
Student:
What is the full name of the character who notices that Gwyneth does not cast a shadow?
