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: In Cardiff, a young Polish sailor named Bronislav Korchinsky returns from his latest voyage to visit his girlfriend Anya. After he finds a woman named Christine living in her apartment, the landlord tells him that he evicted Anya and gives him her new address, which is also the home of a young girl named Gillie Evans, an orphaned tomboy who lives with her Aunt. Gillie's angelic face hides the fact that she is a habitual liar. She dearly wants a cap gun so she can play "Cowboys and Indians" with the boys in her neighbourhood. Korchinsky arrives shortly after she gets into a fight; she begins to like him as she leads him to her apartment building.
Korchinsky finds Anya in her new flat, but she wants nothing to do with him. Dissatisfied with waiting while he is at sea, she has been seeing another man, a married sportscaster named Barclay. When Korchinsky, furious with jealousy, assaults her, she defends herself with a gun, but he takes the gun from her and shoots her dead. Gillie witnesses the incident through the letter box in the apartment door. When the landlord investigates the noise, Gillie hides in a cupboard, and when Korchinsky hides the gun near her, she takes it and runs into her apartment. Barclay then arrives to visit Anya, but, finding her dead, quickly flees. A neighbour discovers the body shortly afterward and summons the police.
Student:
What is the first name of the person who has been seeing Barclay?
