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.

Passage: After "Jingle Bells" melody, played on a calliope, is heard during the brief opening credits, two children, who appear to be five or six years old, are seen in a bunk bed, saying goodnight to their mother. The boy, Dick, is in the upper bunk and the girl, Ann, who is in the lower bunk, says, "oh, Dick, I wonder if Santa ever got our letter". 
The visuals become blurry and a male narrator states, "yes, Ann, far up in the North Pole, Santa is reading your letter now". In a spacious living room setting, seated in a large easy chair and dressed in full traditional apparel, Santa is holding a sheet of paper which is shown in close-up to depict, in large-lettered children's handwriting, "Dear Santa / DicK and I would LiKe To visiT You. / CouLD we PLEase visit you at The NoRTH PoLE beFore CHriSTmAs ? / DicK And ANN".
Upon reading the letter, Santa says, "Why not" and calls elf Toby to prepare the magic helicopter and bring the two children to him. Toby responds, "your'all words are my command, Santa". Appearing in Dick and Ann's bedroom, Toby awakens them with the words, "hurry up and get dressed and we will fly to Santa", as the narrator explains to the audience, "it's just a short hop in the magic helicopter". 
Walking through a castle-style entrance inscribed "Santa", Toby leads Dick and Ann into Santa's living room and is then dismissed by Santa who, still seated in his large easy chair, takes the children onto his lap, as documentary footage of seasonal celebrations and Santa pageantry appears on the screen, with the narrator recounting how Christmas is observed in various cities and towns. A Christmas parade, with main focus on Santa, is seen in the Pennsylvania city of McKeesport. Santa gives Dick and Ann a tour of "The Village Toy Shop" which appears as a series of Christmas doll and toy exhibits as well as displays in a large department store. Santa then leads them to his toy warehouse where preparations are made for Christmas Eve distribution.
Who does the girl wonder aloud to about Santa receiving their letter?
