He convinces Toby that his Aunt Olive and Uncle Daniel don't love him or want him back and hides their letters. Toby resigns himself to circus life, even scoring himself a much bigger role, when he replaces the uppity, self-centered boy bareback rider after an injury.

Mr. Stubbs follows him and Toby decides to take the chimp home with him. Soon after, though, Mr. Stubbs is chased by a hunter's dog.

[EX Q]: Passage: After their HIV positive mother's death, Derick and Margaret collect wood and construct a human-length box with wheels. Then, they journey with it from Kampala to Kasangombe in a heartbreaking bid to overcome poverty and experience hope. The journey throws them dangerous experiences on unpredictable Ugandan roads. Their mother's dying wish had set them off on a seemingly impossible journey to find a relative they do not even know.
Before her death, she leaves them an envelope addressed to her sister (their auntie) who is married to a hard-working man living in a distant village called Kasangombe with their kids. Ingeniously, Derick creates a coffin using wood he collected from a rubbish dump and adds luggage bag rollers brought by Margaret. On their journey from Kampala City to their aunt's place, they are offered a lift by a seemingly kind man (played by Joel Okuyo Atiku) in a truck who is amazed by their "box". He introduces them to a kid he had taken under his wings relaxing at the back and shows them a photo of a house they can possess if they work for him. At night though, Margaret sees a scary dream where their helper is not exactly as kind as he seemed so she runs out of the truck. Derick follows and the boy throws out their coffin before waving. They walk the rest of the distance.
Initially, their uncle (played by Isaac Muwawu) did not want them in his house because he thought they were HIV-infected. Derick overheard him quarrel with his aunt at night and shook Margaret in the morning from another dream (this time beautiful, where both siblings were smiling and enjoying a picnic in a glorious garden with their aunt, uncle, cousins, dead parents and some whites). Derick convinced her to walk away from the home with him but without a reason.
Question: How do the pair of siblings finish the last leg of their journey?
[EX A]: They walk.

[EX Q]: Passage: Sonora Webster lives with her sister and abusive aunt during the Great Depression. She learns that because of her accidentally letting the cows loose and her suspension from school, her treasured horse Lightning has been sold and she will be placed in an orphanage. Instead, Sonora slips out of the house during the night. She ends up at a county fair and sees a performance by Marie, a diving girl who rides a horse off a platform, and aspires to do the same. Doc Carver, Marie's employer, tells her she is too young but gives Sonora a job as a stable hand due to her ability with horses, and she begins traveling with them. Doc's son Al wins a wild horse in a card game and Sonora names him Lightning. She later surprises Doc by taming and riding Lightning, so he promises to train her as a diving girl if she can mount it while it's moving, which she succeeds after multiple attempts.
Marie falls and dislocates her shoulder, leaving her unable to perform, and Sonora steps in. Although she has never dived with Lightning, their first jump is successful. Marie becomes jealous, and as Doc tires of her diva-like behavior, she quits rather than share billing with Sonora. Al develops a romance with Sonora that strains his relationship with his father, leaving after a particularly bad fight. Al promises to write to Sonora, but Doc hides his letters. As Doc and the new stable hand Clifford leave the farm in search of work, Lightning falls ill with colic. Al returns, and he and Sonora work together to heal Lightning. Doc fails to find any jobs, but Al announces he has arranged a six-month contract to perform at the Steel Pier in Atlantic City, New Jersey, reconciling father and son. Doc passes away en route from a heart attack, and Al assumes his father's role as show presenter. Sonora searches for Doc's jacket to give Al confidence on his first show, and finds one of Al's letters inside, confessing his love for her, letting him know she feels the same.
Question: Whose letters did Doc Carver hide?
[EX A]:
Al.
