You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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: 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?.
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.

New input: Passage: Sissinghurst Castle Garden, at Sissinghurst in the Weald of Kent in England, was created by Vita Sackville-West, poet and writer, and her husband Harold Nicolson, author and diplomat. It is among the most famous gardens in England and is designated Grade I on Historic England's register of historic parks and gardens. It was bought by Sackville-West in 1930, and over the next thirty years, working with, and later succeeded by, a series of notable head gardeners, she and Nicolson transformed a farmstead of "squalor and slovenly disorder" into one of the world's most influential gardens. Following Sackville-West's death in 1962, the estate was donated to the National Trust for Places of Historic Interest or Natural Beauty. It is one of the Trust's most popular properties, with nearly 200,000 visitors in 2017.
The gardens contain an internationally respected plant collection, particularly the assemblage of old garden roses. The writer Anne Scott-James considered the roses at Sissinghurst to be "one of the finest collections in the world". A number of plants propagated in the gardens bear names related to people connected with Sissinghurst or the name of the garden itself. The garden design is based on axial walks that open onto enclosed gardens, termed "garden rooms", one of the earliest examples of this gardening style. Among the individual "garden rooms", the White Garden has been particularly influential, with the horticulturalist Tony Lord describing it as "the most ambitious ... of its time, the most entrancing of its type."The site of Sissinghurst is ancient and has been occupied since at least the Middle Ages. The present-day buildings began as a house built in the 1530s by Sir John Baker. In 1554 Sir John's daughter Cecily married Thomas Sackville, 1st Earl of Dorset, an ancestor of Vita Sackville-West. By the 18th century the Baker's fortunes had waned, and the house, renamed Sissinghurst Castle, was leased to the government to act as a prisoner-of-war camp during the Seven Years' War. The prisoners caused great damage and by the 19th century much of Sir Richard's house had been demolished. In the mid-19th century, the remaining buildings were in use as a workhouse, and by the 20th century Sissinghurst had declined to the status of a farmstead. In 1928 the castle was advertised for sale but remained unsold for two years.
Solution:
