Given the task definition, example input & output, solve the new input case.
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.
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.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
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 case for you: Passage: The Romney Literary Society, which built Literary Hall between 1869 and 1870, was organized by nine prominent men in Romney on January 30, 1819. With its establishment in 1819, the Romney Literary Society became the first literary organization of its kind in the present-day state of West Virginia, and one of the first in the United States. On February 4, 1819, the constitution of the society was adopted, which provided that the organization should be known as the "Polemic Society of Romney". The society founded its library in 1819 with the acquisition of two books, and by 1861 the society's humble library had grown to contain approximately 3,000 volumes, consisting of books on literature, science, history and art.
The Romney Literary Society commenced a movement to establish an institution for "the higher education of the youth of the community". As a result of this initiative, the teaching of the classics was introduced into the curriculum of Romney Academy in 1820, thus making the institution the first school of higher education in the Eastern Panhandle. In 1846, the society constructed a new building to house the Romney Classical Institute and its library, both of which fell under the society's supervision.The Romney Literary Society and the Romney Classical Institute both flourished and continued to grow in importance and influence until the onset of the Civil War in 1861. During the war, many members fought for the Confederate States Army forces and were killed during the conflict. The contents of the society's library were plundered by Union Army forces, and many of its 3,000 volumes were either scattered or destroyed. Following the war's end, only 400 of those volumes could be recovered, with just 200 remaining on the library's shelves.The Romney Literary Society reorganized on May 15, 1869. Following the reorganization, the society built Literary Hall between 1869 and 1870 while also undertaking an initiative to bring the West Virginia Schools for the Deaf and Blind to its old Romney Classical Institute campus. The construction of Literary Hall was part of the society's effort to revive the organization and reassemble its original library. The society set about recovering original volumes and purchasing new ones, and the library reopened with 700 volumes. For a period of ten years between 1870 and 1880, much of Romney's intellectual life centered on Literary Hall. As older members died, interest in the society began to dwindle. The society's meetings were held less frequently, and its last recorded meeting was held on February 15, 1886.
Output:
On what date did the society that was established in 1819 reorganize?
