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.

Let me give you an 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.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is 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.

OK. solve this:
Passage: The western end of the Mendip Hills has, since 1972, been designated an Area of Outstanding Natural Beauty (AONB) under the National Parks and Access to the Countryside Act 1949. The Mendip Society, which was formed in 1965, helps to raise awareness of this designation and protect the area. The society now has 700 members and runs a programme of guided walks and educational presentations. The society also has a small grants fund to assist communities with the conservation and enhancement of the landscape and to encourage its enjoyment and celebration.As their landscapes have similar scenic qualities, AONBs may be compared to the national parks of England and Wales. AONBs are created under the same legislation as the national parks, the National Parks and Access to the Countryside Act 1949. In contrast to national parks, which have their own authorities and legal power to prevent unsympathetic development, very few statutory duties are imposed on the local authorities within an AONB. However, further regulation and protection of AONBs was added by the Countryside and Rights of Way Act 2000.In 2009 proposals were being prepared by the Mendip AONB in an attempt to get the Mendips designated as a Geopark, which is defined by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in its UNESCO Geoparks International Network of Geoparks programme as "A territory encompassing one or more sites of scientific importance, not only for geological reasons but also by virtue of its archaeological, ecological or cultural value."The Mendip Hills Partnership, which performs an administrative role, includes the five local authorities that cover the AONB, statutory bodies such as the Countryside Agency and English Nature, together with parish councils and other organisations and groups that have an interest in the conservation and care of the area. The Mendip Hills AONB staff unit of the partnership is based at the Charterhouse Centre in the heart of the AONB. The AONB Unit consists of four staff: a manager, project officer, support officer and part-time planning officer. They are supported by 20 volunteer rangers. In 2005 a proposal was submitted to the Countryside Agency to extend the Area of Outstanding Natural Beauty to Steep Holm and Brean Down in the west and towards Frome in the east.Many of the villages on the Mendips have their own parish councils, which have some responsibility for local issues. Local people also elect councillors to district councils or to unitary authorities. The 198 km2 (76 sq mi) of the AONB are split across four districts: Mendip District Council 87.67 km2 (33.8 sq mi),
Sedgemoor District Council 34.03 km2 (13.1 sq mi),
Bath and North East Somerset Council 36.95 km2 (14.3 sq mi), and
North Somerset Council 39.35 km2 (15.2 sq mi).
Answer:
What is the name of the unit that is supported by 20 volunteer rangers?
