Q: 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: The first written record of St Kilda may date from 1202 when an Icelandic cleric wrote of taking shelter on "the islands that are called Hirtir". Early reports mentioned finds of brooches, an iron sword and Danish coins, and the enduring Norse place names indicate a sustained Viking presence on Hirta, but the visible evidence has been lost. In the late 14th century John of Fordun referred to it as 'the isle of Irte (insula de Irte), which is agreed to be under the Circius and on the margins of the world'. The islands were historically part of the domain of the MacLeods of Harris, whose steward was responsible for the collection of rents in kind and other duties. The first detailed report of a visit to the islands dates from 1549, when Donald Munro suggested that:  "The inhabitants thereof ar simple poor people, scarce learnit in aney religion, but M’Cloyd of Herray, his stewart, or he quhom he deputs in sic office, sailes anes in the zear ther at midsummer, with some chaplaine to baptize bairnes ther."Despite the chaplain's best efforts, the islanders' isolation and dependence on the bounty of the natural world meant their philosophy bore as much relationship to Druidism as it did to Christianity until the arrival of Rev. John MacDonald in 1822. Macauley (1764) reported the existence of five druidic altars, including a large circle of stones fixed perpendicularly in the ground near the Stallir House on Boreray.Coll MacDonald of Colonsay raided Hirta in 1615, removing 30 sheep and a quantity of barley. Thereafter, the islands developed a reputation for abundance. At the time of Martin's visit in 1697 the population was 180 and the steward travelled with a "company" of up to 60 persons to which he "elected the most 'meagre' among his friends in the neighbouring islands, to that number and took them periodically to St. Kilda to enjoy the nourishing and plentiful, if primitive, fare of the island, and so be restored to their wonted health and strength.".
