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: There is some evidence that Christianity made inroads into the Viking controlled Highlands and Islands before the official conversion at the end of the tenth century. There are a relatively large number of isles called Pabbay or Papa in the Western and Northern Isles, which may indicate a "hermit's" or "priest's isle" from this period. Changes in patterns of grave goods and the use of Viking place names using -kirk also suggest that the Christianity had begun to spread before the official conversion. According to the Orkneyinga Saga the Northern Isles were Christianised by Olav Tryggvasson in 995 when he stopped at South Walls on his way from Ireland to Norway. The King summoned the jarl Sigurd the Stout and said "I order you and all your subjects to be baptised. If you refuse, I'll have you killed on the spot and I swear I will ravage every island with fire and steel." Unsurprisingly, Sigurd agreed and the islands became Christian at a stroke, receiving their own bishop in the early eleventh century. Elsewhere in Scandinavian Scotland the record is less clear. There was a Bishop of Iona until the late tenth century and there is then a gap of more than a century, possibly filled by the Bishops of Orkney, before the appointment of the first Bishop of Mann in 1079.
What is the first name of the person ordered to be baptised?
