Carefully reading the passage, especially concentrating on the first sentence in the second paragraph about a long period and the second and third sentences in the last paragraph discussing the temptation to believe in Columbus and Magellan's role, suggests that option 2 is correct. The passage corrects the misunderstanding that Columbus and Magellan played a significant role in determining the north as the top.
The placement of the north at the top was not due to it being associated with darkness, as mentioned in the second paragraph. Likewise, it wasn't chosen as the top because other religions, such as Christianity and Islam, regarded the east and south, respectively, as the top, as explained in the fourth paragraph. Additionally, early Christianity considered the east sacred, as indicated in the third and fourth paragraphs, but this did not lead to placing the north at the top.
The conclusive statements in the third paragraph, specifically the expression "look up to him" in the last three sentences, strongly support option 2 as the obvious choice.
The concluding part of the last paragraph, especially certain final sentences like "When Columbus describes the world, it is in accordance with east being at the top. Columbus says he is going towards paradise, so his mentality is from a medieval mappa mundi," clearly indicates that he adopted an eastward orientation for religious reasons. It's worth noting, as mentioned in the previous paragraph, that mappa mundi were Christian maps from that era.
Referring to the last paragraph, specifically the final sentence "We have got to remember that at the time, no one knows what they are doing and where they are going," it is evident that there is uncertainty about the primary factor influencing the choice of a north-oriented map. This supports the assertion made in choice (4).
Carefully reading the passage, especially the initial two paragraphs, makes it clear that option 1 is the right choice. The following paragraphs also confirm that influences such as religion and deference to authority, rather than natural phenomena, were factors in the map-making of others.
Read the sentence and infer the writer's tone: "The politician's speech was filled with lofty promises and little substance, a performance repeated every election season."
