A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first because it introduces the main topic. It talks about Sepahua, a town, and gives a broad overview of its location. It does not refer to any previous information. Why other lines are not chosen? Paragraph 2 starts with "That pocket" which refers back to the previous sentence, so it cannot be first. Paragraph 3 starts with "In 2001" which gives a specific time and context, so it cannot be first. Paragraph 4 starts with "It abolished" which refers to a previous system, so it cannot be first. Paragraph 5 starts with "Instead" which shows a contrast and needs prior context, so it cannot be first.

Concluding sentence: Why this is the last line? This paragraph is the last because it wraps up the discussion about the government's actions. It gives details about the new system and its aim, which brings together the earlier points.
