A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first because it introduces the main topic of the text. It talks about the poor performance of the English football team, which is the main idea. It does not need any other sentence for context. This follows the rule of Topic Sentence. Why other lines are not chosen? The other paragraphs are not chosen because they do not stand alone. For example, Paragraph 2 starts with 'Firstly', which is a conjunction. Paragraph 3 starts with 'Instead', which also shows it is not independent. Paragraph 4 uses 'This has the effect', which refers back to something else. Paragraph 5 starts with 'It also', which is not independent either.

Concluding sentence: Why this is the last line? This paragraph is the last because it summarizes the negative effects discussed in the text. It wraps up the ideas about how the changes in football affect the game overall. This follows the rule of Summary Style.
