A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first because it introduces Mahatma Gandhi and gives important information about him. It tells us when and where he was born and what he did. This is an introduction to the main topic. It does not need other sentences to understand it. Why other lines are not chosen? The other paragraphs are not chosen because they do not stand alone. For example, Paragraph 2 starts with 'His philosophy,' which needs context. Paragraph 3 starts with 'Gandhi's commitment,' which also needs context. Paragraph 4 starts with 'His efforts,' which refers back to Gandhi. Paragraph 5 starts with 'Even now,' which needs earlier information to make sense.

Concluding sentence: Why this is the last line? This paragraph is the last because it wraps up the main ideas about Gandhi. It shows how his teachings are still important today. It gives a final thought about his influence.
