A.I. Explanation:

First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main topic of false memories. It clearly states what false memories are. This follows the rule of Topic Sentence. It does not refer to any previous information, so it stands alone. Why other lines are not chosen? Paragraph 2 starts with 'During' which is a conjunction, so it cannot be first. Paragraph 3 starts with 'This' which is a pronoun, so it cannot be first. Paragraph 4 starts with 'Of course' which is also a conjunction, so it cannot be first. Paragraph 5 starts with 'Put' which is not a general statement, so it cannot be first.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the discussion about false memories. It uses the phrase 'Put another way' which signals a conclusion. This follows the Conclusive Words rule.
