First sentence: Why this is the first line? This paragraph is the first sentence because it introduces the main idea of planning a gathering. It sets the stage for the rest of the text by talking about inviting friends. This follows the rule of Topic Sentence because it gives a broad overview of what is important for a successful event. Why other lines are not chosen? The other paragraphs are not chosen because they do not stand alone. For example, Paragraph 2 starts with 'To ensure a fun evening,' which shows it is linked to something before it. Paragraph 3 talks about setting up the area, but it assumes that the games are already chosen. Paragraph 4 starts with 'The night begins,' which means it needs earlier context.

Concluding sentence: Why this is the last line? This paragraph is the last sentence because it wraps up the event by explaining what happens at the start of the night. It uses Conclusive Words like 'the night begins,' which signals the end of the planning and the start of the fun.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects to Paragraph 1 because it continues the idea of planning for the gathering. The rule used here is Logical Order, as inviting friends helps to know how many games to prepare.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 follows Paragraph 2 because after choosing games, it is important to set up the area. This is a Broader to Specific Strategy, as it goes from the general idea of games to the specific setup needed.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects to Paragraph 3 because after setting up, the next step is to explain the rules. This follows the Chronological Order rule, as it shows the sequence of events during the night.
