First sentence: Why this is the first line? This paragraph is the first line because it introduces the main topic of competence and performance. It gives a broad overview of what the text will discuss. It does not refer to any previous information, so it stands alone. This follows the rule of Topic Sentence. Why other lines are not chosen? The other paragraphs are not chosen because they do not meet the criteria for being independent. For example, Paragraph 2 starts with 'But,' which is a conjunction. Paragraph 3 uses 'For example,' which is not an independent statement. Paragraph 4 uses 'You need to study code firstly,' which is specific and assumes prior knowledge. Paragraph 5 also starts with 'Then,' which indicates a continuation of thought.

Concluding sentence: Why this is the last line? This paragraph is the last line because it wraps up the discussion about competence and performance. It shows the result of studying the code and trying to drive. The phrase 'which reflects your performance' indicates a conclusion to the topic discussed.

Paragraph pairs:

• Pair 1 (Paragraph 1 → Paragraph 2): Paragraph 2 connects with Paragraph 1 because it continues the discussion about knowledge and performance. The use of 'But' shows a contrast between what a person knows and how it is shown in performance. This follows the Connector Strategy.
• Pair 2 (Paragraph 2 → Paragraph 3): Paragraph 3 connects with Paragraph 2 because it gives an example of the topic discussed in Paragraph 2. The phrase 'For example' shows that it is providing a specific case related to the general idea of performance. This follows the Topic Example rule.
• Pair 3 (Paragraph 3 → Paragraph 4): Paragraph 4 connects with Paragraph 3 because it explains what is needed to show competence. The phrase 'which indicates the competence in you' directly relates to the example of driving. This follows the Broader to Specific Strategy.
• Pair 4 (Paragraph 4 → Paragraph 5): Paragraph 5 connects with Paragraph 4 because it continues the idea of competence and shows how it relates to performance. The word 'Then' indicates a logical order of actions, moving from studying to driving. This follows the Logical Order rule.
