Option 2: "Self-confidence is a skill that can be trained."

Explanation: The speaker explicitly mentions that self-confidence is a skill and can be trained, which aligns with the main idea of the text. This is supported by the phrase 'I use the word skill because I believe it can be trained,' indicating that self-confidence is not just a natural trait but something that can be developed.

Option 3: "Without self-confidence, one is useless as a soccer player."

Explanation: The speaker states, 'Without that skill...we are useless as a soccer player,' which directly supports this option. It highlights the critical role of self-confidence in achieving success in soccer, reinforcing the idea that lacking it can lead to failure.

Option 4: "Self-confidence means believing in your ability to accomplish any task."

Explanation: The speaker defines self-confidence as 'the ability or the belief to believe in yourself' and emphasizes that it involves believing you can accomplish any task, regardless of the challenges. This aligns perfectly with the option's meaning.

Option 5: "The speaker uses slides to explain his points clearly."
