Please choose the correct ending to complete the given sentence: Youth: [header] How to impress your dance teacher [title] Introduce yourself. [step] When you begin taking a new dance class, make a point of introducing yourself to the instructor. Not only is this polite, but it sets you apart from other students and creates a rapport with the teacher.

Ending1: This helps you to put things in perspective, and it shows that the teacher enjoys your technical skills and expertise. [substeps] Initially, introduce yourself to the instructor. Ending2: Make sure to introduce yourself at a moment that is convenient to the instructor (i.e. not right when they are trying to start the class, or when they are busy with another student). Ending3: [substeps] Don't make your introduction brief. If you go too long without introducing yourself, you will end up yelling over every word of it. Ending4: This can further build upon your strengths as a dancer and it opens up more opportunities for you to advance in the business world. [substeps] Make sure your introduction is formal, not like a formal speech on the street, or like you're delivering your opening lines directly to the class.
