Please choose the correct ending to complete the given sentence: Youth: [header] How to avoid talking in class [title] Switch your seat. [step] If your teacher allows you to pick your own seats, choose to sit next to a student you don't know. Sitting next to a buddy of yours makes it extremely difficult to focus on staying quiet.

Ending1: This is why it's important to pick an already-occupied seat to stay focused in class. [substeps] Sitting next to a total stranger who you've never seen before when you have class alone can actually increase your chances of having to talk. Ending2: Instead, switch your seat only once or twice a day. [substeps] If sitting to the end of the room always seems to be much more difficult, try sitting next to another student who shifts to your left and stays quiet. Ending3: It's also helpful to pick a seat closer to the front of the classroom. Close proximity to the teacher will make it harder for you to chit chat as the teacher will likely remind you to quiet down. Ending4: Likewise, if you just sit next to this student, you're likely not really focusing on the lecture. [substeps] Students who are involved in a lecture commonly do not pay attention to what's being said.
