What are the next letters? be gj lo qt

Its actually very simple! It's just a pattern! For the actual letters, you just skip two letters! This is what I mean:
 
B and E are two letters apart ( B, C, D, E,) G and J are two letters apart (G, H, I, J,) and so on. and the groups of letters are one apart! ( E, F, G,) (J, K, L,).

So your answer would be: VY

Hope this helps!

1. Code-switching

2. Ethnocentrism

Explanation:

Code switching refers to people changing the way they speak and behave as they approach different types of people and cultures so that their chances of fitting in are increased. This is what Bow is doing here to ensure that she can fit in with both her black and white friends.

Bow considering things from the perspectives of the attributes of her life, falls under ethnocentrism which is the tendency of people to look at other cultures and lives through their own circumstances and culture. For instance: an Asian not understanding why everyone else do not use chopsticks.
