Whar subject pronoun would you use when talking to your teacher

Usted. It is the polite way to address and adult that you don't know, a teacher, a stranger, the elderly, etc

Usted = you

Example sentence: ¿Usted tiene un pluma que puedo usar?
Do you have a pen I can borrow?
(also side note: any word ending with -ma is masculine. Pluma is slang for pen and it is masculine. You can also say boligrafo for pen.)

The only change would be to add the accent on esta (on the a) in esta in number 15.

The translation is "the illiteracy rate is high but they do not get job opportunities. unemployment violence violence crime corruption" but i do not understand the question?
