Hi, Can you help me please I have to do these Spanish exercises.

A) transform the sentences of these exercises into personal obligations (without changing the people!)

Thank you in advance !

1. ¡Creo en mi y lucharé por la igualdad!
2. Demostraré a la gente que soy capaz de hacerlo.

1. No pensaré en que las mujeres no tenemos los mismos derechos que los hombres.
2. No me dedicare a criticar a las mujeres.
3. No juzgaré a una persona antes de conocerla.

I hope it is correct, I could not understand clearly what you needed.

Cusco is the oldest city 

Buenas noches. that is the correct way to say it.
