Help?!?!?!?!?!?!?!?!?!?

Okay so i'm taking an online spanish course (penn foster), and in the study guide, you have to create a bunch of sentences with words you've learned so far. translating, reading, and those kinds of things are fairly easy, but when it comes to making my own sentences, my brain just kinda waltz's away. anyone got any tips?

¿cuál es la mejor traducción de esta oración: charlie and sophie will learn a lot about puerto rican culture in jayuya? carlos y sofía aprenderán mucho sobre la cultura de puerto rico en jayuya. carlos y sofía aprenden mucho sobre la cultura de puerto rico en jayuya.

Ayuda, para favor. correct incorrect
