The answer is “ Ellas hablan español.”
Answer:
Most of the time grammar comes after 'common sense" which is inevitable. Grammar rules don't matter anymore when it comes to informal conversation. We only pinpoint grammar errors when we don't understand the statement. So the easiest way to know if the sentence makes sense is to check if in all time subject agrees to its predicate or supporting details
Basically, your teacher is asking you to write about what you do outside of school, and a recent success (such as an A on a paper or you won an award for something). Also, your teacher wants to know about a real problem in your school (such as bullying, racism, sexism, etc.), and what you want to study next year in Spanish.
I cannot write the entire thing in space, but make sure you use SIMPLE verbs and phrases. You want to make this easier on you and your work. Use nouns that you know first and work your way up. I highly recommend SpanishDict.com for looking up nouns/verbs you don’t know, and it conjugates the entire verb list at the bottom of the definition. :)
