Answer:
The best answer to compete the sentence: Cuando escribes un texto de comparación que incluye información de otras partes, es importante ________. Is: Incluir fuentes Which translates as: add the sources.
Explanation:
To understand this question we have to analyze it, first: We see the following: "cuando escribes un texto de comparacion" Cuando is When, escribes is you write but it doesn't include the you pronoun, because it is informal. "Un texto de comparación" is: a comparison text". Then, we see "que incluye información de otras partes. Which translates as "which, includes information from other sources" "Que is a relative pronuon that indicates that you are going to explain some characteristic/s about the subject. In this case otras partes is translated like other sources because "fuentes" or sources is the right answer but in this case the spanish level is too low so they use "partes". Then it says "es importante" which translates to "is importante". so the best option is "incluir las fuentes" because o two things doing a research or "investigación" is already done and implicit. So, it is done. Then, we need to find something that is not done but related to the text. the second options talks about "fuentes" which is the proper word to say "sources" instead of partes.
