Para tomar notas se usa un boligrafo that i said was to take notes you use a pen.
Answer:
C.) aquéllos
Explanation:
Aquéllos means those. So, you are trying to say those are cheap.
Answer: Every proper sentence in Spanish must have a subject and a verb. There is also a proper place for subjects and verbs in a sentence. Begin a sentence with the subject (the person, place, or thing you're talking about). Follow that with the verb, and then the rest of the sentence (where, how, etc).
The answer would be 3) Los. The object of the sentence, "boligrafos", is male and plural.
