Answer:
The answer to: Choose the best word to complete the phrase. _____ (i know) la abuela vieja. Is: Yo conozco.
Explanation:
"I" is the personal pronoun to "me" in the first person. In Spanish it's equivalent is "YO" and it goes before any verb. The word Know is "conocer" in Spanish it is conjugate as "conozco" in first person, so the right answer is Yo conozco. In this case there are two ways to answer the first one which is formal and the most appropriate way is "Yo conozco" because it is the proper way to say I know. But there is another way, the informal way "conozco la abuela vieja". This is also correct, but it is incomplete because even though the verb is in the first person and in the present form of the verb the subject is avoided. It is not proper for academic works.
