First Poem:
I don't know what he gave you.
I don't know what I gave you, for a look a world,
for a smile the sky,
For a kiss, I don't know what I gave you for a kiss.
The correct answer is the first option "Visitando"
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).
