Starting with the Question Mark

Spanish has a great advantage over other languages:
To lead with the question, could it be better?
Marked from the start, with no need for
Inflection. For one with great thirsts,
The bottom of the glass is first
Before the pouring has finished
Completed, knowing: this is not
A statement and you will not
Box me in with an ending,
For from the beginning
I am the start of something?
