Answer:
The writer used the active voice in this passage.
Step-by-step explanation:
In the active voice, the subject performs the action stated by the verb, and the subject usually takes place before the verb. The word/words in Italics are the subjects, and they have taken place before the verb written in bold types in the passage quoted from the question.
I had never felt so alone. The wide sweep of the Andes stretched in front of me, a seemingly infinite expanse of ice and rock. The air cut into my cheeks, and blinded me, as I stood unsteadily looking down on the valley below. Then, for a moment, the skies cleared above me, and I saw a single, solitary condor rise on the breeze, effortless and free. I would be that condor. I would rise above my despair.
I think the answer is clear.
