she was considered somewhat
unconventional among animal researchers.
for one thing, she hadnt been to college
yet.

Explanation:

The question is about identifying a transitional phrase to set up examples. "For one thing" is a transitional phrase used to introduce one of the reasons or examples (here, a reason for her being unconventional). "On the other hand" is for contrasting, "First" is for ordering (not specifically for examples), and "Rewatch" is not a transitional phrase. So "For one thing" is the correct option as it's used to present an example or reason.

Answer:

A. For one thing
