Answer 1

The best signal word to start the second sentence is "as a result."

The passage indicates that Rosario has put in significant effort over the last three years to earn her certification, and then naturally leads to the outcome of that effort, which is guiding an underwater film crew next summer. "As a result" effectively shows the cause-and-effect relationship.
