2. Sophie was confronted with the problem of solving a crucial environmental issue. The coral reefs were facing possible extinction. She could not receive some support from her college professors, as they refused to provide their expertise, withheld their moral support, and did not supply her with the resources that she required (e.g. laboratory time). But, Sophie did not give up. She singularly decided to do something and was able to follow through despite the discouraging challenges. At last, she came up with the solution because of her indomitable spirit.
Explanation:
What is a theme? A theme of a story or an event is the lesson that can be derived from the story or event. It is not the sequence of events that make up a story, which is known as the plot, but the message or the bone of the story. The theme develops from the conflict or the central problem that is being tackled. The lessons that are learned in tackling the conflict or problem are the themes.
The answer would be: The thesis. Hope this helps!
