Answer:
They must be convinced by a preponderance of the evidence.
Explanation:
In a civil suit, preponderance of the evidence would require a piece of evidence which outweighs other pieces of evidence which might be greater in number or amount but will not be as accurate.

By contrast, 'beyond reasonable doubt' requires a more strict examination of all evidence presented in order to convict in a criminal trial.
