Answer:
George committed scientific fraud.
Explanation:
Scientific fraud is intentially miscronstruing or misreporting data in order to prove something that the scientist wants to show. Making a mistake, if it's honestly a mistake, like Maria did, is not scientific fraud because presumably if she realizes her mistake she will correct it. Naomi and Hilda are both standing up for what they believe in. George is the only one intentionally lying and reporting false data.
