The Whitewater controversy, Whitewater scandal (or simply Whitewater), was an American political episode of the 1990s that began with an investigation into the real estate investments of Bill and Hillary Clinton and their associates, Jim McDougal and Susan McDougal, in the Whitewater Development Corporation, a failed business venture in the 1970s and 1980s.
The Whitewater controversy happened within the last 10 years.
It's definitely incorrect because the text said it was an episode of the 1990s, which were more than 10 years ago. Again, I think the system is bad at calculating dates/times using the current year as a reference point and it gets confused by these types of questions.
