The statement "The cruise industry has more than quadrupled passenger participation from 2000 to 2011" is True.
Here's why:
1. To quadruple means to increase by four times the original amount. So, if the cruise industry had, for example, 100,000 passengers in 2000, quadrupling that number would mean having 400,000 passengers in 2011.
2. If the cruise industry experienced more than a fourfold increase in passenger participation from 2000 to 2011, it means the number of passengers grew significantly over that period.
3. Therefore, the statement is true as it indicates a substantial growth in passenger participation within the cruise industry during the specified timeframe.
