• D-1 involves filtering the ballast water, while D-2 involves neutralizing it with chemicals.

• D-1 applies to water taken from ports, while D-2 applies to water taken from the open ocean

• D-1 is a recommendation, while D-2 is a mandatory requirement.

What was the final compliance deadline for any remaining existing ships to meet the D-2 standard, regardless of their IOPP survey schedule?

• September 8, 2020

• September 8, 2024

• September 8, 2017

• December 31, 2025

Which document must be carried on board to demonstrate that a ship is in compliance with the BWM Convention's requirements?

• The Engine Room Log Book.

• The ship's official log book.

What is the most significant ecological threat posed by aquatic invasive species (AIS) introduced via ballast water?

• They compete with native species for food and habitat, disrupting the ecosystem.

• They increase the water's turbidity, making it cloudy.

• They cause genetic mutations in native marine life.

• They provide a new food source for native predators.

Which of the following is a direct economic threat of AIS introductions?

• Increased costs for building larger and more robust ships.

• Clogging of industrial water intake pipes and damage to fisheries.

• The high price of saltwater used for ballast exchange.

• Decreased shipping traffic due to fear of contamination.
