Answer:
1. The declaration is true
This is because the government often states the technology throughout the command and control legislation which the companies should use in the manufacturing.
2. This statement is false.
This is because laws on command and control are still not effectively enforced to reduce pollution, and there are therefore numerous deficiencies.
3. This statement is false.
This is because command and control are often not versatile, since all polluters require the same technology to control pollution and the same standards. It doesn't distinguish between the companies that find it easy or expensive to meet pollution standards.
