Multiple Choice

Paint must contain less than what percentage of lead?

Explanation:
Lead in paint is tightly regulated because even small amounts can pose serious health risks, especially to children. The standard limit used for consumer paints is ninety parts per million by weight, which translates to 0.009 percent lead in the paint. That’s why the correct choice is 0.009 percent. It matches the regulatory ceiling: 0.01 percent would be 100 ppm and exceed the limit, 0.02 percent is 200 ppm and also too high, while 0.001 percent is only 10 ppm and far stricter than the stated requirement.
