Multiple Choice

In 1978 lead was lowered to what percentage?

Explanation:
Lead content in paint is expressed as a weight percentage. In 1978 the federal limit for lead in residential paint was lowered to 0.06% by weight, which is the same as 600 parts per million. This is the value that matches the established standard from that period, so it’s the correct choice. The other numbers would indicate much higher or much lower lead levels and do not reflect the 1978 regulation.
