Question
Decades ago, most of the paint used in the US was lead-based because it was cheap, long lasting and widely available. When scientists recognized that this was polluting the air with toxic lead, laws banned lead- based paint, and the paint industry developed more cost-effective paints that do not contain lead. What was most likely the type of problem lead-based paint had that was solved by using paints without lead? limited availability ineffective for most uses lack of durability health risk to users

The correct answer is D.
Explanation
## Step1: The question asks what problem was most likely solved by using paints without lead instead of lead-based paint. The options provided are: Limited availability, Ineffective for most uses, Lack of durability, and Health risk to users.## Step2: We need to evaluate each option based on the known issues associated with lead-based paints.## Step3: The first option is 'Limited availability'. This is not a known issue with lead-based paints. In fact, lead was widely used in paints before the health risks were understood.## Step4: The second option is 'Ineffective for most uses'. This is also not a known issue with lead-based paints. Lead-based paints were widely used because they were effective for many uses, including as a corrosion inhibitor, pigment, and for their ease of application.## Step5: The third option is 'Lack of durability'. This is not a known issue with lead-based paints. Lead-based paints were known for their durability, which is one of the reasons they were widely used.## Step6: The fourth option is 'Health risk to users'. This is the known issue with lead-based paints. Lead is a toxic substance that can cause serious health problems, especially in children. This is the problem that was most likely solved by using paints without lead.
