Question

which claim is the most effective for the argument that the minimum age to get a drivers license should be changed to 18?
some 16-year-olds help out by driving their younger siblings to school, so changing the minimum driving age to 18 would be a problem for them.
some 16-year-olds are mature enough to drive, but changing the minimum driving age to 18 would be an overall benefit for everyone.
changing the minimum driving age to 18 would mean safer roads for everyone, since less-experienced drivers are more likely to have accidents.
changing the minimum driving age to 18 shouldnt cause too much of a problem, because its only two years older than 16.

Explanation:

The most effective claim directly supports the argument with a clear, evidence-based benefit tied to the core concern of driving: safety. It links raising the age to a universal positive outcome (safer roads) with a logical reason (less-experienced drivers have more accidents), which is a strong, persuasive point for the policy change. Other options either oppose the change, offer weak justifications, or downplay the impact without a meaningful supporting reason.

Answer:

Changing the minimum driving age to 18 would mean safer roads for everyone, since less-experienced drivers are more likely to have accidents.
