Parents should children and teens find age-appropriate volunteer experiences.

true
false

I find the usage of "should" problematic - does it mean it's necessary? good? required?

Generally, it's good for children to have age-appropriate volunteer experiences. It teaches them to appreciate other's work and responsibility. It's also good if parents help them organize it. Therefore, i would say that the answer is True.

However, children can also learn responsibility in other ways, too.
