Can someone explain to me why it is unreasonable to assume that banning smoking in workplaces offers some protection to people outside of their workplaces? Those people presumably have some protection from secondhand smoke when they visit other people's workplaces, such as grocery stores or restaurants.

I see why E is correct, but I fail to understand why C isn't also correct. Are we living in a hypothetical world where no one is ever a customer or visitor in someone else's workplace?

@MadlynV it flags if you take too much time even if you answered correctly
