The meaning of "You cannot go out and hang out with your friends." [closed]
Solution 1:
I would argue that the second is more likely, because if you can't go out for any reason, then "You can not go out" would be sufficient.
Alternately, "You can not go out or hang out with your friends" would emphasize that neither of those things are acceptable. Your other example should really be using "or" as well: "[Y]ou can not drink or smoke." Otherwise, it suggests that you can't do both of them together, but individually they are okay. Note "Don't drink and drive," for instance. It's okay to drink, and it's okay to drive- but not both at once!
