Need to know, what must be true of a bill which has become law at a federal level? it must have been signed by the president. it must be in the best interest of all americans. it must have passed both the house and the senate. it must have been introduced into the senate before the house.

The first one because if the president doesn't approve it then it's a vetoed bill, unsigned bill, or it dies and none of those are options- another answer crossed out was that it had to be introduced in the senate because unless it's a money bill it can be introduced in either house- the second one is false too because we don't get to decide if they are good laws or not- and lastly yes it must be approved by the entire congress which is the house and senate but that isn't the only thing that will make a bill a law
hope this helps
