Which of the following is true concerning bridges? select all that apply.

some bridges are high enough for ships to pass underneath
some bridges actual raise up for ships to pass underneath
some bridges swing sideways in order for ships to pass
some bridges use multiple methods to allow ships to pass

Your answer is:

Some bridges are high enough for ships to pass underneath and Some bridges raise up for ships to pass underneath.

The other two don't really make sense when you think about it! Swinging sideways is pretty much extremely out of the ordinary in reality and having multiple methods could possibly be true, but is also out of the ordinary and questions like these are usually choose two out of the four answers given. So, when you have two other great answers I would just go with those!

Hope this helps! Would really appreciate brainliest answer I'm trying to get to expert by today thanks!
