I'm not sure about the red panic button, I think it calls the fire Dep.

Answer 4

1 = A

2 = A (probably)

3 = ?

I am not sure of three since I don't attend your school.

Answer 5

Since the 1st question states "student w/ long hair" then you can assume that the relevancy in that sentence is the long hair.  Therefore, A would make more sense.

The second question could depend on what your teacher/book has taught you.  If she said, "Students can never go in there" then it's A.  If she said, "You can go in there if you ask me" then it's B.  There's no way anyone would know that answer for sure but you.  

The 3rd question seems like B would be more logical.  However, no one can tell what the red panic button in YOUR classroom will mean but you.  It may call the main office in your school but only you would know since you attend there.
