Basically what the question is asking you is to explain whether or not it is the responsibility of educational leaders to prohibit (ban) tobacco around or near their property...it wants you to use evidence and stuff like that to support your answer...so just write whether or not you think it's their job and find evidence why or why not to help support it
The correct answer would be b.
You want to test them on what they should know, and see if they are on the level they should be at.
I believe the answer would be C. What makes things happen.
A) one-half
You need the hyphen in between the one and half
Well for starters cross out A) because everything doesn't have to be entertaining at the same time, cross out B) because its important to have evidence so people know its true, so its C) because showing evidence helps the audience know its correct.
