Are dictionaries allowed in open book tests?

true or false?

True is the answer unless teacher says other wise

If you attend an online school, yes why not. While in school probably not. 

I would think that the reason why actors are used in media is because they are appealing to viewers and therefore able to entice them to buy something, go to the movie theater to watch that new movie that is coming out, or try to persuade people to take action.  Hopefully this helps.
