Mark: we need to protect halloween. halloween is a time for trick-or-treating, a tradition dating back to the middle ages. today, however, trick-or-treating is being cancelled in some towns. there are people who believe that there are some homes that mean to hurt trick-or-treaters with unsafe candy. while there maybe the occasional guilty party, the news on these incidents has been greatly exaggerated. additionally the police have put in to place a free process for checking candy. cancelling trick-or-treating in response to a possible threat that we are prepared for sends the wrong message.  greg: is trick-or- treating worth getting hurt over? it is odd to think that we spend so much time telling children not to take candy from strangers, but then one day a year we tell them the opposite. now, it is understandable that the fact that we have so many precautions in place, that it may seem like cancelling trick-or-treating is an overreaction. however, no system is perfect. even if one child gets hurt, that is too many. so why take that risk for a fun sized piece of chocolate? which argument has a counter argument?     a. both mark and greg b. only greg c. only mark d. neither mark nor greg
