<span>an external threat to Denmark
Not only is there unrest within the castle because of the previous King's death and Hamlet's moodiness, there is also a threat coming from another country. This means that Claudius will have to take charge and make sure that Fortinbras' armies do not invade in such an unstable time. </span>
Rouge waves are basically just smaller tsunamis. They both carry explicable force and they can form at any place where the conditions are right. However, rouge waves may be more common.
I believe that the best answer for this question is a counterargument. Whatever the writer is in support of is the argument. The opposite side would be whatever the opposing, or countering, argument is. For example, if someone is in support of free college, they would support their argument and perhaps include some information about the counterargument, which would be not supporting free college. Hope this helps.
