D. That Caesar is not immortal like many believe him to be
Explanation:
After Julius Caesar conquered Pompey in war, he returned to jubilation and praises from his people. On the sideline was Senator Cassius who believed that Caesar would gain autonomy as king. He therefore began plotting the death of Caesar. He wanted others to join him in this conspiracy.
He spoke to Brutus, convincing him that Caesar was not immortal nor a god. He gave instances of when he and Caesar engaged in a swimming competition and then Caesar began to sink but he came to his aid. He also talked of a time when Caesar was sick and vulnerable. He recanted these events to tell Brutus that Caesar was not immortal as many believed he was. Therefore, he could be killed. He also forged letters believed to be from the citizens who stated that they were not happy with Caesar and that Brutus should take charge. Brutus finally joined in the conspiracy and execution of the murder of Caesar.
Eventhough Robert Frost did write in several meters his favourite one and the most used was iambic, he was very good changing little parts to hide iambic meters, so he´d write in iambic but still sound fresh and his poems seem to flow better.
