How does the author use structure to create tension in the excerpt

What excerpt? But I would guess that he uses descriptive details to create tension. I still need to see the excerpt though

the tone of the passage is sympathetic to the forbidden love of romeo and juliet. the nurse plays a significant role in the play. she is responsible for making their meeting again possible. additionally, there is a sense of warning in the choice of words of the nurse. she seems to be authoritative when she calls romeo "scurvy knave", and at the same time the fact that she addresses to him as "sir" reflects respect. the nurse is "vexed", this word describes her confused state of mind. on the one hand, she finds romeo a fine and eloquent man, but on the other, it is thought that man's nature forces men to try to trick women.  

b. our party quickly made its way into the cave / but we failed to find our host [the cyclops] himself inside.
