In Julius Caesar, act 2, scene 4, what is the purpose of imagery in this excerpt?

SOOTHSAYER. None that I know will be; much that I fear may chance.
Good to morrow to you. Here the street is narrow.
The throng that follow Caesar at the heels,
Of senators, of praetors, common suitors, will crowd a feeble man almost to death.
I’ll get me to a place more void, and there
Speak to great Caesar as he comes along.

Select three options:
1) to emphasize how dangerously packed the streets are
2) to indicate that the soothsayer is a fraud
3) to show that the sooth will send the people home
4) to help the reader picture the excitement in the crowd that follows Caesar
5) to demonstrate how determined the soothsayer is to deliver his message to Cesar
