Question

Read the excerpt from Act III, scene i of Romeo and Juliet. Benvolio: I pray thee, good Mercutio, let’s retire: The day is hot, the Capulets abroad, And, if we meet, we shall not ’scape a brawl; For now, these hot days, is the mad blood stirring. Mercutio: Thou art like one of those fellows that when he enters the confines of a tavern claps me his sword upon the table and says, ‘God send me no need of thee!’ and by the operation of the second cup draws him on the drawer, when, indeed, there is no need. Benvolio: Am I like such a fellow? Mercutio: Come, come, thou art as hot a Jack in thy mood as any in Italy; and as soon moved to be moody, and as soon moody to be moved. Which detail from the excerpt most foreshadows that Benvolio and Mercutio will fight the Capulets?

Answer 1

"if we meet, we shall not scrape brawl" i think. 
this line brings to light the ideas of a fight and in a sense is foreshadowing a future one 

Answer 2

Answer: Benvolio: I pray thee, good Mercutio, let’s retire: The day is hot, the Capulets abroad, And, if we meet, we shall not ’scape a brawl; For now, these hot days, is the mad blood stirring.

The first part of the dialogue between Benvolio and Mercutio foreshadows the trouble they will find. Benvolio asks Mercutio to go home. He believes that if they do not go, they are likely to fight the Capulets. Moreover, he explains that the weather is hot, which alters people's temper and makes them more likely to engage in a fight.
