The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The preparations that the colonists performed prior to the battle of Bunker Hill were the following.
The colonists were very aware of the imminent attack of the English troops. So Colonel William Prescott prepared the colonists to defend the hills that surrounded the town. At the very top of Beed Hill, almost 1000 colonists decided to build some walls and fortifications to impede the march of the British soldiers that came from the city of Boston.
The Battle of Bunker Hill was fought on Jule 17, 1775, and although the British won the Battle, they had many casualties against an inexéienced army And this represented a moral victory that gave confidence to the colonists.
