Final answer:
Justice Smith helped his party survive by securing a reliable water supply with a well and ensuring food security by learning from captured Indians how to plant and by using aggressive tactics to acquire food from local villages.
Step-by-step explanation:
To ensure the survival of his party, Justice Smith implemented various strategies aimed at addressing the critical needs of the Jamestown colony. Primarily, Smith focused on essentials like water, food, shelter, and security. Two specific ways Smith helped his party survive were by ensuring a reliable water supply through the construction of a well, and by improving food security. He managed to do this by setting fires to threaten local villages for food, thus acquiring provisions to sustain the colony. Additionally, the captivated Indians at the fort taught the English colonists how to plant, which contributed to their self-sufficiency and food production. Despite the continued threat of rats destroying their stores, Smith's insistence on everyone working and contributing to the colony's welfare played a key role in maintaining the colony through tough times.
