Final answer:
The three-field system brought about a significant increase in food production and enhanced the ability of people to resist disease by providing a better and more varied diet.
Step-by-step explanation:
The three-field system was an agricultural method that significantly improved medieval farming. The selections that most accurately describe the results of this system would be b) The production of food increased and d) People were able to better resist disease.
The three-field system increased the production of food by enabling more efficient use of land. It divided land into three sections; one for autumn harvest, one for spring, and the third lying fallow to replenish its nutrients. The increased food production supported population growth and helped establish more stable communities, fostering trade and diverse economies.
The improvement in food production and overall diet strengthened people's immune systems, thereby helping to better resist disease, particularly endemic diseases. With the introduction of new crops like peas, beans, and lentils, people received more essential nutrients.
