Question

which quotation supports the answer to part a?
a \didn’t farming end starvation and famine? didn’t it free us from having to wander the land looking for our next meal?\ (paragraph 2)
b \wear patterns, scratch marks, and dental decay all tell a story about the foods we eat and how they were prepared.\ (paragraph 6)
c \the most significant change in the teeth of early farming communities is the number and types of cavities.\ (paragraph 7)
d \certainly, we cannot go back to being nomads, but we can learn to eat nutritious diets and save our teeth.\ (paragraph 8)

Explanation:

To solve this, we need to assume the answer to Part A (likely about the impact of farming on health/diet or a related topic) and then find the quotation that supports it. Let's analyze each option:

• Option A talks about farming ending starvation and freeing from wandering for food—focuses on farming's role in food security, not directly on health/teeth.
• Option B mentions wear patterns, scratch marks, dental decay relating to food and preparation—more about methods of studying food, not a conclusion.
• Option C focuses on cavity changes in farming communities' teeth—specific to dental changes due to farming, likely supporting a Part A answer about dental impacts.
• Option D is about eating nutritious diets and saving teeth—more of a recommendation, not supporting a conclusion about farming's impact.

Assuming Part A was about dental changes from farming, Option C directly addresses the significant change (cavities) in early farming communities' teeth, supporting that answer.

To determine the supporting quotation, we analyze each option. Option C directly addresses a significant dental change (cavities) in early farming communities, likely supporting a Part A answer about farming’s impact on teeth. Other options focus on food security (A), food study methods (B), or diet recommendations (D), not aligning as closely.

Answer:

C. "The most significant change in the teeth of early farming communities is the number and types of cavities." (paragraph 7)
