Question

1. which three statements should be included in an accurate summary of \a scratch tells all\? a finely ground bits of starches cause most cavities because they are trapped between teeth. b consuming large amounts of meat and fat does not contribute to the decaying of tooth enamel. c people from the farming era had 50 percent more dental defects than people of the pre - farming era. d while farming has benefited society in many ways, its products have increased the rate of tooth decay. e humans have made a costly mistake by consuming too much starch, leading to an increase in tooth decay. f foods like nuts, berries, roots, and fruit are what pre - farmers ate; farmers ate corn, barley, wheat, and rice. g research shows that across the world, the increase of farming also increased the percentage of tooth decay.

Explanation:

To solve this, we analyze each option based on what a summary of "A Scratch Tells All" (likely about dental health and farming's impact) would include:

• Option B: Consuming meat/fat not causing enamel decay is a key point about dietary impacts on teeth.
• Option D: Farming’s benefits but its products increasing tooth decay captures the central theme of farming’s impact on dental health.
• Option G: Global research linking farming increase to tooth decay percentage rise supports the main idea.

Other options: A (focuses on starches but may not be the main point), C (specific 50% stat might be detail, not summary), E (judgmental "costly mistake" not objective summary), F (food list is detail, not summary).

Answer:

B. Consuming large amounts of meat and fat does not contribute to the decaying of tooth enamel.
D. While farming has benefited society in many ways, its products have increased the rate of tooth decay.
G. Research shows that across the world, the increase of farming also increased the percentage of tooth decay.
