Question

1. the following question has two parts. first, answer part a. then, answer part b. part a what inference can be made based on paragraph 4 of \a scratch tells all\? a people with tooth decay generally live shorter lives. b people of the farming era were not aware of tooth decay. c people with a poor diet may also have a shorter life span. d people of the non - farming era were concerned with dental hygiene.

Explanation:

To solve this, we analyze each option:

• Option A: The passage likely doesn't directly link tooth decay to lifespan in this way.
• Option B: There's no indication farming era people were unaware of tooth decay.
• Option C: A poor diet (which can cause tooth decay) being linked to shorter lifespan is a reasonable inference, as diet affects health and lifespan.
• Option D: The passage likely doesn't support this about non - farming era dental hygiene concerns.

Answer:

C. People with a poor diet may also have a shorter life span.
