Question

which question is addressed in the eighth paragraph? a what did the researchers do and find? b why are researchers studying trachoma? c what factors contribute to recurrent trichiasis? d how can blindness from trichiasis be prevented?

Explanation:

To solve this, we analyze each option:

• Option A asks about researchers’ actions and findings. Paragraphs (like the eighth) often detail research methods and results.
• Option B is about the reason for studying trachoma (focus on “why study”), less likely in a paragraph about research details.
• Option C is about factors of recurrent trichiasis (causes), not typical of a research - action - and - finding - focused paragraph.
• Option D is about preventing blindness from trichiasis (solutions), not the main focus of a paragraph on research conduct.

Answer:

A. What did the researchers do and find?
