   Passage: Extracting ancient DNA from fossilized bones allows scientists to sequence ancestral genomes. Genetic tracking maps historical human migration routes, disease origins, and evolutionary relationships across millennia. What is the central idea?

9. MultiChoice

   Passage: Experimental archaeologists build replica ancient tools and structures using historical methods. Recreating and testing these ancient technologies reveals the exact skill, effort, and practical techniques original builders used. What is the central idea?

10. MultiChoice

    Passage: Ancient monuments face risks from severe weather, erosion, tourist wear, and armed conflict. International conservation coalitions work to stabilize vulnerable stone structures and digitally archive ancient heritage before it vanishes. What is the central idea?
