Reading the passage

The scientists watch what happens in modern dunes, then use that relationship to reconstruct ancient conditions. Today, clay builds up only when vegetation stabilizes a dune. If the ancient deaths involved that clay-assisted process, the ancient dunes must have been stable and vegetated too.

What we’re looking for

Our analogy should use observations of a present-day process to help explain how something happened in the past. It isn't enough for an answer to mention an ancient object or use observations in some other way.

Working the answers

  • A
    Correct

    The historian watches modern craftspeople make pottery similar to the ancient pottery. Seeing how the process works now helps the historian theorize about how it worked then. That matches using modern dunes to reconstruct the conditions behind an ancient geological event.

  • B

    Surveying people about their current employment gives evidence about current unemployment. There is no move from a present-day process to an explanation of the past.

  • C

    These manuscripts are evidence from the ancient period itself. The historian uses them to infer their authors' views, rather than watching a comparable modern process to reconstruct an ancient one.

  • D

    This runs in the other direction: past market behavior is used to predict the future. Our scientists use present observations to understand the past.

  • E

    Ancient objects provide evidence of what an ancient civilization valued. Like C, this uses surviving evidence from the period; it doesn't use a modern counterpart to explain an ancient process.
