Passage Summary: You can track where an old object has been by looking at the specific types of plant pollen stuck to it.

Conclusion: Analyzing pollen on the surface of an ancient relic is a reliable way to determine where it has traveled.

Reasoning: Relics can be linked to specific geographic areas by identifying pollen from plants that are unique to those areas.

Analysis: To weaken this argument, we need to find a reason why the presence of pollen on a relic doesn't necessarily prove the relic was actually in that location. Perhaps pollen can be carried long distances by wind or water, or maybe it can be transferred from one object to another much later in time. Look for an answer that introduces 'contamination' or 'alternative transport' as a possibility, which would make the pollen a very unreliable GPS for ancient history.
