Digital SAT Reading and Writing Practice Question #603

Text 1 Advocates for the 'Clovis First' model of the Americas' settlement point to the sheer abundance of fluted projectile points scattered across North America, which definitively date to approximately 13,000 years ago. These advocates argue that this widespread archaeological signature represents the initial wave of human migration into the continent. While purportedly older pre-Clovis sites exist, Clovis First defenders contend that these older sites universally lack undisturbed stratigraphy; they argue that artifacts found in these older layers are the result of post-depositional mixing, where newer human artifacts shift downward into older geological sediment. Text 2 The recent discovery of fossilized human footprints in White Sands, New Mexico, has instituted a massive paradigm shift in American archaeology. Using highly precise radiocarbon dating of ditchgrass seeds embedded in the tracks, researchers conclusively dated the footprints to between 21,000 and 23,000 years ago. Crucially, the footprints are visibly impressed into distinct, unbroken geological layers of ancient lakebed, utterly ruling out the possibility that the human evidence could have migrated from a higher, younger stratum. Based on the texts, how would the author of Text 2 most likely respond to the specific contention made by the advocates in Text 1 regarding 'older sites'?
