Stimulus Summary

Lamps were present throughout the entire Upper Paleolithic period, but there are a lot more known lamps from the late period. This is when the Magdalenian culture was dominant.

Answer Anticipation

Let’s start as we always do - clearly defining the paradox. Here, the stem tells us what we’re trying to explain - the distribution of lamps that skews toward the late Upper Paleolithic.

Answer choices

  1. A
    Artifacts from early in Remaining source text redacted.
    Why choice A is not credited
    If the artifacts from the earlier period are harder to identify, then they may exist and just be harder for archaeologists to find. This answer resolves the paradox and plays off of the stimulus discussing “known” lamps.
  2. B
    More archaeological sites have Remaining source text redacted.
    Why choice B is not credited
    If there have been more Magdalenian sites found, and they were dominant in the late period, then that explains why more lamps were found from that period. There could very well have been just as many lamps earlier, but we haven’t discovered those sites yet.
  3. C
    More efficient lamp–making techniques Remaining source text redacted.
    Why choice C is not credited
    If the Magdalenians were more efficient at making lamps, then there were likely more lamps when they were dominant, and so the distribution is explained - there were more lamps in the later Upper Paleolithic.
  4. D
    Fire pits were much Remaining source text redacted.
    Why choice D is not credited
    If fire pits were more common in the early Upper Paleolithic, then there would be less of a need for lamps, and thus fewer would be made. The distribution of more lamps from the later period can thus be explained.
  5. E
    More kinds of lamps Remaining source text redacted.
    Why choice E matches the stem
    The kinds of lamps doesn’t determine or explain the total number of lamps made. There could be a single kind of lamp that is mass produced to a very high level; and there could be many lamps, each of which was made by hand by an artisan and thus very few were made.
